Scrat: *_NO, I JUST WANTED TO EAT THIS SEED INSIDE THIS ACORN! PLEASE STOP SENDING ASSASSINS TO KILL ME!_* Me: Deal with it scrat, we have other food items to eat besides acorns.
I love the details with the muskrat family. The two adults have a child, the child grows up and graduates (the mum either died or left), and the child moves out (the father died I think), and when the muskrat is looking at the billabong it thought that a family of other muskrats had died. Amazing attention to detail.
1:18 Notice that the family picture has been torn removing one of the parent muskrat, probably the father. Their relationship must've become rocky when their child moved out of the house until they finally divorced. Mother muskrat was left to die alone, explaining the lonely set of skeleton where she once stood.
+Gabriel Hortaleza It's not really a sad story; they make a home, grow old, and eventually die after their young have moved on. It's the story of all life in a time lapse.
The dad definitely wasn't being swept away. The muskrats need to swim out of their den every time they forage for food. The skull with the picture still hanging on the wall was sad though.
The northern pole is made of 50% frozen water and 50% frozen CO2. The southern pole has some specks of water. So there definitely is and has been water on Mars. The question is how much. We don't know if those rivers have been formed by water. Maybe it was methane or liquid CO2 from all we know.
Mars possibly had flowing lakes, oceans, rivers, lakes, etc at one point, lots of former lake beds and shapes that are created by rivers/ oceans/ lakes/ etc are there: such as certain canyons on mars.
I had garden soil dumped on my driveway and I had transferred most of it, however it rained, and when I went back to look, it had these perfect wavy ‘rivers’ where rain water had passed through the left over soil. It looked really impressive
Your statement proves this video's explanation lacking. Viktor Schauberger offered a far better explanation to why rivers / streams curve. He was brilliant.
You studied geography so that you'd know the name of the countries outside your border or have the knowledge in how to find the said country on the map. And the name of your states/provinces/region. Stuff like that. Hey, at least when some head of government say lets go to war with country A, you'd know where that country is and its geopolitical relation with its surrounding countries and its problem with your country.
The mars thing was a bit of a curve ball. I knew about mars having liquid water, but seeing the river formation was a real eye opener. Its something familiar on an alien world, which is really neat!
@@yousefabdelgaber7498 I think your confusing that with Saturn's moon Titan, mars did have water at some point leaving these river marks but no methane rivers there,
I like the nice touch of having the rover speaking in binary while posing the question of what Martians call their oxbows. Because Mars is populated exclusively with robots.
That was extremely educational, and reflects some of the decisions that are being made in the Netherlands about taking away retaining walls and restoring natural river routs to combat frequent flooding
Check out the border between US states Arkansas, Louisiana, and Mississippi. It's interesting to see the borders were drawn a while ago when the Mississippi river used to curve certain ways. Now the river is different but the borders remained the same.
I shared this video with my 8th grade earth science teacher and she absolutely loved it. This video taught the mechanics of rivers better than any single diagram alone and it’s helped so many students

1:28 It's called a thallwag. The strongest thallwag is the one that is not in contact with the river banks. This chapter is honestly the easiest chapter of Physical Geography. I used to be able to explain rivers, meanders, waterfall, gorges, deltas, braided rivers, etc in one go. I wish I could still do that. I felt so smart back then.
*wrong* The word is thalweg and it is the line that joins the lowest points of the river bed's cross section (or on land of a valley). It derives from the German geological term Talweg, literally meaning 'valley way'. It is never where the strongest current is, as that is slowed down towards the margins of the bed due to friction. The lineof the strongest current is called the current thread.
A question I've never asked myself but one i wanted an answer to the exact moment i saw this thumbnail on youtube. And the icing on the cake, straight to the point! You don't know how good that is. I usually jump a couple of minutes because is so much filler in the beginning. 11 out of 10!
That was brilliant! Great video, explanation, pace even was awesome. you took something honestly that was so so interesting and explained so thoroughly yet quick and dummied it down to the perfect level. Bravo
This is my favourite minute earth video! That aha moment that made me understand why rivers meander was just amazing. I hope my content can have the same explanatory power as yours does one day.
Interesting, informative, right to the point, easy to understand, and tought me about a natural lake that i didn't even know existed, and now know how its formed. What an excellent video! Thanks guys!
Chapters: 1: How it forms? 2: How it's curved 3: lengths of a meandering curve's differences in size 4: how the river's meandering looks like if nothing is ever in it's way
EB Productions Try converting what Curiosity says, 0011111100100001, to text somewhere like here. www.roubaixinteractive.com/PlayGround/Binary_Conversion/Binary_To_Text.asp
I've never heard of a "hoefijzermeer" before, even though I am Dutch. However, I **have** heard od an "oxbow lake". Strange things, languages; I know words in English that I don't know in Dutch and vice versa...
This video is entirely wrong. Curves are caused by the moon and its gravitational pull. As it orbits one way, it pulls the stream to it. Then when the moon passes from the opposite horizon, it then pulls it back the other way. Perhaps if the author of this video had of visited /r/science on reddit, they would have known this.
I read something like this on lies my History Teacher told me. Another lie was that the Athenians made the first written language, NOPE, it was Africa Visit us at /r/blackhistory on reddit to learn more.
But, and correct me if I'm wrong, aren't there studies that liquid water tends to meander even on really uniform, level, hydrofobic surfaces? Why is that? I mean, there can be no soil and very little irregularities to start the meandering. Is it just that even a small difference is enough to kick this process into progress? (Will try to find a source, and come back to edit it in later. Possibly an answer even, if I can find one.) EDIT: Okay, here's one source article from 1984 Cambridge: journals.cambridge.org/download.php?file=%2FFLM%2FFLM149%2FS002211208400255Xa.pdf&code=1eeff1156ef7a855ec9cdaa4de02bcf5 Will keep on looking for an answer. Based on the synopsis, that paper might even have some answers, but don't have time to go through it right now... :/
So I read that, and did some Googling because lolwut hysteresis. So the paper suggests that it's caused by surface tension. Basically, the water hitting the surface of the plexiglass comes in contact with the irregular (on a microscopic scale) structure of the polymer. This causes the water to have irregular surface tension, which "pulls" the water towards the thinner side (higher surface area/volume ratio). Then as the water starts swinging in that direction, which part of the stream is thinner changes, pulling it back in the other direction. This forms the meandering path a river usually takes. All of which does NOT suggest this effect manifests on the scale of entire rivers, and the explanation presented in this video is agreed upon by every credible source I can find.
seigeengine Ah, thank you very much :) That sounds like a very reasonable explanation. I wasn't suggesting that the explanation on the scale of rivers presented here is wrong, I had heard this elsewhere before in some form as well :) I was just interested to know, what the explanation is on the small scale "smooth" surfaces
EdwardBerner I just didn't want anyone going around telling people rivers meander because of surface tension. :P This is a really interesting topic for me (particularly the patterns) because I have a minor interest in terrain generation. I remember a few years ago I coded up a map generator that used multiple layers of perlin noise representing different factors (temp, humidity, and elevation if I recall), and then based on that coloured in the regions differently based on a set of biomes. Now, it didn't very well represent realistic terrain, but it was appealing, and it would certainly suffice for fantastical settings. Being able to add realistic details, like weather factors, rivers, etc. would be great. Especially because with rivers I could likely implement some kind of populator that would place cities around the map too.
I had known about the slingshot effect from before, but always kinda wondered if the bends would become so big that they meet again. now i know they can! thanks for explain it as well as showing great examples to understand and visualize.
I learn lots of useless information at school, but never ever they told me this. I had to memorize the capital of every country in the world, but I didn't had to explain some elementary things like this.
I remember this being taught by our geography teacher in 9th grade but i never understood it properly, i think its cuz i was too little to understand it then, it should be taught in 11th or 12th. Btw, thnq for explaining it🙏🏻
The river Meander, from which the verb meander originates, is in western Türkiye. It is called "Menderes Nehri" nowadays. It meanders gracefully through several plains and flows into the Aegean, near where I live.

It derives from the German geological term Talweg, literally meaning 'valley way'. It is never where the strongest current is, as that is slowed down towards the margins of the bed due to friction. The lineof the strongest current is called the current thread.
Neat and quick explanation for something that I didn't know I cared about, this channel is great.

My question: did the rivers on Mars, since they're subjected to different gravity, have a different ratio of periodicity of their curviness to width?
Your the only one who actually helped me understand undercutting thanks
My exam is tomorrow, and watching this video craps up the materials required. Thanks a lot. Liked

I prefer "craps".
A question I've never asked myself but one i wanted an answer to the exact moment i saw this thumbnail on youtube. And the icing on the cake, straight to the point! You don't know how good that is. I usually jump a couple of minutes because is so much filler in the beginning. 11 out of 10!
"It's curves will become curvier and curvier, until it loops around and bumps into themselves."

That picture of a dried river on Mars... woah.
That was brilliant! Great video, explanation, pace even was awesome. you took something honestly that was so so interesting and explained so thoroughly yet quick and dummied it down to the perfect level. Bravo
Wonderful explanation. Also I like the new voice. Great addition to an awesome channel.
Hahah, I finally know what a billabong is.
Once a jolly swagman camped by a billabong
I know right!!! I just knew it was a small lake near a river. But not the details...
***** You know that a Billy is actually a Camping Kettle right,
Did the dingo eat the baby in the billabong?
did i just fall in love with geography ?
The got attached to the rats and got happy when the child went off to college and got sad when one died :(
This is my favourite minute earth video! That aha moment that made me understand why rivers meander was just amazing. I hope my content can have the same explanatory power as yours does one day.
Damm the rat must have been a motivation speeker. He proved that all it takes to bring a big change is just confidence and small step...
bruhh bro
First video... This was a brief but more inciteful than most longer videos. I am subscribing
its MUCH better now i turned it into a rap on my channel!
Really excellent video, thank you.
Interesting, informative, right to the point, easy to understand, and tought me about a natural lake that i didn't even know existed, and now know how its formed. What an excellent video! Thanks guys!
Oxbow lakes are formed when a river's meander is too wibbly wibbly wobbly to maintain the course it's on.
just like humans it takes grate effort to follow a straight path.
The main flow of the stream diverts itself accordingly, leaving the oxbow lake behind; but here's my question son.
What the hell's an oxbow, are our bovine friends fashioning weaponry ? someone should tell me , do i need to buy a shield ?
Chapters:
1: How it forms?
2: How it's curved
3: lengths of a meandering curve's differences in size
4: how the river's meandering looks like if nothing is ever in it's way
that last question hit me hard!
Same here :D

A rare case of aha moment struck me watching this video. Subbing
I was so sad when i saw the skeleton in the cave at 1:13 :(

I'm quite certain they died from old age (their child seems to be growing up in some previous frames)
Short and straight to the point. If only TV ads were all like this.
I've never heard of a "hoefijzermeer" before, even though I am Dutch. However, I **have** heard od an "oxbow lake". Strange things, languages; I know words in English that I don't know in Dutch and vice versa...
so what you are telling me is that a river + darth vader + hour glass = song wiggle wiggle wiggle 0:33
This video is entirely wrong. Curves are caused by the moon and its gravitational pull. As it orbits one way, it pulls the stream to it. Then when the moon passes from the opposite horizon, it then pulls it back the other way.
Perhaps if the author of this video had of visited /r/science on reddit, they would have known this.

Christian Tipling How is that relevant to what i said?
I love how during the explanation with the muskrat disturbance that if you watch closely you can see the muskrat family slowly grow up
But, and correct me if I'm wrong, aren't there studies that liquid water tends to meander even on really uniform, level, hydrofobic surfaces? Why is that?
I mean, there can be no soil and very little irregularities to start the meandering. Is it just that even a small difference is enough to kick this process into progress?
(Will try to find a source, and come back to edit it in later. Possibly an answer even, if I can find one.)
EDIT: Okay, here's one source article from 1984 Cambridge: journals.cambridge.org/download.php?file=%2FFLM%2FFLM149%2FS002211208400255Xa.pdf&code=1eeff1156ef7a855ec9cdaa4de02bcf5 Will keep on looking for an answer. Based on the synopsis, that paper might even have some answers, but don't have time to go through it right now... :/
So I read that, and did some Googling because lolwut hysteresis.
So the paper suggests that it's caused by surface tension. Basically, the water hitting the surface of the plexiglass comes in contact with the irregular (on a microscopic scale) structure of the polymer. This causes the water to have irregular surface tension, which "pulls" the water towards the thinner side (higher surface area/volume ratio). Then as the water starts swinging in that direction, which part of the stream is thinner changes, pulling it back in the other direction.
This forms the meandering path a river usually takes.
All of which does NOT suggest this effect manifests on the scale of entire rivers, and the explanation presented in this video is agreed upon by every credible source I can find.
seigeengine Ah, thank you very much :) That sounds like a very reasonable explanation.
I wasn't suggesting that the explanation on the scale of rivers presented here is wrong, I had heard this elsewhere before in some form as well :) I was just interested to know, what the explanation is on the small scale "smooth" surfaces
EdwardBerner I just didn't want anyone going around telling people rivers meander because of surface tension. :P
This is a really interesting topic for me (particularly the patterns) because I have a minor interest in terrain generation. I remember a few years ago I coded up a map generator that used multiple layers of perlin noise representing different factors (temp, humidity, and elevation if I recall), and then based on that coloured in the regions differently based on a set of biomes. Now, it didn't very well represent realistic terrain, but it was appealing, and it would certainly suffice for fantastical settings. Being able to add realistic details, like weather factors, rivers, etc. would be great. Especially because with rivers I could likely implement some kind of populator that would place cities around the map too.
seigeengine Basically the same as how people think the Coriolis effects drains and the way water flows... wrong scale : P
azmanabdula Mhm, but it is interesting how water has the same behaviour on two scales for two entirely different reasons.
Didnt realise I needed to know this. Thank you!
I had known about the slingshot effect from before, but always kinda wondered if the bends would become so big that they meet again. now i know they can! thanks for explain it as well as showing great examples to understand and visualize.

In other words:
OXBOW LAKES ARE FORMED WHEN A RIVER'S MEANDER GETS TO WIBBLY, WIBBLY, WOBBLY TO MAINTAIN THE COURSE IT'S ON.

I learn lots of useless information at school, but never ever they told me this. I had to memorize the capital of every country in the world, but I didn't had to explain some elementary things like this.

This cleared everything which didn't use to make sense a year back when I was in my geography classes... Thnx alot...
I remember this being taught by our geography teacher in 9th grade but i never understood it properly, i think its cuz i was too little to understand it then, it should be taught in 11th or 12th.
Btw, thnq for explaining it🙏🏻

The river Meander, from which the verb meander originates, is in western Türkiye. It is called "Menderes Nehri" nowadays. It meanders gracefully through several plains and flows into the Aegean, near where I live.
