How do rivers form? (surface and groundwater flow)
Вставка
- Опубліковано 31 січ 2021
- In this video, we will look into why water flows in rivers long after the rain has stopped. Where does the water come from? We will learn that rivers are fed from surface runoff, as water flows over the surface during, or shortly after it rains, but also through their beds, by groundwater which infiltrates through the soil and is stored in the pores of rocks in large underground reservoirs called aquifers. Finally, we will see that some water also comes from the melting of snow and ice high up in the mountains.

good presentation, I honesty was bored and was thinking "How do Rivers start?" and found you!.
same i got no business in knowing this but glad i did!
Same
Same here 😅
@@TheJuize85 next I was looking up sewers ahahah
Same
This is the 4th video called "How the rivers form/are formed" and it's the FIRST that actually explained how the rivers are formed and not the parts of a river like meanders.
Kudos to you to actually describe the topic! You earned the subscription.
Do you know if there any rivers that are fed by the ocean?
I'm surprised that you didn't mention *springs*. They play a very important part in how rivers form - in fact, the "source" of many rivers is a spring (or sometimes a number of springs).
So smiple and easy ! Wow
Any DMs here making a campaign map? Lol
I'm a player actually and was thinking about if I ever become a DM I want to be geographically realistic lol
Such a great and understandable presentation ! Well done
Thank you.
God bless John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
i was doing bad in exams for geo but with this channel i did good :) ! thank you so much!Good presentation
I am happy to hear we were able to help. Good luck for the rest of your exams!
Thank U madam , now I find the actual source of rivers .❤❤
Your voice is very, very relaxing. Keep up the good work!
Learned alot. God bless
Thanks akkaa Saved My LIFE!!!
Great video, thank you so much
So clearly explained! Wonderful. Thanks. I learnt a lot.
Wonderful, i like this, thanks for beautiful explanation. ❤

love it,i looking forward to see more videos from uou guys!
Thank you. I am working on it!
Very good video, thank you.
Thank you
Appreciable content ❤️
This was a great video! I typed in "why do rivers exist" and found this! Subscribed.
Thanku a lot a lot. I have my test tomorrow and was not able to understand this concept. I watched many many videos but your video is the best. 😊👍⭐
i am currently making a computer game and this is great to know for the part im at now, which is creating the landscapes. Merci!
Superbly explained thank you.
Thank you
I love it
Good presentation. I had so many questions about rivers and this vid awnsered them all. You have a very relaxing and calming voice, i could listen to you talk about how grass grows and i would still be interested😂😊
Some of rivers start from lakes for example : Indus river ( starts from maansarovar lake) , Brahmaputra ( starts from maansarovar lake)
Thank you so informative 🥰
Thank you

I live in mountains, there's big waterfalls from the mountains peak, where is the water come from? And this mountains have no glacier, i live in tropical country
Becouse of the pressure
Rain falling on the mountain
I believe that it comes from deep in the earth. But can't find evidence to prove that!
aliens
Ground water my friend
Ma'am this explanation was very detailed and well presented.
How wonderfully you explained it🙂👍
so easy to understand more videos plsssssssssssssssss !
This channel needs more subscribers. Such a good presentations
Thank you. You are very kind.
Yes I like it
i got my answer of my curisioty thank you
Imagine mankind having the ability to just observe these things. No classroom, no teacher, no grading and memorization system that keeps the student anxious instead of enjoying the process of learning.
Can u tell importance of fast flowing rivers. Please
Interesting
I often wonder if one could make a river in places where water teends to go.. first by creating a pond.. then the water table will refill, do that for a couple years.. then extend the pond like a river and just keep doing that for decades... is it possible?
You can divert the path of an existing river but you cannot really create a brand new river just by digging somewhere beacause as soon as the river is bed is higher than the water table it will loose the water. To prevet that from happening you would have to make the river bed impermeable.
Thanks i was just curious had to find out
Thank you for the nice comment
Ooohh ok, i was thinking where does a waterfall starts, so ok it starts here after millions of years where the rock cannot hold the water and some underground rocks eroded, then it will become a waterfall.. Now I get to understand it more :)
So basically, it starts of as a spring then after several miilions/billions of years it will form a waterfall then be a river? Or spring>river>waterfall?
Very informative maa'm. And sweet accent too!
Thank you!
U r voice is so beautiful 😍
When you maintain a curiosity, you will never be bored
🙏
Exactly what I was looking for. 👍 Thank You
You are welcome
Now I can sleep again. Thank you.
Super extra terms . I almost went napping by the bring as voice
Thank you..i get a fact..
Okay so this explains only why rivers stay with water in them and where it comes from but, it doesn't tell you how rivers are FORMED like the title suggests.
How is a river formed? like how does the land separate originally in order for water to even pass through in the first place? Are they natural? are they Man-made?
Is it simply gravity and wherever happens to be the lowest part of land it can reach is where the river basin forms and thus grows into a river creating a bed for itself as it corrodes through the landscape?
"And it is He who has released the two seas,one fresh and sweet and one salty and bitter,and He placed, between them a barrier and prohibiting partition.
Surah Al Furqan,
I learned this before, it starts from a spring water and then it become deeper and lomger
Not always
Great video, lot better explanation than my girlfriend
It can make people Smart
Does the water in the rocks also freeze during winter?
yes! and because when the water freezes it expands it may even break the rocks apart!
Surah Al-Baqara, Verse 74:
ثُمَّ قَسَتْ قُلُوبُكُم مِّن بَعْدِ ذَٰلِكَ فَهِيَ كَالْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةً وَإِنَّ مِنَ الْحِجَارَةِ لَمَا يَتَفَجَّرُ مِنْهُ الْأَنْهَارُ وَإِنَّ مِنْهَا لَمَا يَشَّقَّقُ فَيَخْرُجُ مِنْهُ الْمَاءُ وَإِنَّ مِنْهَا لَمَا يَهْبِطُ مِنْ خَشْيَةِ اللَّهِ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ
Then your hearts hardened after that, so that they were like rocks, rather worse in hardness; and surely there are some rocks from which streams burst forth, and surely there are some of them which split asunder so water issues out of them, and surely there are some of them which fall down for fear of Allah, and Allah is not at all heedless of what you do.
(English - Shakir)
via al Quran
Our al quran book really amazing, it tells you before science do study ❤
I think i'm not the only one who's enjoyed her accent in here ❤🗿💀
nice
Thanks
So it’s possible to make a man made river all you need is the rocks and water

This was mentioned in the Quran 1444 years ago, before all the scientific advancements.
"Even then your hearts became hardened like a rock or even harder, for some rocks gush rivers; others split, spilling water; while others are humbled in awe of Allah. And Allah is never unaware of what you do." Quran 2:74
Wow, what a good presentation, I needed this
Thank you for the nice comment

I thought the Trees is responsible for creating water for rivers!!! Haha
river paths are naturally made when the earth was hot and soft and molten
That is incorrect. The surface of the Earth is continually being reshaped and remodelled and rivers play a big part in it. The paths or rivers change constantly, sometimes very gradually, sometimes dramatically. It is for example not uncommon for a river to alter its path following a big storm. Besides, when the Earth was hot and soft and molten (as you say) there was no liquid water on the Earth's surface. It takes at least several hundred degrees for the rocks to be molten, and all the water would be transformed to vapor.
Bro I though shawty was taking a piss in the beginning
Good video but didn't quite got my answer
River forms due to headword erosion !
Geomorphically speaking it starts from the Ocean it joins !
Thank you for the beautiful presentation and facts in this video and channel. 🌹
I would kindly like to add that this wonderful on-rush of water was surprisingly highlighted by God AlMighty;
"For indeed there are rocks from out which rivers gush, and indeed there are rocks which split asunder so that water floweth from them." (2:74) Al-Baqarah.
How Great is God ?
Thank you for the nice comment.
This is one of the examples which made me choose Science
And now …..☠️
You answered how rivers are replenished and maintained with water but not how rivers are formed.
Hello and thank you for your interesting comment that allows me to explain better. We may think that rivers are static features or networks of carved out channels that are then filled with water (if I understand your comment right this is what you imply), but that is not really what happens. In fact rivers are highly dynamic systems, their paths is determined by topography (i.e. the shape of the land over which the water flows ), the type of rocks that make up the land, but also by how much water there is and how fast it flows. Moreover, rivers themselves can change the landscape, through erosion. When water flows it will carve its own path over time. These paths, are not fixed : it is not uncommon for a river, or a portion of a river, to change path, sometimes gradually, often suddenly. So for many practical purposes, the water is the river. In this sense I think that if you can explain how water gets to the river, you can explain how the rivers are formed.
How does underground water rise up in the mountain?
The water does not climb up the mountain. It falls from the sky and starts movinf downwards towards the sea. Some of this journey happens at the surface, some undergroud. If the level of the water underground rises above the level of the surface, the water comes out (that is how a spring forms).
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the Anointed is Lord! Repent and be baptized and believe the Evangelism.
Ok
The most interesting think about rivers is the fact, that they are formed like Lichtenberg-Figures, like electromagnetic discharges. Nobody seem to care or explain why though.
The quraan 1400 years ago states that some rocks form rivers. SubhanAllah .
made it too compilcated to understand untill 04:20 🤭
Okay show me an real example where the river STARTS
Hi @clipper4me, here is an image o fa spring (the place where the water comes out of the ground) en.wikipedia.org/wiki/Mur_%28river%29#/media/File:Murursprung01.JPG
Ay ngeke vumani ukuth anazi ayikho lento echazwa la
❤️👏
This exact scientific phenomenon has been mentioned in the Quran 1400+ years ago
Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allah. And Allah is not unaware of what you do.
Quran 2:74
Surah Al-Baqarah Ayat 74
Why then do you not believe?
For indeed, it is not eyes that are blinded, but blinded are the hearts which are within the breasts.

Comes from under ground
why french
and people say there is no God. thats laughable
Slightly mystified that God sends you to our youtube channel, but then again who am I to question God's judgement? :-J
We base our perceptions of reality based on subconscious calculating, beliefs, preferences-- much more than we realize. I agree it's a spiritual crime to just tell people what is important or not... To each their own, living for the tangible but be cursed to see it all decline, or to live in fear or perhaps pseudo hope/ or grandeurs if there are redemptions after death...
Just would be nice either way- if the human race could be decent and get along for once... Even within the same company/ agency... Is that really too much to ask for??...

rivers receive VERY LITTLE water from the "water table" 99% of the water comes from the snow peaks and ground runoff, the fact this video spent so much time talking about the water table is why people are so stupid.
Dear Philipp, it really depends... some rivers are indeed in large part fed by glaciers and runoff, but there are many others that are not... First of all, many rivers do not originate directly from glaciers but from springs (a spring is where the water table reaches the surface), secondly the entire premise of the video is to discuss why is there water in the river even when there is no surface runoff.... Finally, I am not sure what river you are referring to as fed 99% by snow and surface runnoff, but as far as I know, they are not very common : even in the Himalayas glaciers provide, at peak season, only a maximum of 80% of the water in the river (see Rowan, A. V. et al., Geological society spec. pub. , 2014) and, as another example, the Upper Colorado River (which receives plenty of snowmelt and runoff), has been found to have roughly 50% contribution from baseflow (see Rumsey et al, Journal of Hydrology, 2015) . IN ANY CASE, lowering of the water table has major consequences to the amount of freshwater available in rivers and understanding the relationship between ground and surface water is ESSENTIAL to properly manage our water resources and more generally to understand the water cycle . Failing to do so would be , maybe not quite stupid (I actually do not believe people are generally stupid), but let's say ignorant ?
such theories can not justify how such river Nile and all other rivers on our earth was there since thousands of years. how much water needed to be enough for these rivers???? Nop. there is something wrong or hidden we don't know.
This is meant to be a short summary of how most rivers get their water. If you have a specific question on how water reaches the nile you can look that up. Saying there's something we don't know just because it wasn't mentioned in this specific video is pretty stupid.
@@Sucharush31 i believe the stupid is the one who takes the changeable data as the constant fact.
@@mohamedaldawy5840 no it's definitely you who says "your wrong, it must be something else" and puts in literally 0 effort to research or backup any of your claims, much less put in the effort to make a reasonable counterargument as to how it actually works.
@@Sucharush31 i have logic. This is simply my reply. I’m not blinded mind. Blind faith in scientists is the real stupid.
