I watched this like 5 times already. Watching this is a good preparation for a test.
yea
But what causes the cycles of the earths double torus magnetosphere to increase causing magma to well up every 12,000 years for a 1,000 years?
Continental drift should be called continental rebound after Noah's tidal wave deluges hit up against Africa pushing the mid Atlantic ridge up and tearing the Pacific ring of fire apart.
The galactic Milankovitch cycles not you or co2 causes climate trends and this the millennium of climate change END TIMES.
Jesus God warned us.
I always look for your videos which are very helpful for my Earth Science class. Thank you Mr. Mike Sammartano
You make earth science interesting!
Thank you! This helped me more than any class I took in environmental science or geology
This is one of the best educational videos I’ve seen on UA-cam!
A really great video explaining seafloor spreading. I teach 6th-grade special ed, and this was so much easier for my students to understand then the textbook explanation. The narration is gentle and kind, as well. Thanks so much!
I feel embarrassed, we learnt this in year 7 and now in year 9 they are teaching it again! It's good to remember general knowledge though 😆
At the end of 13 minutes, I was thinking, is it over already? That was an awesome video. A little long to play in class, but still good, I can play parts of it. And no ads, even better.
Not sure how long your lessons are, but I reckon it's an ideal length to play in class.
This is really what I was looking for. Thank You So Much.
Totally appreciate your videos since 4 years
This helped me get a good grade on my test and highly recommended.
Earth is so cool
Thanks for ALL your videos, Mike. I watch them often and they're very helpful and informative!
Outstanding job Mike! Thanks muchly. I really hope you're getting funding to produce your videos.
Brilliant video.That explanation wAs the best I have ever seen.Clear and easy to understand.
super interesting and helpful for my studies
Thank you. 💐💐💐Wonderful explanation on “sea floor spreading”.
Absolutely amazing explanation ❤️❤️ . This video clarified concepts in great detail 🥰🥰 . Please make more geology/climatology/ oceanography etc. Videos 🙏🏻😊💐💐💐💐💐
Very nice video, many good pieces of information. However, I would argue that "supporting evidence #3" is better explained by proximity to continental masses than distance from ridges. The sediments come from erosion of areas above seawater. As you can see from the map shown, there is no consistent difference until very close to shore
Thank you so much, this video has been super helpful! It's much easier to understand especially with all the helpful images.
Glad it was helpful!
This video helped me in how to explain it clearly for my science report. Thank you!
Shout out to Marie Tharp, an absolute legend. 💪
I really like the way you explain, it's not fast or slow and I can understand it carefully really appreciate you videos. I hope you inspire a lot of teachers to copy the way you teach the calmness and gentle of your voice. love your videos

A GREAT overview of key concepts. This video made helped me understand. Thanks.
This was f amazing. Particularly the patterns of magnetism on the sea floor. Thanks
This is what I call Quality Content.
This is what I call torture
Thanks so much, you helped me ace my test :D
Thank you, this helped a lot
woah. this was one of the most educational video that I've understood
Very Good Explanation
Thank you very much for this explanation, your presentation was very effective..
very pleasing to the eyes! thank u so much, its very detailed and its easy to understand!!
Really enjoyed this. Love the presentation of this as a sequence of supporting the evidence. Thanks
Much appreciated!
Thanks for explanation
Very good video
Wow, this helped me in my SCHOOL!
Wow this made me suffers in my SCHOOL!
May you make video about histroy of plate tectonic as well... when the term of "plate" start used? Who use this term for the first time?
thank you for your videos, I'm doing my best to learn
Awesome explanation !!!
Very Nicely Explained!👍🏻👌🏻
Really fascinating.Grateful.
Tank you so much for the 3rd to help me out with my class in geography
My Favorite part of it pleases me know is that you are very intelligent
Ur videos help my son a lot keep up the good work
Thank you!
Such an amazing vedio with crisp explanation and animations.
this is so informative, really thankful!
bestvideo on this topic ,, animation is best
Important to note that Plate Tectonics is a "theory" and not fact. I think it's a greatly made video. Expansion Tectonics is gaining ground.
You're kidding right? I don't think you understand what a scientific theory is. Plate tectonics is definity fact.
@@guyskillen Do a simple search and you can see it's a theory. I'm not interested in argument about that. Just look into expansion tectonics and people like James Maxlow, Peter Woodhead, and Neal Adams. I hope it becomes an eye opener for you as it did for me. Good Luck!
@@keffenkanum yes it is the theory of plate tectonics. My point is you don't understand what a theory is in science.
It's very, very solidly established (no pun). And observable.
@@keffenkanum You and I both know it was not an eye opener for you. You are trolling.
Regarding Evidance #1: It would have been beneficial to show what "active faults" mean by layering a map of seismic activity (earthquakes) over the map of ocean ridges and seeing the correlation.
Otherwise, great video! I did not know about sedimentation thickness as evidance!
Excellent explanation. Thankyou!🙏👍
Really awesome video and explanation. Thanks a ton !
Yess.. you come back.. hi mike... could you make video about stratigraphy or igneous/ sediment structure..? Thanks
Go look at his rock cycle videos.
Thanks, this is a wonderful teaching resource!
Glad it was helpful!
Thank you very much.
Now I understand, Thank you
it was perfect, from the start to the end
Dam, thought I discovered a channel to subscribe to. But your topics are all over the place. And videos are few and far between.
Really helpful
Thanks a bunch!
you are better than my science teacher.
Thank you prof
NICE EXPLANATION. THANKYOU VERY MUCH!
how do u explain thr western coast of North America and SouthAmerica also seem to fit together With Austra.
Great job buddy..
this was amazingily well explained......
Thank you.
Thanks for the explanation 😊.
Good Explanation given!
Thanks for the video sir!
Really helpful 🎉
So glad!
Supporting Evidence # 1: The Seafloor has geology. 4:16
Supporting evidence # 2: Age of the Rocks 6:03
Supporting Evidence # 3: Thickness of the sediments on the ocean floor 7:37
Supporting Evidence #4: Patterns of seafloor magnetism 12:16
The video was great thank you. Although I would say, the seafloor spreading is well evidenced by the four major concepts you illustrated, and clearly movement of the landmasses is also evidenced in congruous fashion. However, plate tectonics is in no way evidenced or proven by seafloor spreading. Indeed, plate tectonics only comes into being when certain a priori assumptions about the Earth are invoked, thus requiring a new, unobvious and unevidenced theory to be "concocted", namely subduction. This then gives rise to plate tectonics. All of the information so well presented in your video, stands totally independent and without any need of plate tectonics, if one doesn't take for granted certain "obvious' and "unchallengeable", yet completely assumed beliefs.
Yes, the Earth is getting bigger. No doubt about it.
Stretch marks - rapid, and factor in electromagmetic shots recorded in solidified rocks after stretching , noahs flood.
Amazing!
Thank you so much
The magnetic bands all have the magnetic field in the same direction. We only have alternating patterns of strength and weakness in the same direction. Wouldn't electromagnetic standing waves produce the same artifacts? With the reversal theory, the magnetic poles have to reverse. Can anyone think how this is possible ?
Great explanation 👍👍keep it up 😁😁
you taught me more in 13 min than he did in one hour class.
Me: Curling my eyebrows cause I have a presentation for science
Mike: Lemme help you with that
Nicely explained
I Like your lesson so you going to be there to help me out with my class in geography lesson💖💖👨
OCEAN RESOURCES
Problems of developing ocean resources and ways to solve them
Progress in the field of science and technology has made it possible to significantly expand the scope and scale of using the resources and space of the World Ocean.
What does it mean by the rocks aligning to earths magnetism? Like how does that work
Thank you!!
Thanks
Very informative
A theory that explains the magnetic changes in the Earth's crust is the core remaining as it is, but the earth flipping according to the The Dzhanibekov Effect.
What? 😂
just amazing! like it!
Can't this evidence be interpreted as in favor of expanding Earth theory over orthodox plate tectonics though?
Amazing
A complete case that the sea floor is indeed spreading apart and that tectonics is indeed a real phenomenon. *sonar
Over time those poles will become haywire. *sonar

Wow! Great explanation!❤️
Is it known how the lateral shifts (steps) formed. At visible at 5:38.
is have a question. as new oceanic crusts are formed, is there a surplus of crustal materials on the Earth's surface?
I'm curious why you didn't talk about the west coast of North America and how that is all newer rock. I'm also wondering why there is no build up of sediment on the west coast if the continent is being pushed west by the seafloor spreading in the Atlantic. Shouldn't there be subduction on the west coat, which would leave sediment build up?
The Rockies were formed by the subduction you speak of. They are a young range, and still growing.
just watching this for school
Superb explanation
Excellent video! I literally learn more with you rather than with my professors, haha
Nice
Do you have an additional resource for this specific video (flow chart, notes sheet etc)? Great work and an awesome resource. Thank you.
