I watched this like 5 times already. Watching this is a good preparation for a test.
yea
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!
This is one of the best educational videos I’ve seen on TH-cam!
Thank you! This helped me more than any class I took in environmental science or geology
Thanks for ALL your videos, Mike. I watch them often and they're very helpful and informative!
Totally appreciate your videos since 4 years
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 😆
This video helped me in how to explain it clearly for my science report. Thank you!
A GREAT overview of key concepts. This video made helped me understand. Thanks.
This helped me get a good grade on my test and highly recommended.
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.
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.
This is really what I was looking for. Thank You So Much.
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
Excellent explanation. Thankyou!🙏👍
Really enjoyed this. Love the presentation of this as a sequence of supporting the evidence. Thanks
Much appreciated!
Really helpful
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 🙏🏻😊💐💐💐💐💐
Shout out to Marie Tharp, an absolute legend. 💪
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 very much for this explanation, your presentation was very effective..
The older I get, the more spread out I am, too.
NICE EXPLANATION. THANKYOU VERY MUCH!
This was f amazing. Particularly the patterns of magnetism on the sea floor. Thanks
This was required for school please end my suffering.
Yoo samerzz help!!!!
Yo same

super interesting and helpful for my studies
Thank you, this helped a lot
very pleasing to the eyes! thank u so much, its very detailed and its easy to understand!!
this is so informative, really thankful!
Really fascinating.Grateful.
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!
Thanks so much, you helped me ace my test :D
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 awesome video and explanation. Thanks a ton !
Very Nicely Explained!👍🏻👌🏻
Such an amazing vedio with crisp explanation and animations.
thank you for your videos, I'm doing my best to learn
Awesome explanation !!!
Thanks, this is a wonderful teaching resource!
Glad it was helpful!
Thanks for the explanation 😊.
This is what I call Quality Content.
This is what I call torture
Earth is so cool
Very Good Explanation
woah. this was one of the most educational video that I've understood
Wow! Great explanation!❤️
Amazing!
Thank you so much
Thanks for the video sir!
this was amazingily well explained......
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?
Good Explanation given!
Wow, this helped me in my SCHOOL!
Wow this made me suffers in my SCHOOL!
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!
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
Thanks for explanation
Thank you!
Very good video
you are better than my science teacher.
Thanks a bunch!
Really helpful 🎉
So glad!
Yess.. you come back.. hi mike... could you make video about stratigraphy or igneous/ sediment structure..? Thanks
Go look at his rock cycle videos.
Great explanation 👍👍keep it up 😁😁
Nicely explained
Thank you very much.
Do you have an additional resource for this specific video (flow chart, notes sheet etc)? Great work and an awesome resource. Thank you.
just amazing! like it!
it was perfect, from the start to the end
Me: Curling my eyebrows cause I have a presentation for science
Mike: Lemme help you with that
Thank you prof
Now I understand, Thank you
Great job buddy..
Very informative
Thank you!!
bestvideo on this topic ,, animation is best
how do u explain thr western coast of North America and SouthAmerica also seem to fit together With Austra.
you taught me more in 13 min than he did in one hour class.
Thank you.
Amazing
that means that the atlantic is spreading while the pacific is subducting
No the pacific is not subduction. The Earth is simply getting bigger.
Excellent video! I literally learn more with you rather than with my professors, haha
Thanks
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
What does it mean by the rocks aligning to earths magnetism? Like how does that work
I Like your lesson so you going to be there to help me out with my class in geography lesson💖💖👨
Nice
how do you explain the pacific ocean age on your age map of the sea spreading
They can't with the current plate theory.....
i know and i love it and kinda mad cuz school teaches it as fact i never heard theory attached to plate techtonics or how rain clouds are not just formed from evaporation but also by the suns partical ionizing the atmosphere and getting worst as our magnetosphere weakens to. pisses me off i learn it through the climate change bull sniggels i could smell a mile away and not in a class room where we do go over these subject numerous times in k through12 not once did they say theory and they should have.

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 ?
Stretch marks - rapid, and factor in electromagmetic shots recorded in solidified rocks after stretching , noahs flood.
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.
Is it known how the lateral shifts (steps) formed. At visible at 5:38.
Looks like Earth is expanding
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? 😂
Awasome
Can't this evidence be interpreted as in favor of expanding Earth theory over orthodox plate tectonics though?
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.
