When your teacher says "watch this video" and then walks out of the building saying "see you Friday"
I'm gonna name my dog Alfred after this straight baller of a scientist. Froze to death looking for the truth. That's how a great man dies.
hat's off
A.Wegener was wrong. There is NO continental drift. The Earth gradually expands in reality.
As A Geography Teacher Based In Kenya, This Is One Of The Best Break Down Of Continental Drift Theory.
The continental drift and plate tectonics hypotheses are wrong, because the Earth is gradually expanding. Mantle convection can not explain the drift of small and large pieces of the earth's crust. Just try to model all these processes!
I noticed this at age 6, over 60 years ago. Being so young, the only way I could put it was, "South America goes out where Africa goes in." lol When I earned about plate tectonics in the 1970s I was happy to see that my 6 year old eyes hadn't deceived me. Just subbed.
who are here for earth science on quarantine?
im here because our teacher's making us do an activity on it :P
@@hyper.official @MyArT Book I'm doing this 2 days before its due 😂
@@hyper.official do you go to school in England?
@@theo5860 Noo unforunately i study in the Philippines
@@hyper.official oh, i thought from the time zones and language it was English
I thought this video would be boring, but I was totally wrong.
This was an amazing and super interesting video.
Keep up the good work!
I agree,
The video is not boring, but it is totally wrong. The Earth is gradually expanding, and all thinking people should realize this phenomenon. Unfortunately it would take significant time to dewstroy all the erroneous constructions ("subduction", @convection"...) of the "plate tectonics theory" which was the biggest mistake in geosciences in 20th century...
This is very educational but this guy’s voice is so relaxing almost thought I was listening to an asmr
Same
Use headphones
ur voice is relaxing, why all science "teachers" have this relaxing voice
video on 1.5x speed is necessary tho, he speaks very slowly
You should make more video's, your way of teaching is so easy to understand, and it really helps!
A moment of silence for Wegener.
You did a terrific job with this video. I will be using it with my Earth Science students on Thursday!! Thank you for putting it together.
This was a great explanation. Indeed Alfred Wegener was a great man with a great mind. Thank you for explaining it so brilliantly!
Glad you enjoyed it
For all of us that went to school in the 1980's mentally I am waiting for the little beep of the flim strip to advance the frame. Good information to have repeated anyway.
Wow! You explained this theory perfectly! I have an exam in science in two days. This will be very helpful, thank you!
That's legit what I learned yesterday day on school
Fuck off you play fortnite
Why don't you just shut up and stop being toxic kid.

@george I agree
First of all. Why u ppl have to be so mean, and tnot to also be rude, but its “in school” not “on school”
Hey Mike, Can you please make a video on Folds and Faults ?
Its my request to you because I really like the way you explain all these things.
This is a very good video and I plan to share it with my students as a review of Wegener's evidence of Continental Drift. My only complaint is your use of the word, "Theory." Continental Drift, was an idea, a hypothesis. His idea of continental drift later led to the theory of plate tectonics. This distinction is important in science and the casual misuse of the word 'theory" causes confusion for the general public. Please consider revising that portion of the video in your future updates. Thank you for your work.
Yeah, theories are well-supported and explain many different phenomena (like plate tectonics explains basically everything about terrestrial geology) while continental drift is a hypothesis, an idea, a possible explanation for a certain thing.
Is it just me, or this this actually the only interesting video your science teacher makes you watch in online school??
Thanks you this was an assignment to watch and white notes on and you were very clear
Thanks for the video! It helped a lot
Thank you Mike,you are one of the best teachers ! This will help us,at school.
Thank you a lot!!!! That is absolutely great! Much better than my doctor ❤❤
Good video Mike, well done.
This video made me emotional, God bless Wegner's soul, I stan
Wegener was a cold hard man who never knew there were rocks on the bottom of the ocean.
I saw a TV show when i was a kid about this rabbit that actually sawed the state of Florida right off ! I wonder if this was how the continents separated.
I love your videos! Keep up the good work my man.
can you make a video on Plate Tectonics?
this helped so much
Great video and narrative. Hope to see more from you.
I've been thinking about this a bit and I want a pangea map with all ancient ruin locations pin pointed and see how close they are in proximity to each other . Would explain alot of rock being moved from far off locations .
Pangea existed 300 million years ago. Not even mammals existed back then let alone humans. The ruins are hundreds, thousands or at best some 10 thousand years old.
While cool prospect. Pangea existed millions of years before even the earliest signs of homanid shelters. In fact it seperated long before many popular dinosaurs even existed.

I am not a scientist in anyway. But since a young kid in elementary school seeing my first really realistic looking globe and having been told about Pangea. While looking at the globe the thought cane to me that maybe a giant ice comet or ice moon crashed into what’s now known as the Pacific Ocean causing the earth to break open from the impact causing three things to happen: 1. Pangea to fracture up into separate tectonic plates. 2. Enlarging the earth’s size by absorbing the extra material of the colliding object. 3. Maybe the reason the earth is 70% water.
The thing that gave me that thinking was Hawaii. Here was an the big island with smaller ones out in the middle of this giant Pacific Ocean. Like a giant pimple sticking out of the deep ocean. Which made me think of the images I had seen of a drop of milk hitting a cup of milk. It falls in then there’s a splash back, sending a drop up into the air. As this happens the milk creates a pimple like form from where the drop splashed back up out of. So maybe the impact of the larger object caused inner earth magma to splash up and creating the foundation for the Hawaiian islands.
Also maybe the moon is the drop that splashed back up and out. Creating the moon. I know this all sounds nuts, but as a kid I thought these things.
Still crosses my mind when I see satellite pics of earth. The Pacific Ocean just looks like it’s filling a giant area of the earth.
But I know today’s science can prove that all wrong. But I was a 10 yr old kid with an imagination
This version is a bit better than your 2012 video. I’m sorry I didn’t stumble upon this until 2019.
We are going to Greenland in 2021. I hope I don’t freeze to death. I thought his body was still undiscovered? Maybe it was just his journal that wasn’t found.
Thanks for information
Wow😮 this is awesome
The Best video on this topic thank you for the beautiful explanation
Great videos! Thank you so much for making and posting them all!!! Sorry to be greedy but the link for the worksheet gives an error message
Congratulations!
Wegner is a real genius ... Thank you Mr Wegner for your contributions
cough cough Wegener*
Wegener was wrong. There is no continental drift. A primitive hypothesis.
In fact, the continents are separated because the Earth is gradually expanding, and real scientists should think about the mechanisms of expansion.
@@Anatoly-Cherep so they were once together
@@T0mtoma Yes, the continents were together 150 mln years ago on a much smaller planet. But the continents have moved apart FOREVER, because the Earth is gragually growing. No future super-continent will be generated. That's the difference between falsy "plate tectonics theory" and true Earth expansion hypothesis! You will see in several years that the turth will become clear for the most of thinking people including "geoscientists" 😀
Wegner is an true scientist and an amazing man he spent his time to prove his theory and a true man will do anything to prove that they are correct. It is such a shame he was frozen to death I truly wish him a happy life in heaven
no mention of the iguanas or possums that are spread from Australia, PNGuinea, Mid Pacific Isles, and western americas. The Pacific split East Asia+Oceania and America apart just as the Atlantic split America and Europe+Africa apart. Such bio similarity is an inconvenience to standard plate tectonics, as it favours Growing Earth theory, so its ignored by mainstream geologists.
Growing earth is pretty obvious for 2 reasons, Nuclear fission in the core where the end products are less dense that the original material. The tons of meteorites which arrive every day.
Hey dude I just wanted to say you got some dope ass videos man
Hi Mike, Thank you very much for your very clearly explanation.
Beautiful job, Mike!
mike wazowski
Great video! Does Wegener have descendants that know of his accomplishments?
Great explanation
Glad it was helpful!
Who’s here for online skl work
This would help me a lot............
Very good video. Congratulations..!
Can I use some parts of your video in my video of urdu language please?
Hi Mike,
This is a great summary of Wegener's ideas, evidence and theory, with clear narration and graphics.....it's a favourite of mine to use with my Yr r class (Australia). May I have you permission to download this to our education video platform 'Clickview'? (we are not always able to access youtube from our classrooms.
A great summary of wrong ideas. Alas!
The Earth is surely expanding, and no chaotic continental drift ever happened in our planet. "Plate tectonics" is for kindergardens only.
Mike, I have a question. Mossasaurus is believed to have appeared in South America in the late cretaceous some 90 million years ago (e.g. Taniwhasaurus antarcticus specimen is dated circa 70 m.y.a.) in the shallow seas formed by the invasion of the new atlantic ocean into part of Patagonia. However, from the video I understood that Mossasaurus (freshwater, a different variation) is evidence of continents being joined initially, because this animal could not have survived crossing the Atlantic, and its fosils are found both in Argentina and in South Africa. Hence the ocean wasn't there at the time. What am I missing? Thanx.
I'm sure you've already figured it out but the animal he's referring to is "mesosaurus" not "mosasaurus" I made the same mistake and didn't realize I looked up the wrong animal haha.
Great video .......
Thanks!
got my homework done finally
i'm still doing it :(

Great thinking 😊
Plate tectonics. You were ahead of your time.
Plate tectonics is for the purpose of differentiating the iron that is trapped above the core, Earth is in the final phase of differentiation, that takes place ONLY in the goldilocks zone. As heavier material is sinking and lighter material is rising, this causes gravity and centripetal force to increase. The increase in gravity comes from the iron weighing more than the same volume of silicate. This means Earths core is getting denser at the expense of the mantle, allowing the mantle to become lighter with this exchange, leads to the increase in centripetal force. The increase in centripetal force is only acknowledged as increased surface speed, because the added centripetal force allows for Earths mantle to occupy a greater volume, therefore maintaining a 24 hour rotation. The greatest accomplishment was maintaining a 24 rotation during the crossing of the Goldilocks zone, this made life possible, without 24 rotation being fixed, we would not be here. The truth is, an increase in centripetal force always leads to an increase in circumference. Mars has a 24 hour rotation and its axis are tilted like Earth. Mars is half of Earths diameter, and its surface speed is half of Earths, this means if the same thing were to happen on Mars, where its heavier material sinks and the lighter material rises from the core, Mars too, will grow in radius and overtime will cross the Goldilocks zone just as we have. Earth is leaving the Goldilocks zone while Mars is entering. Earths dimise will be the lose of Moon due to increased centripetal forces and gravity pulling Earth closer to the sun, where the Moons density cannot go.

Whats updated from this video of Continental drift(2018) and the last one uploaded in 2013
So nice ❤️
Alfred Fegner, Alfred Vegner, yes pronunciation is amazing here
What did the people before the discovery of continental drift and tectonic plates believe made mountains, if not convergent plate boundaries?
Geologists thought that mountains were formed by the Earth's crust moving up & down, but not laterally.
@@GeoscienceImaging scientists have always thought that lateral subduction was happenning.. thats silly
Johnny L I don't know where you get that idea but it for sure isn't true. Wegener was the first to propose that continents move laterally, and most rejected the idea at first, and for the next 50 years.
Great
Yes Weser
Same
so the continent sat on the very edge of the tectonic plates just so could fit together and not talking about the continental shelves that surround each of the continents or allowing for any erosion over say 4.5 billion years or asteroids so this leads me to think this is a crock
The ocean floor is created in rifts and ridges. That is how the continents split in the first place. Then over time, more ocean floor was created between the continents.
The theory of evolution and the theory of continental drift are ver influential theories in human history.
The continental drift theory is the most interesting one to me.
P.S. today is the day Darwin submitted the ‘Origins’.
What was Pangea? Give me the time please where you said it
Worksheet links don't work... :+(
It has been noticed by some that if you place the continents on a smaller diameter earth then all the continents fit together, north, south, east and west. Even if you close the Pacific they fit together perfectly. The science community rejected the idea that continental drift was caused by an increase in diameter of the earth because no natural process could be found to account for it. So therefore this theory was replaced by the standard model with drifting plates, subduction zones and a constant diameter earth. There are two observations that seem to militate against this. One - how can plates be moved if the mantle circulations move around the earth, creating a push and a pull? Two - large islands are surrounded by midocean ridges suggesting oceanic crust under the continental crust stretching in all directions.
9:53 Seafloor Spreading is what comes to mind. Unfortunately Wegener failed to study this matter. After his death, scientists like Harry Hess proposed this Seafloor Spreading theory and it is mainly one of the strongest evidences you can find to back up Wegener's Continental Drift Theory...
Very smart
Good job wgener
scratch was my favorite character
alfred wegner was GOAT
So much have the continents moved in the last hundreds years?
Cool

I love the profile picture
The name of that force is Cosmic Power.
Wegener
I actually have a question I can't find the answer to.
How is Africa moving due to continental drift? Has parts of African moved up and down beneath the ocean?
I've heard theories of atlantas being in north west Africa. I'd like to see evidence for the "eye of Africa" being submerged underwater.
Thank you!
havent you heard of the afrikkan rift????
If you want to see , just go to Google Earth and wear it out.
See all thst you can never see from ground , you can see that the masses above the oceanic waters are the dead petrified body's of gigantic creatures and we live on top of them.
This of course is the reason for the flood., killing giants and gigantic creatures .
bright insight has a good video on this theory czcams.com/video/oDoM4BmoDQM/video.html
