At 7:50 Sal says that from the underwater fault ridges there are alternatingly symmetrical aligned magnetic properties in hardened lava. This doesn't surprise me, BUT what does surprise me is that he says the flip-flopping of the magnetic poles is so abrupt. Seemly from north to south and then vice-versa. Wouldn't it take a gradual change over thousands of years to flip the magnetic poles of Earth?
Hi Sal. I was wondering how you were going to cover this topic. There is a video that uses a map from the National Geophysical Data Center that sows the Ages of the Ocean Floor. According to this video the earth is expanding, if you bury the more recent ocean floor under the older one... you get a very clear picture of how it expanded. You can check it out here: watch?v=PQSrsy9xg70 Would be great to hear your comments about it. Thanks!
Nealadams website shows this expando-planet theory in detail for not only our earth but other planets as well. Implication is an ever growing planet and Pangea by way of a much smaller earth.
Here's a crazy theory for you; what if Iceland was the cause of the plates moving? Like a shard of rock that happened to hit earth just the right way to stick in Like a dart and split the lithosphere. The cracks all radiate out from Iceland
Genesis 1:9-10 (ESV) 9 And God said, “Let the waters under the heavens be gathered together into one place, and let the dry land appear.” And it was so. 10 God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good.
Love your presentations. They're always clear and easy to follow.
Could you do a video on the Coriolis Effect. I am having trouble understanding it. Thanks in advance!!
It's been 7 years how are you?
its benn 11 years how r u?
Khan academy is amazing! I’m a supporter 👍🏽
Sal thanx alot, your videos have helped me understand science and other subjects much more easily :) thanx bro
@tttybhgf You are correct. Hope it doesn't confuse people too much.
Pls.. make a video on shadow zone
Thank you!
nimekueiewa khan upo vizuri
Fascinating
By the way, the point was to say "Nice to see some real science concerning plate tectonics on this site for a change"
Thanks very much for these videos. You are a fantabulous teacher!
lov da vido. I gathered big brain frm wach.
Sal is going to help me ACE (since I'm capable of passing) earth science this year!!
hii, hows life now?
Hi sa mga kaklase ko:))))

super.
I came here cause it is an assignment that i need to watch for Science
Me too XD!
Wait what is 5 evidence of plate movements? please tell me!!!
its the fossil evidenc:D
In the days of PELEG was the earth divided (archiPELEGo)
why did the poles switch from one place to the other instantly in opposite dirrections, wouldnt it be a gradual thing?
In the days of PELEG was the earth divided (archiPELEGo) pelagic IS THE EARTH GROWING LARGER.
It would seem that since lava has been and still is and will continue to pour out that there would be a gradual shift.
no sound
Wouldn’t they all move towards the equator?
Unless the earth is covered with alternating magnetic rings
wow how was that happen ning
thanx Khan.I'L surely ace the upcoming exam.Yep
who uses khan academy, when you go to school?

@lahoucine66 although new crust is being created are a spreading ridge, crust is being destroyed at convergent boundaries (subduction).

Mate you need a bigger curser
LMAO did anyone notice at 8:13 that he draws a down arrow instead of an upward-facing one?
what does he talk about?
this was not in the bible ಠ_ಠ

how does this video cause a religious debate?
bro 2011 is crazy tho the year i was born 💀
Since Google disabled the colors for like and dislike buttons, 3/282 people miss their intended button.
They did?
earth is growing, not moving around
@alkalait Hahahahaha, of course not! It was written by archaic, bronze aged men who knew absolutely nothing of modern science.
Good job ,,,'..😖😖dilke
Do I have to watch the whole thing💀🌚
Thank you!
