Plate Tectonics Basics

For an introductory college-level earth sciences class: a review of the basics of plate tectonics, including the three boundary types: convergent, divergent, and transform; ocean plate subduction; continent-continent convergence; seafloor spreading; and mantle convection. There is also a discussion of the layers and components of ocean crust (in relation to how it formed at seafloor spreading centers), and terrane accretion in subduction zones (as a way that continents grow).

**This video comes at the start of the semester. For a full playlist, refer to the Oceanography or Geology playlists on the Earth Rocks! YouTube Channel.

Content within this video is based on information available in any standard introductory college oceanography or geology textbook, such as Essentials of Oceanography -- Trujillo and Thurman -- OR Essentials of Geology -- Tarbuck and Lutgens -- Pearson Publishing.

i wish i could go back to school and be in your class. you make learning fun. All i had was a lame ass teacher who made me memorize a variety of peak tops names and their size in KM while i could never really remember anything because she said to every question 'jus because that is how it is' and i had to settle for that. ugh! such teachers should be kicked out

[albinbaby]

I'm a Geology student this channel definitely will help everyone to understand geology.. really informative appreciate you katryn for the great effort 🤍

[agimatproductions]

well explained it can be more interesting when it's on 3D? 4D?

[antoniovazquez]

Thank you very much for the explanation.

[muralidatla]

THANK U, SO MUCH INFORMATION PUT TOGETHER IN ONE VIDEO.THANK U SO MUCH.

Clearly we need to (determine) the puppeteers who claim to deliniate the region of the Asthenosphere. What form of geoAuthoritarianism do you submit t?

[monarch]

Wait, continental crust can’t subduct but continents can?

[msperryssciencecorner]

I don't believe this is really BASIC and definitely not to be used as an introduction to this material! Maybe for a college-level geology class, but my poor middle school Earth Science class was confused!

[mitsunori]

Perhaps too much detail is some of the diagrams.

[paulmasumba]

try it out pease the video is really amazing

[anjumdaisy]

plz yr snd me plate tectonic and types in urdu.

This is what two preeminent geophysicists have to say about convection.
MANTLE DYNAMICS AND PLATE KINEMATICS
Carlo Doglioni, La Sapienza University, Rome, Italy
Roberto Sabadini, University of Milan, Italy


". . . . . none of the proposed models of mantle convection can account for the simpler pattern in plate motion we observe at the surface, nor has a unique solution been proposed for how material in the mantle convects. At the moment there is no way to link mantle dynamics and plate kinematics at the surface, considering that the mantle and lithosphere are detached. The Atlantic and Indian ridges are in fact moving apart with respect to Africa, proving not to be fixed both relative to each other and relative to any fixed point in the mantle. This evidence confirms that ocean ridges are decoupled from the underlying mantle."

To see a geologic model that describes the Earth's geological processes to an unmatched level of accuracy go to;

Is Anyone watching from India in October 2024😊?

[Danstaafl]

Very well done. Too bad the convection theory is totally wrong..

[mitsunori]

rather messy and confusing. Diagrams of all shapes and sizes...

Holy Quran 27:88
And you see the mountains, thinking them rigid, while they will pass as the passing of clouds. [It is] the work of Allah, who perfected all things. Indeed, He is Acquainted with that which you do.This is the meaning of miracle. How Quran knows this 1400 years ago?

[r.i.pfreaks]

very confusing because in one pic many thinks are tough. First learn to teach

[jordanagius]

video sucks i'm only watching this because of school. should stop making content
