Earths Layers/Plate Tectonics/Pangea

Front

What are the three main layers of the Earth?

Back

The three main layers of the Earth are the crust, mantle, and core.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other, often causing one plate to be forced beneath the other.
