What layer of Earth are the tectonic plates found in?

Back

Lithosphere

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often causing one plate to be forced below the other.

During convection, what happens to less dense currents?

Back

They rise.

Why was Alfred Wegener's Continental Drift theory not well received initially?

Back

Scientists did not know the force responsible for moving the continents.

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often creating new crust.
