Front

Back

He had no proof of how the continents were moving.

Front

What is the thickest layer of the Earth?

Front

Front

What is the definition of plate tectonics?

Back

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

Front

What are the three main types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What occurs at a divergent boundary?

Back

Tectonic plates move apart, leading to the formation of new crust.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other.

Front

What geological features are commonly associated with convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.
