ALFRED WEGENER AND PLATE TECTONICS

Front

What is the theory of continental drift?

Back

The theory proposed by Alfred Wegener that suggests continents were once joined together in a single landmass and have since drifted apart.

Front

What are the three main types of plate boundaries?

Back

Convergent, Divergent, and Transform.

Front

What geologic event is most commonly associated with transform boundaries?

Back

Earthquakes.

Front

What layer of the Earth contains convection currents?

Back

The mantle.

Front

What is the outermost layer of the Earth called?

Back

The crust.

Front

What happens at a convergent plate boundary?

Back

Plates move towards each other, often causing mountains to form or one plate to be subducted beneath another.

Front

What is a divergent boundary?

Back

A plate boundary where two plates move away from each other, often creating new crust as magma rises to the surface.
