Plate Tectonics Flashcard

Front

What are the three types of plate boundaries?

Back

Divergent boundaries, convergent boundaries, and transform boundaries

Front

Which type of plate boundary occurs when two plates move away from each other?

Back

Divergent plate boundary

Front

What is the process called when two oceanic plates collide and one is forced beneath the other?

Back

subduction

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener

Front

What evidence did Alfred Wegener use to support the theory of continental drift? Options: fit of the continents, matching fossil evidence, and similar rock formations, climate patterns, ocean currents, and plate tectonics, oceanic trenches, volcanic activity, and mountain ranges

Front

What is seafloor spreading?

Back

The process of forming new oceanic crust through volcanic activity and its movement away from the mid-ocean ridge.

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Earth's mantle

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate is forced underneath another plate into the Earth's mantle.

Front

Which type of plate boundary is responsible for the formation of mountains?

Back

convergent

Front

What happens when two continental plates collide?

Back

Mountains are formed.
