Plate Tectonics Test Review

Front

What is subduction?

Back

Subduction is when an oceanic plate sinks beneath a continental plate.

Front

What type of plate boundary causes seafloor spreading?

Back

Divergent Boundary.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates collide, which can create folded mountains and volcanoes.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new oceanic crust.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What geological features are formed by convergent boundaries?

Back

Convergent boundaries can form mountains, volcanoes, and deep ocean trenches.

Front

What is the theory of continental drift?

Back

The theory of continental drift suggests that continents were once part of a single landmass and have since drifted apart.

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle that cause tectonic plates to move.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
