Plate Boundaries Review

Front

What type of crust will subduct if two plates converge?

Back

Oceanic crust subducts when two plates converge.

Front

What occurs because of convection currents in the Earth's mantle?

Back

Tectonic plates on the crust move due to convection currents.

Front

What is the type of crust primarily made up of basalt and found at the bottom of the oceans?

Back

Oceanic Crust.

Front

What geological feature is created when two continental plates collide?

Back

Mountains are created when two continental plates collide.

Front

Where does new crust form?

Back

New crust forms along a divergent boundary.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, and new crust is formed.

Front

What is a subduction zone?

Back

A subduction zone is where one tectonic plate moves under another and sinks into the mantle.

Front

What is the primary difference between oceanic and continental crust?

Back

Oceanic crust is denser and primarily made of basalt, while continental crust is less dense and primarily made of granite.

Front

What geological activity is commonly associated with convergent boundaries?

Back

Earthquakes and volcanic activity are commonly associated with convergent boundaries.
