Plate Boundaries

Front

What are the two crustal features that occur near every subduction zone?

Back

Volcanoes and Trenches

Front

What type of boundary occurs when two plates slide past each other?

Back

Transform Boundary

Front

Which type of crust will subduct if two plates converge?

Back

Oceanic Crust

Front

What is the process called that creates new crust at a divergent oceanic boundary?

Back

Seafloor Spreading

Front

What are huge pieces of lithosphere that move on the asthenosphere called?

Back

Tectonic Plates

Front

What is a convergent boundary?

Back

A boundary where two plates move towards each other, often causing one plate to subduct beneath the other.

Front

What is a divergent boundary?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle on which tectonic plates float.

Front

What geological feature is formed at a transform boundary?

Back

Fault lines, such as the San Andreas Fault.

Front

What happens to oceanic crust at a subduction zone?

Back

It is forced down into the mantle beneath a second plate.
