Plate Boundaries

Front

What happens where an oceanic plate converges with a continental plate?

Back

The denser oceanic plate slides under the less dense continental plate.

Front

What geological feature forms as a result of divergent boundaries?

Back

Rift valleys, like the Great African Rift Valley.

Front

What type of plate boundary is indicated by the formation of a rift valley?

Back

Divergent boundary.

Front

What is Pangaea?

Back

The name of the supercontinent that existed millions of years ago.

Front

What type of boundary occurs where two plates move together, causing one plate to descend into the mantle beneath the other?

Front

What is a transform boundary?

Back

A plate boundary where two plates slide past each other horizontally.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What geological activity is commonly associated with convergent boundaries?

Back

Earthquakes and volcanic eruptions.

Front

What is the main characteristic of divergent boundaries?

Back

Plates move apart, creating new crust as magma rises.

Front

What is continental drift?

Back

The theory that continents have moved over geological time and were once joined together.
