Front

Continental Crust

Back

crust under the continent. Felsic. Less dense, thicker part of the lithosphere.

Front

Convection Currents

Back

Transfer of energy where warmer, less dense material rises, cools, and sinks back down, creating a cycle; driving force of crust movement.

Front

Convergent boundary

Back

A type of tectonic plate boundary where two plates come together, and the denser plate subducts.

Front

Subduction

Back

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

Front

Continental-Oceanic Convergent Boundary

Back

Occurs when an oceanic plate converges with a continental plate, leading to subduction of the oceanic plate.

Front

Oceanic-Oceanic Convergent Boundary

Back

Occurs when two oceanic plates converge, often forming a trench and volcanic islands.

Front

Continental-Continental Convergent Boundary

Back

Occurs when two continental plates converge, leading to the formation of mountain ranges.

Front

Volcanic Arc

Back

A chain of volcanoes formed above a subducting plate, often associated with convergent boundaries.

Front

Oceanic Trench

Back

A deep underwater trench formed at an oceanic-oceanic convergent boundary.

Front

Lithosphere

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.
