Plate Boundary Review

Front

Divergent Plate Boundary

Back

A tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

Transform Plate Boundary

Back

A tectonic plate boundary where two plates slide past each other horizontally, causing earthquakes.

Front

Subduction

Back

The process where one tectonic plate moves under another, often leading to volcanic activity.

Front

Rift Valley

Back

A lowland region formed by the divergence of tectonic plates, often associated with volcanic activity.

Front

Convergent Plate Boundary

Back

A tectonic plate boundary where two plates move toward each other, often resulting in mountain formation or subduction.

Front

Plate Tectonics

Back

The scientific theory that describes the large-scale movement of Earth's lithosphere, which is divided into tectonic plates.

Front

Earthquake

Back

A sudden release of energy in the Earth's crust that creates seismic waves, often occurring at plate boundaries.

Front

Volcano

Back

An opening in the Earth's crust through which molten lava, ash, and gases are expelled, often found at convergent or divergent boundaries.

Front

Seafloor Spreading

Back

The process by which new oceanic crust is formed at divergent boundaries, leading to the expansion of ocean basins.

Front

Fault Line

Back

A fracture in the Earth's crust along which movement has occurred, commonly found at transform boundaries.
