Large sections of Earth's crust that move and interact.

Region where tectonic plates meet causing earthquakes and volcanoes.

A geologically stable region with minimal tectonic activity.

Deep depressions in the ocean floor where plates converge.

Underwater mountain range formed by diverging tectonic plates.

Evidence of past glaciers found in currently warm areas.

The theory that continents have moved over geological time.

Supercontinent that existed millions of years ago.

Earth consists of the crust, mantle, and core.

Heat generated inside Earth that drives tectonic activity.

The theory explaining the movement of Earth's plates.

Earth formed from dust, gas, and planetary collisions.

The semi-fluid layer of the Earth's mantle located beneath the lithosphere.

The underwater terrain including mountains, valleys, and ridges on the ocean floor.

The patterns of earthquake occurrences along tectonic plate boundaries.

Active volcanoes are primarily found along plate boundaries and hotspots.

Linear features on the seafloor where tectonic plates slide past each other.

Curved chains of volcanic islands formed at plate boundaries.

Places where two tectonic plates are moving apart, typically creating oceanic ridges.

Magma forms due to melting of the asthenosphere beneath divergent boundaries.

Divergent plate boundaries are often associated with earthquakes due to tectonic movement.

Underwater mountain ranges formed by volcanic activity at divergent plate boundaries.

At a divergent boundary, plates are moving away from each other.

The edges where two tectonic plates meet and interact.

A type of plate boundary where plates move apart, often creating new oceanic crust.

The process in which ocean basins form and expand due to tectonic activity.

Deep, narrow depressions in the ocean floor formed by converging tectonic plates.

The difference in sediment layers based on ocean floor age and activity.

A type of plate boundary where two tectonic plates slide past each other.

A major transform fault in California between the North American and Pacific plates.

The speed at which tectonic plates move, typically 1-15 cm/year.

A tectonic force caused by the elevation of mid-ocean ridges pushing plates apart.

A tectonic force where a denser oceanic plate subducts, pulling the rest of the plate along.

Some tectonic plates move faster due to forces like ridge push and slab pull.

Areas where one tectonic plate sinks beneath another, often leading to higher plate velocities.

Refers to changes in size of oceans due to tectonic plate movements.
