What is subduction?

Back

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

Front

What is a plate boundary?

Back

A plate boundary is the region where two tectonic plates meet.

Front

What do oceanic and continental convergent plate boundaries form?

Back

They form deep-oceanic trenches and volcanoes.

Front

What type of plate boundary is characterized by plates sliding past each other?

Back

Transform boundary.

Front

What is a hot spot?

Back

A hot spot is a volcanically active area of the Earth's surface far from a tectonic plate boundary.

Front

What is a fault?

Back

A fault is a fracture or zone of fractures between two blocks of rock.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What occurs at divergent plate boundaries?

Back

At divergent plate boundaries, tectonic plates move apart, leading to the formation of new crust.

Front

What is the result of convergent plate boundaries?

Back

Convergent plate boundaries can result in mountains, volcanoes, and deep ocean trenches.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is created at mid-ocean ridges.
