Front

What is subduction?

Back

The process where oceanic crust slides under another plate and is melted.

Front

What is the only event associated with all plate boundaries?

Back

Earthquakes.

Front

What are hotspots?

Back

Areas where hot mantle plumes push up through lithospheric plates to create volcanic islands, such as Hawaii.

Front

What is the only event associated with transform boundaries?

Back

Earthquakes.

Front

What is convection in the context of plate tectonics?

Back

The process in the upper mantle that helps move the lithospheric plates.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

Front

What are the three types of plate boundaries?

Back

Convergent, Divergent, and Transform boundaries.

Front

What happens at a convergent boundary?

Back

Two plates collide, which can lead to subduction or mountain formation.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move away from each other, often creating new crust.

Front

What is a transform boundary?

Back

A boundary where two plates slide past each other horizontally.
