Mid Ocean Ridge

Front

What are the two main types of plates that make up the Earth's surface?

Back

Continental and Oceanic Plates

Front

Why do earthquakes frequently occur in California and Japan?

Back

Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

Front

What happens at a Convergent Boundary when two continental plates collide?

Back

They crumple up and form mountains.

Front

What occurs at a Convergent Boundary when an oceanic plate meets a continental plate?

Back

Subduction occurs, leading to earthquakes and volcanoes.

Front

What is a Transform Boundary?

Back

A boundary where two plates slide past each other.

Front

What is the primary cause of plate tectonics?

Back

The movement of the Earth's lithosphere due to convection currents in the mantle.

Front

What is subduction?

Back

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

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
