Earthquakes.

Front

In which layer of the Earth do convection currents that move tectonic plates occur?

Back

Asthenosphere.

Front

What does the Theory of Plate Tectonics state?

Back

There are convection currents in the mantle that move the Earth’s tectonic plates.

Front

What is a convergent boundary?

Back

A plate boundary where two plates collide or move towards each other.

Front

What geological feature is commonly formed at divergent boundaries?

Back

Rift valleys and mid-ocean ridges.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another and is forced into the mantle.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is sea floor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust moves away.
