What are the primary elements that make up the Earth's core?

Nickel and Iron.

Front

What is the theory of plate tectonics?

Back

The theory that Earth's outer shell is divided into several plates that glide over the mantle.

Front

What is a divergent boundary?

Back

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

Front

What is a transform boundary?

Back

A tectonic boundary where two plates slide past each other horizontally.

Front

What is subduction?

Back

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

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates.
