Plate Tectonics and Plate Boundaries

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other.

Front

Plates move away from one another at ___________ boundaries.

Back

Divergent boundaries.

Front

Where would the oldest rock be found?

Back

The oldest rock is typically found at the edges of tectonic plates, farthest from the mid-ocean ridges.

Front

The movement of the tectonic plates is caused by __________.

Back

Convection currents in the Asthenosphere.

Front

Mountains form from __________.

Back

The collision of tectonic plates.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other.

Front

What happens at transform boundaries?

Back

At transform boundaries, two tectonic plates slide past each other.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the Earth's mantle that allows tectonic plates to move.

Front

What is subduction?

Back

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

Front

What geological features are formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys are formed at divergent boundaries.
