Plate Boundaries Practice

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide or move towards each other, often causing earthquakes and mountain formation.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move apart from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

Who developed the theory of continental drift?

Back

Alfred Wegener is credited with developing the theory of continental drift, which suggests that continents were once joined and have since drifted apart.

Front

What layer of the Earth is made up of tectonic plates?

Back

The crust is the outermost layer of the Earth and is made up of tectonic plates.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, one plate may be forced under another in a process called subduction, leading to volcanic activity and mountain building.

Front

What geological features are commonly formed at divergent boundaries?

Back

Divergent boundaries often lead to the formation of mid-ocean ridges and rift valleys.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic eruptions.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
