Plate Boundary/Tectonics

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is a type of boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, leading to one plate being forced below another, which can create mountains or volcanic activity.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing earthquakes along faults.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the Earth's mantle that lies beneath the lithosphere, allowing tectonic plates to move.

Front

What forms at a convergent boundary between a continental plate and an oceanic plate?

Back

Volcanoes are formed at a convergent boundary between a continental plate and an oceanic plate.

Front

What is the Himalayan mountain range an example of?

Back

The Himalayan mountain range is an example of a continent-continent convergent boundary.

Front

What is subduction?

Back

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

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates are moving apart, often associated with divergent boundaries.

Front

What are mid-ocean ridges?

Back

Mid-ocean ridges are underwater mountain ranges formed by the upwelling of magma at divergent plate boundaries.

Front

What is the lithosphere?

Back

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