Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

What is a Divergent Boundary?

Back

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

What is a Convergent Boundary?

Back

A tectonic plate boundary where two plates move towards each other, often resulting in one plate being forced beneath another, leading to subduction.

What landform is commonly associated with Convergent Boundaries?

Back

Mountains or volcanic arcs.

Front

What is a Transform Boundary?

Back

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

Front

What is the Great Rift Valley?

Back

A large-scale rift formed by divergent tectonic activity, located in East Africa.

What is Subduction?

Back

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

What is a Mid-Ocean Ridge?

Back

An underwater mountain range formed by divergent tectonic plates, where new oceanic crust is created.
