8th Science Plate Tectonics

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, where the Earth's crust is being pulled apart.

Front

What type of tectonic activity forms rift valleys?

Back

Rift valleys form where two plates move away from each other.

Front

What type of plate boundary is associated with folded mountains?

Back

Folded mountains form at convergent boundaries where two continental plates collide.

Front

What is a transform fault?

Back

A transform fault is a type of fault where two tectonic plates slide past each other horizontally.

Front

What is the asthenosphere?

Back

The asthenosphere is the soft layer of the mantle located between the lithosphere and the outer core.

Front

What type of boundary creates the Great Rift Valley and the Mid-Ocean Ridge?

Back

These features are created by divergent boundaries.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates collide, which can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is the lithosphere?

Back

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

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate is being forced under another, often leading to volcanic activity.

Front

What is the difference between a divergent and a convergent boundary?

Back

A divergent boundary occurs where plates move apart, while a convergent boundary occurs where plates collide.
