7.10 A&B - Plate Tectonics

Front

What is a divergent boundary?

Back

A divergent boundary is 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.

Front

What land feature is formed directly over a subduction zone?

Back

A trench is formed directly over a subduction zone, where one tectonic plate is being forced under another.

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally, causing earthquakes.

Front

What landforms are created when two continental plates collide?

Back

Mountain ranges are formed when two continental plates collide.

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 convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often leading to the formation of mountains or trenches.

Front

What is the San Andreas Fault an example of?

Back

The San Andreas Fault is an example of a transform boundary.

Front

What happens at a mid-ocean ridge?

Back

At a mid-ocean ridge, tectonic plates are diverging, and magma rises to create new oceanic crust.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often characterized by steep walls.

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates can cause earthquakes when they move and interact at their boundaries, especially at transform boundaries.
