Plate Tectonics

Front

What is a continental rift valley and how is it formed?

Back

A continental rift valley is a lowland region formed by the stretching of continental crust at divergent plate boundaries.

Front

What type of plate boundary is the San Andreas Fault?

Back

The San Andreas Fault is a transform plate boundary.

Front

What is the thickest layer of the Earth?

Back

The mantle is the thickest layer of the Earth.

Front

What type of boundary created the Great Rift Valley in Africa?

Back

The Great Rift Valley was created by a divergent plate boundary.

Front

What is the composition of the Earth's inner core?

Back

The inner core is composed of solid iron and nickel.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are divergent, convergent, and transform.

Front

What geological features are commonly associated with divergent boundaries?

Back

Geological features commonly associated with divergent boundaries include rift valleys and mid-ocean ridges.

Front

What occurs at convergent plate boundaries?

Back

At convergent plate boundaries, tectonic plates move towards each other, often resulting in subduction, mountain building, or volcanic activity.

Front

What is subduction and where does it occur?

Back

Subduction is the process where one tectonic plate moves under another and is forced into the mantle, occurring at convergent boundaries.

Front

What is the role of the asthenosphere in plate tectonics?

Back

The asthenosphere is a semi-fluid layer of the mantle that allows tectonic plates to move.
