SRG 2 Geology

Front

What are the layers of the Earth in order from the surface?

Back

Crust, Mantle, Outer Core, Inner Core

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where two tectonic plates are moving apart.

Front

What type of plate boundary creates mountains?

Back

Convergent boundaries create mountains when two tectonic plates collide.

Front

What happens to the density of a blob of material as it loses heat?

Back

As it loses heat, the material becomes slower and more dense, causing it to sink.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases) due to differences in density.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to the formation of mountains, trenches, or volcanic activity.

Front

What is the role of convection currents in the Earth's mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates on the Earth's surface.

Front

What geological features are formed at divergent boundaries?

Back

Divergent boundaries can create rift valleys and mid-ocean ridges.

Front

What is the significance of the Earth's crust?

Back

The Earth's crust is the outermost layer and is where we live; it contains the continents and ocean floors.
