F24 Flashcard #1

Front

What is the process of heat transfer between the Earth's core and mantle?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

Where is most of the volume in the Earth located?

Back

Most of the volume in the Earth is found in the mantle.

Front

What type of currents are formed in the mantle?

Back

Convection currents are formed in the mantle due to the heat from the core.

Front

What type of rock is primarily found on the ocean floor?

Back

Basalt rock is primarily found on the ocean floor.

Front

Which type of rock is denser and will subduct?

Back

Basalt is denser than granite and will subduct.

Front

Define convection in the context of geology.

Back

Convection is the transfer of heat through the movement of fluids, causing warmer, less dense material to rise and cooler, denser material to sink.

Front

What is the difference between basalt and granite?

Back

Basalt is a dark, fine-grained volcanic rock, while granite is a light-colored, coarse-grained igneous rock.

Front

Explain the role of the mantle in Earth's geology.

Back

The mantle plays a crucial role in tectonic activity and heat transfer within the Earth.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is the significance of convection currents in the mantle?

Back

Convection currents in the mantle drive plate tectonics and influence volcanic and earthquake activity.
