Convection and The Mantle

Front

What is a convection current?

Back

A convection current is the flow that transfers heat within a fluid.

Front

What is density?

Back

Density is a measure of how much mass there is in a volume of substance.

Front

What is conduction?

Back

Conduction is the heat transfer within a material or between materials that are touching.

Front

What is radiation?

Back

Radiation is the transfer of energy through space.

Front

What is heat transfer?

Back

Heat transfer is the movement of energy from a warmer object to a cooler object.

Front

What is the role of the mantle in convection?

Back

The mantle is a layer of the Earth where convection currents occur, transferring heat from the Earth's core to the surface.

Front

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.

Front

Can you give an example of convection?

Back

An example of convection is boiling water, where hot water rises and cooler water sinks.

Front

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

Back

Convection currents in the Earth's mantle drive plate tectonics and influence geological activity.
