Convection currents in the Earth's mantle are caused by:

• Less dense hot magma moving downward

• Less dense hot magma moving upward

• Tectonic plate movement

• More dense cooler magma moving upward

Which conditions would be favorable to create a convection current?

• two masses of cold air near each other

• two masses of air at the same temperature next to each other

• a mass of cold air near a mass of warm air

• two masses of warm air near each other

Convection Current

• A circular motion of air that causes wind and changes in weather

• The transfer of energy by electromagnetic waves.

• A type of heat transfer that occurs through the movement of fluids.

• The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.

How does heat transfer by convection occur?

• Heat is transferred through empty space.

• Heat is transferred through the vibration of particles in a solid.

• Heat is transferred by the movement of heated fluid from one place to another.

• Heat is transferred by the emission of infrared radiation.
