Convection Currents

Front

What are convection currents?

Back

Convection currents are the movement of fluid caused by the transfer of thermal energy, where warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What type of energy transfers in convection currents?

Back

Thermal/heat energy.

Front

What heats the air directly above the Earth?

Back

Conduction heats the air directly above the Earth.

Front

What creates wind?

Back

Wind is created when cool air moves in to replace warm air.

Front

How are ocean currents formed?

Back

Ocean currents are formed by less dense warmer water rising and more dense cold water sinking.

Front

From where do winds flow?

Back

Winds flow from high pressure to low pressure.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

What happens to warm air in convection?

Back

Warm air becomes less dense and rises.
