What is convection?

Back

Convection is the transfer of heat by the movement of currents in a fluid (liquid or gas).

Front

What causes a land breeze?

Back

A land breeze occurs when cooler air from the land moves towards the sea, typically at night.

Front

What is the role of temperature in convection currents?

Back

Temperature differences create convection currents as warmer, less dense air rises and cooler, denser air sinks.
