Convection
1 Convection occurs in fluids. Fluids are liquids and gases.
2 When a fluid is heated it expands. The fluid becomes less dense and rises.
3 The warm fluid is replaced by cooler, denser fluid. The resulting convection current transfers energy throughout the fluid.
4 Convection currents can be on a very small scale, such as heating water in a beaker or on a very large scale, such as heating the air above land and sea. Convection currents are responsible for onshore and offshore breezes.
