Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Define convection.

Back

Convection is the transfer of heat in fluids (liquids and gases) through the movement of the fluid itself, where warmer areas rise and cooler areas sink.

Front

Give an example of convection.

Back

An example of convection is warm air rising above a heater, causing cooler air to move in and create a circulation.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What causes convection currents in the atmosphere?

Back

Convection currents in the atmosphere are caused by the uneven heating of the Earth's surface, leading to warm air rising and cool air sinking.

How does convection affect weather patterns?

Back

Convection affects weather patterns by creating wind and influencing cloud formation and precipitation.
