8.10A The Sun's Energy

Front

What is the main source of thermal energy that heats the Earth's atmosphere?

Back

The Sun.

Front

What happens to warm air in the atmosphere?

Back

Warm air is less dense, so it rises.

Front

What type of heat transfer occurs in liquids and gases?

Back

Convection.

Front

What is an example of heat transfer by convection?

Back

Heat being transferred by wind.

Front

What is the process called when warm air rises and cool air sinks?

Back

Convection currents.

Front

What drives the convection currents in the atmosphere?

Back

The Sun's energy.

Front

What is solar radiation?

Back

Energy emitted by the Sun in the form of light and heat.

Front

How does solar radiation affect wind generation?

Back

Solar radiation heats the Earth's surface, causing air to move and generate wind.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluids (liquids and gases).

Front

What role does the Sun play in the water cycle?

Back

The Sun provides energy for evaporation, which is a key process in the water cycle.
