8.10A The Sun's Energy

Front

What is the primary source of energy that drives weather patterns on Earth?

Back

The Sun's energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

How does the Sun's energy affect wind patterns on Earth?

Back

The Sun's energy causes uneven heating of the Earth's surface, leading to differences in air pressure and the generation of wind.

Front

What is the effect of blocking solar radiation on Earth's weather?

Back

Blocking solar radiation would remove the source of energy that drives convection, thus stopping wind generation.

Front

What is an example of heat transfer by convection?

Back

An illustration of heat being transferred by wind.

Front

What causes the generation of wind in the atmosphere?

Back

Wind is generated by the uneven heating of the air in the atmosphere.

Front

What are the major patterns of movement of air and water on Earth influenced by?

Back

Uneven heating and the rotation of Earth.

Front

What happens to air when it is heated?

Back

Heated air becomes less dense and rises, creating convection currents.

Front

What role does the Sun play in the water cycle?

Back

The Sun's energy causes evaporation of water, which is a key process in the water cycle.

Front

What is the relationship between air density and wind?

Back

Differences in air density, caused by uneven heating, lead to changes in air pressure, which results in wind.
