8.10A The Sun's Energy

Front

What causes the major patterns of movement of air and water on Earth?

Back

Uneven heating and the rotation of Earth.

Front

What is convection?

Back

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

Front

What is an example of heat transfer by convection?

Back

An illustration of heat being transferred by wind.

Front

What creates a sea breeze?

Back

During the day, the Sun’s energy heats up the land faster than the water, causing the air above the land to warm and rise, creating a convection current.

Front

What is the most important factor that creates wind patterns at the shore?

Back

The air above the land heats up and cools off more quickly than the air over the water.

Front

In which states of matter does convection occur?

Back

Convection occurs in liquids and gases.

Front

What is the role of the Sun's energy in weather patterns?

Back

The Sun's energy heats the Earth's surface unevenly, leading to air movement and weather patterns.

Front

How does the rotation of Earth affect wind patterns?

Back

The rotation of Earth causes the Coriolis effect, which influences the direction of wind and ocean currents.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What happens to air pressure when the air above the land heats up?

Back

The air expands, becomes less dense, and rises, leading to lower air pressure.
