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

Back

Uneven heating and the rotation of Earth.

Front

How do land and water differ in terms of heating and cooling?

Back

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

Front

What is the effect of Earth's rotation on wind direction in the Northern Hemisphere?

Back

Winds shift in a clockwise direction due to the rotation of Earth.

Front

What process creates winds in our atmosphere?

Back

Winds are created as a result of uneven heating of the air in the atmosphere.

Front

Define 'uneven heating' in the context of Earth's atmosphere.

Back

Uneven heating refers to the variation in temperature caused by the Sun's energy being distributed unevenly across the Earth's surface.

Front

What role does the Sun play in the water cycle?

Back

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

Front

Explain how the rotation of Earth affects ocean currents.

Back

The rotation of Earth causes ocean currents to curve, a phenomenon known as the Coriolis effect.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, due to Earth's rotation.

Front

How does the density of air affect wind patterns?

Back

Differences in air density, caused by uneven heating, lead to variations in air pressure, which drive wind patterns.
