The Sun warms the atmosphere and drives convection currents because

• warm air is less dense and rises

• warm air is less dense and sinks

• warm air is more dense and rises

• warm air is more dense and sinks

Why does the Earth experience unequal heating?

• The oceans are not equally distributed around the Earth.

• The Earth's revolution brings it closer to the Sun at certain points during the year.

Which of the following is true about the heating of land and water?

• During the day, the Sun's energy heats up the land faster, which makes the air above it warmer.

• During the day, the Sun's energy heats up the water faster, which makes the air above it warmer.

• At night, the land cools off slower, making the air above it warmer.

• At night, the water cools off slower, making the air above it cooler.

Why is the Equator warmest?

• Because it is closest to the sun.

• Because it receives the most direct sunlight

• Because no clouds form here.

• Because it is far from the sun
