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

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

A map of sea surface temperatures is provided. The patterns that are observed are due to the fact that

• the earth is wider at the equator, so this area spins faster than the poles.

• the equator receives more of the Sun's radiation than other parts of the Earth.

• the salt content is greater at the poles than at the equator.

• the warm, less dense water near the equator sinks, while the colder water rises.

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.

Ocean currents are the result of uneven heating of the water, which leads to

• conduction

• convection

• reflection

• condensation
