Air Currents and Unequal Heating of Earth

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.

• The Earth's axis is tilted.

• The atmosphere is not equally distributed around the Earth.

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

• seasons

• proximity to land

• underwater geography

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.

What has the highest albedo?

• the oceans

• Ice in the Arctic or Antarctic

• the ground

• roads

Albedo can best be described as...

• the temperature at the equator
• the amount of solar radiation absorbed
• the amount of solar radiation reflected
• the air pressure during El Nino
