Unequal heating of the Earth Atmosphere

What is the source of energy that heats our planet's atmosphere and oceans?

• the weather

• the wind

• the Sun

• the Earth's core

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.

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

• conduction

• convection

• reflection

• condensation

What is the primary or most important factor that influences climate?

• latitude

• longitude

• elevation

• climate zone

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 cause of uneven heating of Earth, which causes seasons is

• Earth's tilt

• Revolution

• Rotation

• Earth moves closer to the sun

Cold air sinks because it is less dense than warm air.

• True

• False

Cold air sinks because it is more dense than warm air.

• True

• False

Surface currents are created by

• wind (atmospheric circulation)

• seasons

• proximity to land

• underwater geography
