Heating the Atmosphere

If you went to the thermosphere, you would measure that the atmosphere molecules up there have a high temperature, but why would it feel cold to you?

• because the molecules are so few and far between

• because they are so far from earth's greenhouse gases

• because the gases are highly pressurized

• because this layer blocks gamma rays

When you feel heat from a bonfire, you are experiencing what type of energy transfer?

• Convective

• Radiant

Our atmosphere heats up by the same two kinds of energy transfer we identified in the campfire story: radiation and conduction.

• True

• False

Gases that can absorb infrared rays are called:

• Variable Gases

• Reusable Gases

• Constant Gases

• Greenhouse gases

Convection plays a large role in heating the atmosphere. Large amounts of heat and water vapor rise, riding along in the giant convection cell. When the air ______________, water vapor condenses into droplets of liquid water.

• cools

• heats

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

• conduction from the core

• meteors striking the ground

• comets striking the ocean

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
