The air in the atmosphere is a poor conductor of energy. Which of the following incorrectly describes how the atmosphere is affected by conduction?
Most of the energy transfer by conduction occurs right at Earth’s surface.
At night, the ground cools and conducts heat away from the air close to the ground.
Air molecules in the atmosphere are heated which causes the atmosphere to vibrate.
During the day, solar radiation heats the ground, which heats the air close to the ground.
Which layer of the atmosphere is correctly paired with its characteristics?
The stratosphere is the layer of the atmosphere that contains ozone that protects living things from ultraviolet radiation.
The mesosphere is the layer of the atmosphere in which thin, feathery clouds of ice form due to its cold temperatures.
The thermosphere is the layer of the atmosphere that has no definite outer limit and protects the surface from being hit by meteoroids.
The troposphere is the layer of the atmosphere that contains the ionosphere where weather occurs.
The Sun heats the atmosphere of Earth unevenly. Which of the following statements is the most likely result of this uneven heating?
Convection in the atmosphere causes a change in air density, resulting in winds.
Conduction through the atmosphere causes evaporation to occur over oceans, resulting in rain.
Radiation from the Sun reflects through the atmosphere back into space resulting in cooler evenings.
Radiation from the Sun causes atmospheric moisture to collect over mountain ranges resulting in snowfall.

The heat from the fire can be felt on all sides.
Where do we see convection in a pot of boiling water on the stove?
The water heats up by touching the hot, metal pot.
The steam from the hot water rises out of the pot.
The heat from the fire can be felt on all sides.
Where do we see conduction in a pot of boiling water on the stove?

None of these are correct
What kind of breeze is this and when would it form?
Land breeze - daytime
Land breeze - nighttime
Sea breeze - daytime
Sea breeze - nighttime
Why do land breezes occur at night?
Land cools off slower than water, so the air above water is cooler.
Water cools off faster than land, so the air above land is warmer.
Land heats up slower than water, so the air stays cooler during the day.
Water cools off slower than land, so the air above water is warmer.
