1. the density of gas particles in a section of earth's atmosphere decreases. which of the following is the most likely explanation for this event?

the air pressure in that section of earth's atmosphere decreased.

the air pressure in that section of earth's atmosphere increased.

the total number of gas particles in earth's atmosphere decreased.

the total number of gas particles in earth's atmosphere increased.

2. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere?

it contains gases that living organisms breathe.

it contains gases that trap incoming solar radiation.

it provides a medium for cycles that provide nutrients to living organisms.

it provides a medium for water to move between earth's surface and the air.

3. which of the following is considered a benefit to using wind energy as a source of power?

winds blow consistently.

wind energy does not pollute.

wind turbines require very little land to construct.

winds produce higher quality energy than other sources.

4. as a barometer lowers, what kind of weather can be expected?

there will likely be no change in the weather.

the weather will likely become clearer and drier.

the weather will likely become cloudier and stormier.

the weather will likely become cooler and less humid.

5. which of the following do meteorologists not typically use weather balloons to record?

atmospheric pressure

cloud types

humidity

temperature

6. during which step in the can crush lab did the air pressure outside the can become greater than the pressure inside the can?

the can was filled nearly to the top with water.

the can was placed on the hot stove burner for several minutes.

the can was removed from the hot oven burner.

the can was placed upside-down in the water-filled pan.

7. water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. as the molecules travel away from the equator, which step in the water cycle is most likely to happen next?

diagram of a globe showing a water molecule moving north away from the equator. (see picture).

the molecules cool and eventually form clouds.

the molecules freeze and eventually form ice crystals.

the molecules heat up and eventually form water vapor.

the molecules break apart and eventually form precipitation.

8. as an airplane rises through the atmosphere, machines cause the pressure inside the cabin to decrease. as the airplane descends toward earth, machines cause the pressure inside the cabin to increase. based on your observations from the can crush lab, explain why these changes in pressure are necessary.

9. where on earth's surface might you be if you are experiencing the trade winds? explain how air pressure, temperature, and the coriolis effect influence the movement and direction of these winds.
