 In the paragraph below, CHOOSE THE THREE words that name the processes in which water vapor enters the atmosphere.

The sun causes evaporation by heating water molecules until they speed up and spread out, entering the air as water vapor. Plants take in water through their roots, and it moves up the stem and into the leaves. Transpiration then occurs. Animals, including people, breathe out or exhale in the process of respiration. 

• Respiration

• Transpiration

• Evaporation

• Speed

Michael was watching the rain hit the sidewalk in front of his house. After a few minutes, he noticed a change in the precipitation and saw that the precipitation had changed into ice pellets.

• falling

• rising

• warming

• stable

Ethan watched the news one evening. During the weather section, the meteorologist said a cold front was moving in and then showed a picture of the front. How will these two air masses interact, and what kind of weather will they bring?

• The warm air rises above the heavier cold air and this front brings clear skies.

• The warm air rises above the heavier cold air and this front brings severe weather.

• The cold air rises above the heavier warm air and this front brings light rain.

• The cold air slides under the warm air and the front becomes occluded.

How has technology changed weather forecasting for meteorologists?

• Forecasts have not changed because of technology.

• Forecasts have improved because technology changes the weather.

• Forecasts have improved because technology provides more information.

• Forecasts have not changed because technology prevents meteorologists from making observations.

Lamar lives along the eastern coast of the United States, where the Gulf Stream influences

the temperatures.

What is the relationship between air masses and ocean currents?

• Warm air masses warm the ocean currents.

• Cold air masses cool the ocean currents. 

• Warm ocean currents cool the air masses above them.

• Warm ocean currents warm the air masses above them.

If the Gulf Stream cooled, what would happen to the climate?

• The weather along the east coast would be cooler, because a cooling

  Gulf Stream would cause the air masses above it to cool.

• This would affect air

  temperatures, making them colder, and would cause changes in wind speed

  and wind direction because the air masses would interact differently if they

  were cold.

• Cold air holds less moisture, so precipitation would change.

• All of the above.
