7.E.1 test review

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• A. The troposphere produces the ozone layer.

• B. The troposphere has the highest temperatures.

• C. The troposphere contains a highest amount of gas particles above it.

• D. The troposphere is the region in which weather occurs.

Answer explanation

The troposphere is the region in which weather occurs, leading to the greatest amount of atmospheric pressure compared to other layers.

Which diagram correctly represents a cold front and the air mass movements associated with cold fronts?

• Diagram A

• Diagram B

• Diagram C

• Diagram D

Answer explanation

Diagram A correctly represents a cold front and the associated air mass movements, making it the correct choice.

The circle on the map represents the area where an air mass formed over Canada. Which characteristics best describe the weather conditions that can be predicted to occur when this air mass moves into the United States?

• Warm and dry weather conditions

• Warm and moist weather conditions

• Cold and dry weather conditions

• Cold and moist weather conditions

Answer explanation

When an air mass forms over Canada, it is likely to bring cold and dry weather conditions when it moves into the United States.

Which gas is represented by Gas #1 within the pie chart?

• carbon dioxide (CO2)

• argon (Ar)

• nitrogen (N2)

• oxygen (O2)

Answer explanation

Gas #1 in the pie chart represents oxygen (O2), making it the correct choice.

Which stage of the water cycle would most directly cause the weather conditions shown in eastern Texas?

• condensation

• evaporation

• precipitation

• infiltration

Answer explanation

Evaporation is the stage of the water cycle that would most directly cause the weather conditions in eastern Texas by leading to the formation of clouds and subsequent precipitation.

Which of the following is most likely the best conditions to have the greatest amount of transpiration and evaporation to occur within the water cycle?

• The greatest amount of transpiration and evaporation will occur when the air temperature is low and the humidity is low.

• The greatest amount of transpiration and evaporation will occur when air temperature is low and the humidity is high.

• The greatest amount of transpiration and evaporation will occur when the temperature is high and the humidity is low.

• The greatest amount of transpiration and evaporation will occur when the air temperature is high and the humidity is high.

Answer explanation

The greatest amount of transpiration and evaporation will occur when the temperature is high and the humidity is low.

What is the most likely cause of the high and low pressure systems shown on the weather map of the United States?

• Lunar gravity causes high and low pressure systems due to the push and pull forces on Earth's atmosphere.

• Global warming causes high and low pressure systems due to the melting of Earth's polar ice caps.

• The Coriolis effect causes high and low pressure systems due to the wind patterns on Earth.

• Solar energy causes high and low pressure systems due to the patterns of heating and cooling over large areas of the Earth’s surface.

Answer explanation

The Coriolis effect causes high and low pressure systems due to the wind patterns on Earth.

Use the below barometric pressure graph to answer the question: At what time did the barometric pressure start to increase significantly?

• A) between 6 A.M. and 7 A.M.

• B) between 8 A.M. and 9 A.M.

• C) between 10 A.M. and 11 A.M.

• D) between 12 P.M. and 1 P.M.

Answer explanation

The barometric pressure started to increase significantly between 8 A.M. and 9 A.M., as shown on the graph.

Based on the map provided, which type of weather was Atlanta, Georgia most likely experiencing on January 7th, 2014?

• Warm rainy weather due to moist air from the Gulf of Mexico

• Very cold weather due to dry air from Canada

• Warm weather due to warm air from the Pacific Ocean

• Very warm weather due to cold dry air from Canada

Answer explanation

Based on the map, Atlanta, Georgia was most likely experiencing warm rainy weather on January 7th, 2014 due to moist air from the Gulf of Mexico.

Which set of changes in ozone levels would cause the most health concerns?

• An increase in both atmospheric and ground level ozone

• A decrease in both atmospheric and ground level ozone

• A decrease in atmospheric ozone and an increase in ground level ozone

• An increase in atmospheric ozone and a decrease in ground level ozone

Answer explanation

A decrease in atmospheric ozone and an increase in ground level ozone would cause the most health concerns due to increased exposure to harmful pollutants at ground level.
