As part of the water cycle, water from Earth’s surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• evaporation → condensation → precipitation

• precipitation → condensation → evaporation

• condensation → evaporation → precipitation

• evaporation → precipitation → condensation

What would most likely happen if all evaporation of water stopped?

• Runoff would increase.

• More clouds would form.

• No precipitation would fall.

• Moist air would be in the atmosphere.

A student examines the processes of evaporation and condensation in the water cycle by filling a beaker with water and covering the beaker with a glass lid. She positions a lamp so that its light shines on the beaker, as shown in the image. The student finds that condensation did not significantly collect on the glass lid. What change should the student make in the design process to make her results more accurate?

• Remove the lid and leave the beaker open to the light from lamp.

• Remove the lid and cover the beaker with a dark cloth.

• Turn the lid over and place some ice cubes on it.

• Turn the lid over and pour some warm water on it.

The diagram shows various stages of the water cycle labeled P, Q, R, and S.

Which statement about the stages of the water cycle is correct?

• Stage P is evaporation, which occurs immediately after stage Q, which shows condensation.

• Stage Q is condensation, which occurs immediately after stage P, which shows evaporation.

• Stage R is evaporation, which occurs immediately before stage S, which shows precipitation.

• Stage Q is condensation, which occurs immediately before stage P, which shows precipitation.

Where does the greatest atmospheric pressure occur?

• Mesosphere

• Stratosphere

• Thermosphere

• Troposphere

Air pressure changes across the different layers of the atmosphere. Which option sequences the atmosphere's layers in increasing order of atmospheric pressure?

• troposphere, stratosphere, mesosphere, thermosphere, exosphere

• troposphere, stratosphere, thermosphere, mesosphere, exosphere

• exosphere, mesosphere, thermosphere, stratosphere, troposphere

• exosphere, thermosphere, mesosphere, stratosphere, troposphere

What is one example of how humans impact global warming?

• Contour plowing by farmers increases the level of rain water run-off.

• Burning coal and oil increases the level of carbon dioxide in the atmosphere.

• The use of copper wire in power transformers increases the speed of the electrical currents.

• Heat emitted from factories, automobiles, and buildings increases the average global temperature.

With less than 5% of the world's population, the United States emits 24% of the world's carbon emissions, while China with 20% of the world's population accounts for 12% of the world's carbon emissions. Based upon this information, what can be inferred about the impact of human population growth on global warming?

• Global warming will decrease as the human population increases.

• An increase in human population results in an increase in carbon emissions.

• There is a direct link between the expanding population and the increase in global warming.

• It is the types of human activities that contribute the most to global warming not just the expanding population.

Volcanic eruptions cause the release of gases such as carbon dioxide, hydrogen sulfide, water vapor, and sulfur dioxide along with soot, ashes, and dust. What is a direct consequence of volcanic eruptions?

• increase in the concentration of greenhouse gases

• decrease in the level of oxygen in the air

• increase in percent of oxygen in the air

• decrease in rainfall

What is the densest layer of the earth?

• Crust

• Mantle

• Inner core

• Outer core
