Afeni takes a video of pollen being blown off of a tree. Because she has been studying Earth’s spheres, she wants to determine which of the spheres are interacting in this scenario. Which of the following spheres is she observing?

• biosphere and atmosphere

• geosphere and atmosphere

• biosphere and hydrosphere

• atmosphere and hydrosphere

Aerosols are necessary for cloud forma,on and the scattering of sunlight. However, they come from different sources. The types of aerosols can also vary depending on a number of factors including geography and human involvement.

Consider Yosemite National Park and Los Angeles. Both are in California, but aerosols from both locations are different. Which statement below would BEST describe the difference in the aerosols in these two places?

• There should be more pollenin Los Angeles.

• There should be more dust particles in Los Angeles.

• There should be more soot particles in Los Angeles.

• There should be more sea salt particles in Los Angeles.

Scientists are studying a major forest fire that burned thousands of acres in California. Many trees and other plants were killed. Which of the following is MOST LIKELY to be a way in which the gases in the atmosphere are affected?

• . a decrease in the amount of oxygen released into the stratosphere by the trees the next year

• a decrease in the amount of oxygen released into the troposphere by the trees the next year

• . a decrease in the amount of carbon dioxide released into the stratosphere the next year

• a decrease in the amount of carbon dioxide released into the troposphere the next year

Meteorological data is collected daily to forecast weather and to compare it to the normal climate patterns. You’ll recall that weather is the state of the atmosphere at a given ,me and place, while climate is the pattern of weather over a long period of ,me. The table below shows meteorological data collected for a day in Washington, D.C. Which piece of data is related to climate?

• precipitation of 0.0 inches

• high temperature of 45°F

• average high temperature of 46°F

• . highest atmospheric pressure of 30.02 in Hg

In order to track the hole in the ozone, data needs to be collected from the ozone layer. Climatologists know that the ozone layer is about 25 km above the surface of Earth. What experiment design would collect the best data?

• . Sending a weather balloon to collect data into the stratosphere

• Flying an airplane with instruments to the top of the troposphere.

• . Sending a satellite into orbit with instruments in the thermosphere

• Launching a rocket through the atmosphere into the exosphere.

As you go up in altitude in the troposphere, the temperature decreases. Scientists name this phenomenon the environmental lapse rate. Below is a model that was created to predict how the environmental lapse rate would affect temperature when the temperature at sea level was 18°C.

Based on this data, which of the following statements is true about elevation and temperature?

• As you go up in altitude, the air temperature remains the same.

• As you go up in altitude, the air temperature consistently increases

• As you go up in altitude, the air temperature consistently decreases

• As you go up in altitude, the temperature slowly and gradually decreases

Based on the model above, if water vapor was in the air, at what altitude would it crystallize and freeze?

Note: 1 km = 1000 m

• 850 meters

• 1,250 meters

• 1,800 meters

• 2,400 meters
