1. Water cycles from the atmosphere into the hydrosphere through precipitation. Water cycles
from the hydrosphere back to the atmosphere through evaporation.
Which of the following is one way that these patterns can effect climate?
Areas located near a large body of water typically receive more precipitation than areas
A. that are not located near water.
Areas that are located near fault lines typically have more earthquakes than areas that are
B. not located near fault lines.
C.
Areas that have high latitudes are typically colder than areas that have lower latitudes.
Areas located near the equator are typically warmer than areas that are not located near the
D. equator.
2. Which component of the Earth includes the water above, on, or in the Earth's crust? (This
includes water in the oceans, seas, lakes, ground water, and atmospheric moisture.)
A. lithosphere
B. biosphere
C. hydrosphere
D. atmosphere
3. The term air pressure is used to refer to the weight of the atmosphere pressing down on the
Earth's surface. What creates air pressure?
A.
B.
C.
D.
the magnetic field of the Earth attracting air molecules to the planet's surface
the rotation of the Earth pushing air molecules against the planet's surface
the force of gravity pulling air molecules toward the Earth's surface
the weight of space pressing against the top of the Earth's atmosphere
4. Farmers often must add fertilizer to soil that is deficient in nutrients. Which statement best
describes an effect that this might have?
A. The fertilizer could make the soil too fertile to grow crops.
B. The fertilizer could kill useful insects.
C. The fertilizer could runoff and pollute nearby water sources.
D. The fertilizer could cause crops to release pollution into the air.
5. Which of the following cycles tracks the movement of water in the hydrosphere?
A. the hydrogen cycle
B. the nitrogen cycle
C. the rock cycle
D. the hydrologic cycle
6. Water can move from the hydrosphere to the _______ through the process of evaporation.
A. cryosphere
B. biosphere
C. lithosphere
D. atmosphere
7. Many different processes, both natural and human-caused, can release carbon dioxide into the
atmosphere. Which of the following processes can occur naturally and adds carbon dioxide to the
atmosphere?
A. the burning of coal in a coal-fired power plant
B. the burning of natural gas on a stove
C. the burning of plant life in a forest fire
D. the burning of petroleum in an automobile
8. The atmosphere is made up of several layers of air. The bottom two layers are the troposphere
and the stratosphere. How does the troposphere differ from the stratosphere?
A.
B.
C.
D.
The troposphere contains more ozone molecules than the stratosphere.
The troposphere is much warmer than the stratosphere.
The troposphere contains less moisture than the stratosphere.
The troposphere has a lower air pressure than the stratosphere.
9. The diagram below shows incoming energy from the Sun. The red arrows represent different
paths that the incoming radiation might follow.
What holds the Sun's energy close to Earth and keeps the Earth warm?
A. carbon dioxide and water vapor in the atmosphere
B. a magnetic field that surrounds the Earth
C. nitrogen and hydrogen gases in the atmosphere
D. gravitational pull on the heat molecules
10. Over the past 60 years, the level of carbon dioxide in the atmosphere has been continually
increasing. Many scientists hypothesize that this increase has led to an imbalance in the carbon
cycle and a climatic trend known as global warming.
In which of the following ways could humans help the carbon cycle return to normal?
A. reduce the amount of fossil fuels they combust
B. cut down trees and other large plants that depend on carbon dioxide
C. pump nitrogen and oxygen into the air to help rebalance the atmosphere
D. cap volcanoes so that they do not release more carbon dioxide
11. The location of ozone in the atmosphere determines whether it is “good” or “bad.” Which of
the following statements about ozone is true?
A. Ozone in the troposphere is harmful, and ozone in the stratosphere is beneficial.
B. Ozone in both the troposphere and the stratosphere is bad.
C. Ozone in the stratosphere is harmful, and ozone in the troposphere is beneficial.
D. Ozone in both the troposphere and the stratosphere is good.
12. The Earth’s atmosphere consists of a combination of gases. Scientists believe that we are
creating air pollution, which causes an increase in some gases, such as carbon dioxide. Such
increases make it difficult for the atmosphere to stay in balance, and heat radiating from the
Earth is being trapped. What term refers to the sun’s energy being trapped in our atmosphere?
A. transpiration
B. convection
C. cumulus clouds
D. greenhouse effect
13. In all areas of the world, groundwater is an important source of drinking water. However, in
many areas, the groundwater is being polluted, mainly by nitrates. Sometimes the groundwater is
so polluted, it is no longer able to be used as drinking water. What is the most likely source of
the nitrate pollutants?
A. use of organic fertilizers (manure) in farming
B. too many weeds growing near bodies of water
C. litter in the form of plastic bottles and aluminum cans
D. the abundance of apartment complexes in urban areas
