Look at the data regarding the cause for a decline in soil quality by sources around the world. Which source of degradation could be reduced by finding more efficient ways to heat homes?

• A. Agricultural activities

• B. Deforestation

• C. Industrialization

• D. Overuse of fuelwood

Which correctly identifies an example of a point source pollution and an example

of a nonpoint source pollution?

• Point: waste dumped from sewage plants; Nonpoint: oil spills

• Point: agricultural runoff; Nonpoint: acid rain

• Point: oil spills; Nonpoint: deforestation

• Point: acid rain; Nonpoint: agricultural runoff

How can a rain barrel help manage water resources?

• It increases the efficiency of how water is used which ultimately reduces the total amount of water a household uses.

• It is a technology that helps purify water to be reused again.

• It is a technology that replaces a household's need for purified water.

• It is a conservation method that can help reduce the amount of purified water a household uses.

Which of the following is a management method that can help conserve water and reduce runoff caused by farming?

• Crop rotation, where farmers plant different crops based on the season to improve the soil health and optimize nutrients in the soil.

• Fertilizing, where farmers add nutrients to the soil to increase crop production and health.

• Overgrazing, where animals are allowed to excessively eat plants which reduce ground cover.

• Tilling, this allows for better absorption, farmers dig up the land after each growing session to remove weeds and roots.

Which statement below describes how acid rain harms Earth?

• Pollution in the atmosphere affects precipitation which can affect living things and water.

• Pollution in the atmosphere can change precipitation to be more beneficial for plants and ecosystems.

• Pollution that enters the atmosphere always stays in the atmosphere.

• Air resources continually need to be replaced because gas particles are lost during precipitation.
