Human Impact on Environment

Which of the following is a way by which cars can pollute the environment?

• New cars release a lot of pollution into the air

• Tires evaporate and release gas into the atmosphere

• Older cars release carbon monoxide into the atmosphere

• the heat generated by car engines contributes to global warming

Which of the following statements is true?

• Natural resources are infinite because they are renewable

• the water cycle and gravity keep all the fresh water on the planet the same

• Human need for resources can't overcome what is available

• Non renewable resources are only rare resources less than 1% of the total matter on the planet

How can ground pollutants affect the local fresh water supply?

• The chemicals evaporate underground and come back in the rain water, filling lakes and rivers with toxic chemicals.

• Erosion of soil causes those chemicals to leak into the ground water supply and end up in lakes and rivers

• The chemicals absorb down their concentration gradient and eventually move to lakes and rivers

• When plants are harvested the soil and excess plant parts are dumped into the water supply

When certain chemicals such as CFC (chlorofluorocarbons) react with Ozone (O3), ozone breaks down to O2 (oxygen gas). Why would this have a negative impact on the climate?

• More oxygen causes more storms

• More oxygen in the atmosphere increases plant growth

• Ozone is part of what protects us from harmful UV radiation.

• More oxygen leads to increased human overpopulation and desertification

Which of the following is most likely to cause desertification?

• Cows digesting plants and releasing methane to break down ozone

• Lack of vegetation causing increased soil erosion, which displaces water from a region

• greater human population in a region causing flooding

• More traffic in a soil rich region would kick up dust clouds which cause lightning storms
