Worksheet: Human Impact on Earth's Systems: Acid Rain
In this worksheet, we will practice recognizing the impact human activity has in causing acid rain and identifying the ways that acid rain damages Earth’s systems.
The chart shows critical pH levels for aquatic organisms. Which two organisms are most at risk from acid rain?
- APerch and frogs
- BCrayfish and mayfly
- CTrout and salamanders
Humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. Power plants release sulfur dioxide and nitrogen oxide when they burn fossil fuels, such as coal, to produce electricity. These pollutants cause acid rain. What name is given to this type of pollution?
- ANoise pollution
- BAir pollution
- CRadioactive pollution
The pie chart shows the main causes of acid rain in the USA. Which of the following would be the best way to reduce acid rain?
- AFinding ways to produce electricity that are less harmful to the environment.
- BReducing harmful emissions from cars by using public transportation.
- CIssuing fines to factories that produce large amounts of pollution.
