3. Fossil fuels formed when dead plants and animals were buried and crushed
under sediments, and then high heat and pressured turned the material into fossil
fuels.
Homework
4. Answers will vary
5. True
Environmental Impacts
Classwork
1. False
2. Create air pollution
Emit greenhouse gases
Produce hazardous waste
Emit metals
Contribute to acid rain
Can be deadly or catastrophic
Use large amounts of water
Homework
3. Energy production requires water and water requires energy to be treated and
transported. They are interdependent.
4. It is difficult to choose one best energy solution because every energy source
has positives and negatives. There are also many different impacts that an
energy source can have, which may be related directly to the source or to the
collection or conversion of the energy source into useable energy for humans.
