| Question | Answer |
|---|---|
| What is point-source pollution? | is pollution that can be traced to one specific source. |
| What is pollutuion? | is waste that is leftovers of things, and most of the time it is caused by humans. |
| What is conservation? | is the careful use of resources. |
| What is nuclear energy? | is energy that comes from nuclear fission. The process to get this energy is dangerous because if the plant leaked, it could destroy everything in its path other long streches of land. |
| What is hydroelectric power? | is energy that comes from the waters forward movement that drives turbines. This type f way to produce power needs to have a dam built in order for it to work. |
| What is solar energy? | is energy that comes from harnessing the sun's heat. People do this by using solar panels. This way to produce energy is very accesable if you live in a place where the sun shines a lot. |
| What is the Safe Drinking Water Act? | is an act that makes sure our wateer is clean by setting a level of pollutants that are allowed to be in our water and if the water goes past that level, then companies can not sell it to you. |
| What is nonpoint source pollution? | is pollution that cannot be traced to one specific source/area. |
| What is wind energy? | is energy harnessed from the wind.We use wind turbines to capture them and the wind is free but can only be "gotton" from windy areas. |
| What is geothermal energy? | is energy taken from underground steam and hot water. The hot water can be directly used to make electricity. This however, can only last so long until you need to drill another hole into the ground for the hot water and steam. |
| What is tidal power? | is the use of the water's back-and-forth motion to create energy.They do this by building a dam over a bay or something like that and the water will drive wind turbines. |
| What is runoff? | is pollution that gets brought into the water when it rains. The runoff is kind of like a snowball rolling down a hill, picking up everything in its way. |
| What is the ozone layer and what does it do? | it traps 95% of the sun's UV rays. |
| What is gobal warming? | is the increase of carbon dioxide in our air. This changes the earth's environment. |
| What is the Clean Water Act and what did it do? | reduces/eliminates point source pollution that gets into water. This led to several sewage treatment plants that stop raw sewage getting into water. |
| What is the Clean Air Act and what did it do? | is the most important air pollution law that the country has. It monitars six pollutants in the air and if they go past the maximum level, then people are advised not to go outside. |
| What are renewble resources? | are resources that replenish over time. |
| What are nonrenewable resources? | are resources that take so long to replenish that they are considered to be nonrenewable. |
| What are fossil fuels? | are hydrocarbons that can be used as a source of energy. They include coal, oil, and natural gas. |
| What are tar sands and oil shale? | are a combination of sand, water, clay, and some balck thick tar. They could replace petroleum. is a rock that has some mixtures of hydrocarbons called kerogen. They too can replace petroleum oil. |
