Earth & Space Science
You will learn what chemistry and science are all about. Then learn about the various ways that chemistry affects the environment, specifically fossil fuels and renewable energy sources.
After completing this tutorial, you will be able to complete the following:
1. Where does most of the world's energy come from?
~ Most of the world's energy comes from fossil fuels, such as coal, lignite, oil, natural gas, and derivatives.
2. How long does it take for fossil fuels to form?
~ It takes millions of years for fossil fuels to form.
3. How do fossil fuels harm the environment?
~ Burning fossil fuels releases dangerous pollutants, such as carbon dioxide and carbon monoxide, into the environment.
4. What are some forms of renewable energy?
~ Some common forms of renewable energy are water, sunlight, wind, and geothermal energy.
5. What is the main problem with renewable energy sources?
~ The main problem with renewable energy sources is that energy obtained from these sources is more expensive to use than the energy obtained from fossil fuels.
