hypothesis on coal mining

Lesson Plan Fossil Fuels: Chocolate Chip Mining

Mining. Mining is the process of extracting coal, oil, and natural gas from the ground. Strip mining (also known as open cast, mountaintop, or surface mining) involves scraping away earth and rocks to get to coal buried near the surface (Greenpeace, 2010). This often has significant impact on the surrounding land, plants, and animals.
