The Geology of Coal

The Geology of Coal

In this video, a geologist describes how coal, a sedimentary rock, was formed when organic materials piled up in swamps millions of years ago. Over time, heat and pressure transformed the buried materials into forms of coal that cause acid mine drainage when exposed to oxygen. OER Level
