MODULE X COAL AND OIL FORMATION
• In wet environments the forest debris was protected from 02 to become peat. It eventually got buried where it was heated and squeezed onto coal.

Presentation Notes
Oil forms from dead organisms in ancient seas. Over the years, the organisms decayed in the sedimentary layers. In these layers, there was little or no oxygen present. So microorganisms broke the remains into carbon-rich compounds that formed organic layers. The organic material mixed with the sediments, forming fine-grained shale, or source rock. As new sedimentary layers were deposited, they exerted intense pressure and heat on the source rock. The heat and pressure distilled the organic material into crude oil and natural gas. The oil flowed from the source rock and accumulated in thicker, more porous limestone or sandstone, called reservoir rock. Movements in the Earth trapped the oil and natural gas.
