Earth Science : Types of Rock

The video explores the Geology Learning Center, focusing on the three types of rocks: sedimentary, igneous, and metamorphic. It explains how sedimentary rocks form from layers of sediment, often containing fossils that provide clues about past environments. Fossil fuels like coal and oil originate from these rocks. Igneous rocks form from cooled magma or lava, with volcanic rocks like basalt being common. Metamorphic rocks result from existing rocks undergoing heat and pressure, altering their structure. The video concludes with a musical recap of the rock types.
