Geology Processes and Concepts

Mr. Leed introduces geology, emphasizing its importance in understanding Earth's resources, history, and predicting natural events. He explains the Earth's structure, differentiates rocks from minerals, and describes geological processes like the rock cycle, weathering, and erosion. The video also covers sedimentary rock formation and the roles of melting and crystallization in geology.
