Earth composition and Rock cycle

Explore the fascinating history of Earth’s composition and the rock cycle throughout geological eras. From the formation of the Earth 4.6 billion years ago to the emergence of human civilization merely 5,000 years ago, this overview delves into the Precambrian, Paleozoic, Mesozoic, and Cenozoic periods. Learn about the different types of rocks—igneous, sedimentary, and metamorphic—as we examine key concepts like the rock cycle, plutons, and batholiths. Understand how Earth's crust and its composition have evolved over time, shaping the planet we inhabit today.
