Evolution of the earth

In this Class 11 Geography topic from “The Origin and Evolution of the Earth,” students trace how Earth formed and changed over geological time. They learn about the early solar nebula, the separation of materials within the young planet, the development of the crust, atmosphere and oceans, and the gradual emergence of life. The topic connects major stages of Earth’s evolution with the geological processes that shaped its present structure.
