Geography

Star formation, formation of planets, and our solar system

In this Class 11 Geography topic from “The Origin and Evolution of the Earth,” students explore how stars form from vast clouds of gas and dust and how planets emerge from the material surrounding a young star. They examine the formation and organisation of the solar system, including the Sun, planets, satellites, asteroids and comets, while connecting these processes with Earth’s place, structure and early development within the wider universe.
