Earth Planet Formation Documentary In Hindi
By Learn With Rishabh.
Earth formed about 4.5 billion years ago from planetesimals in the protoplanetary disk surrounding the young sun. These planetesimals collided and merged to form larger bodies called protoplanets. Over time, the protoplanets continued to collide and merge, eventually forming the Earth. The process of differentiation, where heavier elements sink to the core and lighter elements rise to the surface, caused the Earth to develop distinct layers: a metallic core, a mantle, and a crust.
The solar system began as a cloud of gas and dust called a solar nebula. The nebula began to collapse under its own gravity, spinning faster and faster as it shrank. This caused it to flatten into a disk shape. The center of the disk became the sun, while the rest of the gas and dust flattened into a protoplanetary disk. Over time, the particles in the disk began to stick together to form planetesimals, which then collided and merged to form the planets. The inner planets, including Earth, are rocky and small, while the outer planets are large and made mostly of gas and ice.
