Question
Explain the origin of the earth and the solar system according to the Nebular cloud theory.
Answer
- There existed a big cloud of hot gases and dust
- This cloud which was rotating at a very high speed flattened into a disk due to centrifugal force.
- Very hot materials concentrated at the centre of the rotating cloud and led to the formation of the sun
- Some masses of gases and dust were thrown off as the cloud continued to rotate
- The particles consolidated, cooled and contracted to form planets
