Question

पृथ्वी की उत्पत्ति कैसे हुई ?

Answer 1

I am giving answer in English.
While no one knows for certain how the Earth formed, scientists theorize that it formed over 4 million years ago after the Sun went through its initial formation, gravity began to draw heavy particles together into a planet and solar winds blew away lighter gases. These heavy particles become the core of the Planet. As the mass continued to grow, heavier particles sank to the center.
