This blue speck in the space holds the past, present, and future of our very existence.

Gravity drew particles together to form pebbles which then formed boulders, and eventually, the earth. As its heart is a solid inner core powered by liquid outer core. Above this sits the mantle, made of following silicate rocks, and Rocky crust. This Rocky mass is the third planet from the sun, orbiting the star from an average distance of about 93 millions miles. It's close enough to the sun to be warm unlike the cold gas giants. But not so close that its surface is exposed to extreme heat and solar radiation as is the case with Mercury. Bharat unique position in the solar system allows it to house phenome...
