How the Earth and moon formed, explained. The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.

What happens is when this whole earth was super hot and was kind of in a fluid state, the heavier elements were allowed to sink down, when everything was fluid.In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value. ….
