Question

Leah Abbate · Accepted Answer

There aren't 5 theories, there is only 1 theory that is broadly accepted by scientists.

The nebular hypothesis explains how the solar system; our sun, the planets, the Earth and all the moons formed as part of one continuous process. Here are steps:

step 1 the birth of our solar system began as dust and gases (nebula) started to gravitationally collapse

step 2 the nebula contracted into a rotating disk that was heated by the conversion of gravitational energy into thermal energy. .

step 3 cooling of the nebular cloud caused rocky and metallic material to condense into tiny solid particlesAll of the hydrogen collapsed and formed the sun

step 4 repeated collisions caused the dust-sized particles to gradually coalesce into astroid-sized bodies

step 5 within a few million years these bodies acreted into the planets, including the Earth.
