Briefly outline the steps in the formation of our solar system, according to the nebular theory
What will be an ideal response?
The nebular hypothesis describes the formation of the solar system from a rotating cloud of space dust and gases (a nebula). Due to gravitational forces, the cloud began collapsing in and dust particles started colliding together to form planetesimals. Planetesimals collided into each other, forming protoplanets, and eventually repeated accretions and collisions grew these protoplanets into the planets of the solar system.
