Earth-like planet forming, illustration. Planets like the earth form by accretion within a nebula, the disc-shaped cloud of gas and dust left over from the formation of a star. Frequent collisions with other bodies generate heat and lead to extreme volcanism. Impacts also cause cratering on the planet's surface, and floods of molten lava. Over time, the planet cools, causing the formation of a solid crust. | |
