Answer 1

When solar nebula collapsed to form our sun, a disk of material formed around the new star. The temperature around the protoplanetary disk was not uniform. Since different materials condensed at different temperatures, our solar system formed different types of planets. this dividing line in our solar system is called frost line.

Hydrogen compounds such as water and methane, typically condensed at low temperatures and remain gaseous inside the frost line. The heavier rocky and metallic materials are condensed at high temperature thus inner planets are made almost rocky.

(The frost line marked an important deviding point in the solar nebula.Within the frost line,temperatures were too high for hydrogen ices to form.The only solid particles made of metal and rock.Beyond the frost line , where the hydrogen compound could condense , the solid particles included ices as well as metal and rock.
