1. How did the earth form?
Answers
Answer:
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Answer:
our Earth is apart of solar system, which was formed from the gas clouds and dust that remained after the sun was formed around 4.6 billion years ago. some of the dust, pieces of Rock and gas that were orbiting the sun smashed against one another, and began to heat up, until the entire mass melted.
as mass grew, it became large enough to develop a magnetic force or gravity. this force kept the material from flying off into space again.
it also attracted more material, until the area around became free of debris and the earth took shape. some material in this mass that were heavier than others, fell towards the center of the mass to become the Earth's core. The rest formed the planet's mantle, crust, and atmosphere. all the planets in the solar system we're formed this manner.
