Question

how earth formed?????​

Answer 1

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

Explanation:

Step 1: accretion of cm sized particles.

Step 2: Physical Collision on km scale.

Step 3: Gravitational accretion on 10-100 km scale.

Step 4: Molten protoplanet from the heat of accretion.

Final step is differentiation of the earth: Light objects float; heavy objects sink.
