How the Earth Was Made- The Birth of the Earth

Learn How the Earth Was Made

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.

In this video, you will take a trip four billion years back in time to show the formation of planet Earth; how molten material came together and solidified into rock; how the world survived a collision with a Mars-sized planet; how water arrived and formed the oceans, and when the first lifeforms appeared.
