According to the giant impact theory, a giant Mars-sized object collided with Earth. This collision likely resulted in the spinning of Earth which creates length of a day on Earth.
Answer;
Spinning of earth
Length of a day
According to the giant impact theory, a giant Mars-sized object collided with Earth. This collision likely resulted in the spinning of Earth which creates length of a day on Earth.
Explanation;
- The giant impact theory suggests that the moon formed from the debris left over from a collision between the Earth and a giant Mars sized object, about 4.5 billion years ago.
- Therefore, the collision between a proto-planetary Earth and a Mars-sized proto-planet called Theia, resulted to debris that later cooled and coalesced to form the moon.
- Further according to the theory, more than 60 percent of the moon should be made of chemical material derived from Theia.
