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.
