Answer 1

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.

Answer 2

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.
