The solar system of which the planet Earth is a part, originally formed out of a large cloud of interstellar gas. The cloud had its own spin, and that angular momentum was given to the various objects which condensed out of it.
If you wish to trace this back even further, and ask why the original cloud was spinning, we can go back to the Big Bang, an explosion which formed the universe as we know it. The original momentum of the Big Bang was entirely linear; everything moved away from the center of the explosion. However, linear motion is easily warped into angular motion, by gravitational interaction.
Do you mean what Law of Conservation keeps the Earth spinning at the same rate? If so, that's the Conservation of Angular Momentum.
Because earth is so big that we can't feel it spinning unless you are at the middle of the core.
It is conservation of [angular] momentum.
Very little as it is spinning at a constant speed. However, the moon does affect the Earth's seas, greatly.
The spinning of the Earth affects the Earth's water by creating currents and winds. The spinning of the earth is necessary to complete the water cycle and establish weather patterns.
Shoot the duck is a move in figure skating were the skater begins spinning and squats down and keeps spinning while extending the leg... keeps spinning for a couple seconds then tucks in leg and pushes up gracefully while still spinning.
Bodies spin through momentum; nothing's stopping them from spinning so they keep on spinning. The moon have a complication, because it's orbiting the Earth they have become tidally locked; so the Moon's rotation period is that same as the time to orbit the Earth.
We don't. gravity is slightly more on a non-spinning earth.
RotationThe spinning of the Earth on its axis is known as 'the Earths rotation'Rotation.Rotating.rotation (as opposed to orbiting, which describes the earth's movements around the sun)
No, the Earth is not spinning backwards. It rotates on its axis in a consistent direction, which causes day and night.
Yes, the Earth's core is spinning within the planet's interior.
No, the Earth will not stop spinning. The Earth's rotation is a fundamental part of its natural processes and is expected to continue indefinitely.
