Gravity.
When the earth started to coagulate from a loose pile of asteroids, it gained little rotation. But it gained most of its rotational energy when a planet the size of mars hit it (Also forming the moon.) Other planets gain their spins from billlions of years of spinning around the sun (in theory)
First, a big flying rock came and just hit the earth before life ever started and it is still spinning.
It would effect the earth's electromagnetic field as it is the spinning of the earth's core that creates the field.
Because earth is so big that we can't feel it spinning unless you are at the middle of the core.
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.
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)
I thew it sunday, now somewhere over mogolia
The Earth won't, actually can't stop spinning in a human timescale.
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.
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.
