The primary significance of the spinning Earth are day and night cycles, and allowing for all the planet to have light exposure. By allowing for day and night life can flourish, which is critical for plants that need light. Without the Earth's spin on its axis, half the Earth would be like the moon - in perpetual darkness. It also must be noted that the Earth's spin does not relate to the existence of its magnetic 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)
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.
No, the Earth will not stop spinning. The rotation of the Earth is a natural and constant process that has been happening for billions of years and is expected to continue.
No. And even if we could, the spinning of the rest of the Earth will quickly make the core spin again.
It creates mass.
