Gravity. If you jumpin the air you don't fly.
earth does in a day is that it spins around around the sun
no the earth spins on it's axis while rotating around the sun
My rough guess is that "faster (inner) core is relic of tidal deceleration." Since tidal deceleration of the Earth is due to frictional force exerted by ocean tide on the ocean bottom surface, core can decouple in the tidal braking. (sunghona@kasi.re.kr)
There is no "purpose"; the density of the materials in the outer core are less pressured and spin slower than the inner core. NOTE: the inner core spins faster than the outer, creating Earth's magnetic field.
Moon also revolve. Earth revolve round the sun and moon revolve round the earth.
1.Earth has Strong Gravity. 2.Earth doesn't spins so fast!
The Earth's rotation
it spins and aprox. 100km every DAY
It depends on what latitude you are at but the equatorial rotational speed is 1,670.5 km/hr
15 hours
It spins at the same rate wherever you are Maybe equator
The illuminated patch on the earth's surface drifts westward relative to a fixed point on the earth as the earth spins eastward.
The Earth spins at approximately 1,000 miles per hour at the equator. However, this speed decreases as you move towards the poles.
the earth spins on an axis, which is carried over by conservation of angular momentum when the earth was created
The earth spins a little over 1,000 mph near the equator. The earth spins about 0 mph near the north & south pole.
The Coriolis effect is caused by the rotation of the Earth. As the Earth spins on its axis, objects that move across its surface are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection is due to the difference in speed of rotation at different latitudes.
That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up
