WebFeb 20, 2024 · As Earth spins on its axis it wobbles slightly, similar to when a spinning top slows down. This wobble is called precession, and has an affect on seasonal extremes. (Image credit: NASA) In rotational axis Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the … See more Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space.

WebJan 16, 2024 · If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. At first, only small regions of terra firma around the equator would rise out of the retreating waters. Eventually, there would be a huge mega-continent wrapped continuously around the Earth at the equator. WebJun 12, 2024 · You added energy to it by starting the spin off with your hand. Eventually it stops because the ground it is spinning on is taking energy away from the toy top through something called friction.
