Glossary term: Earth's Rotation

Redirected from Polar Axis

Description: Earth does not emit its own visible light and receives its light from the Sun; the amount of this light at any one place on the surface varies according to Earth's position relative to the Sun. Earth has two motions that are moving at the same time: a rotation around it axis, and a rotation around the Sun. The rotation of Earth around its axis results in the phenomena of night and day, as the location of a particular place relative to the Sun changes in a gradual and regular manner over a 24 hour cycle as Earth turns from west to east.
