SCSA Virtual Globe

Planet Earth spins around an imaginary axis of rotation once every 24 hours (shown center panel, below); the word used to describe Earth's daily motion depends upon your viewpoint. Viewed from above the North Pole, the Earth appears to rotate counterclockwise (shown left panel, below); viewed from above the South Pole, the Earth appears to rotate clockwise (shown right panel, below). Observe that most of the world's landmasses are located in the Northern Hemisphere (contrast the left & right panels, below), therefore most people learn that the Earth rotates counterclockwise.
