Earth is the only planets that support life. Envision a line passing through the center of Earth that goes through both the North pole & the South Pole, this imaginary line is called an axis. Earth spins around its axis, just as a top spins around its spindle. Rotation & Revolution are two motions of the earth. When the earth spins around its axis, that movement of spinning is called rotation of Earth and when earth revolves around the sun, that movement is called the revolution of Earth.
