Solar System

The light emitted from the Sun and the distance from the Sun were suitable to produce temperatures on Earth that would be suitable for life. Being too close or too far away from the Sun would prevent liquid water being present. The time taken for the Earth to rotate on its axis produced a day/night cycle that was fast enough to minimise excessive heating or cooling.

Axis of Rotation

The axis of rotation is at an angle to orbit around the Sun which produce seasonal variations conditions as the Earth orbits the Sun

Speed of Rotation

The temperature of the Earth's surface rises when it is exposed to sunlight and falls when tis not. The 24-hour period of rotation of Earth around its axis reduces temperature extremes

Magnetic Field

The molten layers beneath the crust produce the Earth's magnetic field that deflects the Solar wind and prevents biologically damaging radiation reaching the Earth's surface.
