Which characteristic of our solar system is most crucial to support life on Earth?

• the length of time of Earth’s revolution

• distance between the Earth and Sun

• the distance between the Sun and other stars

• the composition of Earth’s Moon

The Earth moves in predictable patterns. One of these patterns causes approximately 12 hours of daylight and 12 hours of darkness during a 24-hour period in areas around the equator. This movement is referred to as —

• a rotation

• an equinox
