With No Moon
The moon is very important to Earth. It helps us see at night during a full moon. It pulls Earth's waters to make tides. It even blocks out the sun during a solar eclipse. Without it, life would be very different.
The Moon's Phases
The moon has several different phases that we view from Earth. These phases are caused by us on Earth seeing the moon from different angles. The moon is always halfway in sunlight, but because of the way both the moon and Earth rotate, we always see the same side of the moon. There are 8 phases in total: new moon, waxing crescent, waning crescent, waxing gibbous, waning gibbous, first quarter, third quarter, and full moon. All of these phases occur about once every 29.5 days. The full moon, when we see the entire sunlit side, reflects a lot of light on Earth which helps us see at night, unlike a new moon when none of the sunlit side is visible; it is very hard to see at night during a new moon.
