The Moon Mr. Hemmert Fourth Grade Robertsdale Elementary
The Moon The moon is Earth's only natural satellite. The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (regolith). The moon has no atmosphere.

The moon has no atmosphere.Earth's The moon revolves around the Earth in about one month (27 days 8 hours). It rotates around its own axis in the same amount of time. The same side of the moon always faces the Earth; it is in a synchronous rotation with the Earth. The moon revolves around the Earth in about one month (27 days 8 hours). It rotates around its own axis in the same amount of time. The same side of the moon always faces the Earth; it is in a synchronous rotation with the Earth.
Craters The surface of the moon is scarred by millions of (mostly circular) impact craters, caused by asteroids, comets, and meteorites. There is no atmosphere on the moon to help protect it from bombardment from potential impactors (most objects from space burn up in our atmosphere). Also, there is no erosion (wind or precipitation) and little geologic activity to wear away these craters, so they remain unchanged until another new impact changes it.

Phases of the Moon The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7 hours 43 minutes.

Moon Phases As the moon circles the Earth, the shape of the moon appears to change; this is because different amounts of the illuminated part of the moon are facing us. The shape varies from a full moon (when the Earth is between the sun and the moon) to a new moon (when the moon is between the sun and the Earth).

Full Moon A full moon appears as an entire circle in the sky. A full moon appears as an entire circle in the sky.
GIBBOUS MOON A gibbous moon is between a full moon and a half moon, or between a half moon and a full moon. One appropriate definition of "gibbous" is "swollen on one side." A gibbous moon is between a full moon and a half moon, or between a half moon and a full moon. One appropriate definition of "gibbous" is "swollen on one side."
Quarter Moon/Half Moon A half moon looks like half a circle. It is sometimes called a quarter moon. A half moon looks like half a circle. It is sometimes called a quarter moon.
Crescent Moon A crescent moon is part way between a half moon and a new moon, or between a new moon and a half moon. A crescent moon is part way between a half moon and a new moon, or between a new moon and a half moon.
New Moon The new moon is the phase of the moon when the moon is not visible from Earth, because the side of the moon that is facing us is not being lit by the sun. The new moon is the phase of the moon when the moon is not visible from Earth, because the side of the moon that is facing us is not being lit by the sun.
