It has very few, it's surface is dominated by water ice.
A magnetic pulse is released and the force pushes the magnetic feild of the Earth. Oh and by the way I am 11 years old makes you feel stupid doesn't it!
The moon is less massive and smaller than Earth, so the force of gravity on objects near the moon's surface is less than on Earth. The gravity of the moon is around 1/6 the gravity of the Earth. The acceleration of gravity on the moon is 1.6 meters per second per second.
The earth has gravity that pulls things to itself. The earth pulls human beings, the air we breathe, water, animals, trees, etc., to itself by its gravity.
