The answer is that the Earth has more meteoroids hitting it, but most do not survive to impact the surface. The Earth has a protective atmosphere that burns up a lot of meteors. Most others are slowed enough that they don't make a big crater.
The ones that do make it to the surface may fall into water, which covers 3/4 of the planet, and these craters are hard to locate. For land impacts, the actions of the atmosphere (rain, winds etc) erode the impact craters, as does geologic and volcanic action. So what we see are only a tiny number of persistent craters that have avoided obliteration.
The Moon does not have any of these forces at work, so almost all of the impacts since the moon was formed can be seen on its surface. The major changes in the craters are made by later impacts at the same locations.
Astronauts weigh less on the Moon than on Earth because the Moon has less mass and gravity than Earth. The gravitational force on the Moon is about 1/6th that of Earth, so objects (including astronauts) weigh less on the Moon due to this weaker gravity.
The moon has weaker gravity than Earth does.
because the moon has less mass then earth
There is gravity on the moon. It is about on sixth what it is on Earth. This is because the moon has less mass than Earth does.
The gravity is less on the Moon, because the Moon is smaller than earth; it has less mass, and therefore "sucks" less than the earth. Weight is gravity times mass, you have the same mass on Earth and on the Moon (and in space), but weigh less on the moon.
The gravitational force on the Moon is less than that on Earth because the Moon has less mass than Earth. Gravity is directly proportional to mass, so the smaller mass of the Moon results in a weaker gravitational force.
Since the Moon's gravity is 1/6 that of Earth, the Moon's gravity is 5/6 less than that of Earth.
It doesn't. The moon has less gravity than Earth because it has less mass.
Gravity is weaker on the moon than on Earth, meaning objects weigh less there.
The Moon has much less mass than the Earth.
The moon is smaller than earth. The moon is on fourth of Earth, and has less gravity. You would weigh about one sixth on the moon than on the Earth.
Men weigh less on the moon because the moon's gravitational pull is weaker than Earth's. The gravitational force depends on the mass of the celestial body, so with the moon being smaller than Earth, there is less gravitational force pulling objects towards its surface.
