W/o an atmosphere to erode them, they stay fresh.
because scientists now know the age of the moon, they can count the number of impacts craters to find the rate of the cratering science the birth of our solar system. by knowing the rate of crating, scientists are able to use the number of the craters on any body of water to estimate how old the body of water is. this is easier because sceintsts don't need to bring back the rock to find out.

Why does the moon have larger craters than the earth?
The Moon has no atmosphere to protect it. A meteorite that would have burned up on entry on its way to Earth would hit the moon. Also, without atmosphere there's no erosion to fill the crates in and smooth them out. Without any water, more of the Surface is visible.
How does the absence of an atmosphere affect the Moon's surface temperature?
Well, atmospheres help absorb heat, so it traps in heat from the sun to make it warmer, so the absence of an atmosphere on the moon affects it by making it cooler because without an atmosphere, there is no way to trap in and keep heat.
Why do we need the atmosphere?
You wouldn't be here / alive without atmosphere.
Why are there craters in the moon?
There are two reasons why the Moon (like other moons, and Mercury) has so many craters, and both are related to its lack of an atmosphere. 1) There is no atmosphere to prevent small-to-medium meteors from striking the surface. On Earth, only the largest and densest meteors can make it to the surface without vaporizing or exploding. 2) There is no volcanic activity, or oceans, or winds on the Moon. On Earth, scars from impacts would be lost due to continental drift, volcanic activity, or simple weathering by water, air, and plants. So what you see on the Moon are some of the BILLIONS of collisions with it over BILLIONS of years. Only a few are weathered by solar activity on the rocks, and a much larger number erased by later impacts at the same locations.
How does the atmosphere interact with the other spheres?
The atmosphere is one of the most important spheres. If there was no atmosphere there would be no biosphere. If there was no biosphere there would only be the geosphere. Also, without no atmosphere there would be no more hydrosphere because of space radiation. So without the atmosphere there would only be the geosphere.

What happens if there was no atmosphere?
We would all die because without it we would have no air to breathe.
Why is Earth's atmosphere mainly heated from the ground up?
Solar radiation mostly passes through the atmosphere without heating it, due to its wavelength. It does not pass through the ground, however, and it heats the ground. The ground emits radiation at a wavelength dependent on its temperature. This radiation happens to be in the thermal infrared part of the spectrum, or in other words, sensible heat. Therefore, the atmosphere is heated by the surface, whereupon the heat tends to rise and heat the lower atmosphere.
Why their is no air in space?
The atmosphere we breath is held round the earth's surface due to earth's gravity. Without this gravity, earth's atmosphere would disperse into space. Because our moon's gravity is weak, so there is no atmosphere on the moon.
Why do all planets with and without atmospheres collide with meteoroids?
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.
What the most ultraviolet radiation is blocked from reaching earths surface by what substance found in the atmosphere?
Ozone in the atmosphere blocks most of the UV radiation from the Sun... Without it's protection - the planet would overheat.
How can an atmosphere affect the temperature of the planet surface?
The atmosphere moderates temperature changes, keeping the surface warm at night and cool in the day. Without an atmosphere on Earth the temperature would probably go from about +100 degrees to -100 degrees every 24 hours. The atmosphere keeps it nicely within a range of ten degrees usually. Carbon dioxide allows radiant heat through to the Earth's surface but blocks heat being radiated away from the surface which is at a relatively low temperature. So it produces a 'greenhouse' effect which raises the surface temperature, but only by a little at present. On Venus, which has a 95% carbon dioxide atmosphere, the greenhouse effect has made the surface temperature 400-500 degrees C.
Why do meteors burn up entering earth but not the moon?
The reason meteors burn up is due to friction in the Earth's atmosphere. An object moving very quickly through the atmosphere heats up due to friction with the atmosphere and this heat causes it's surface to boil and evaporate and sometimes to explode. The moon has no appreciable atmosphere and so objects would just plummet to its surface without resistance.
What is the life-supporting region of earth?
All life on Earth happens in the Troposphere, the lowest level of the atmosphere below about 25,000 feet. Above that altitude, in the stratosphere, it is difficult for life to exist without assistance.
How would earth be different without the atmosphere here?
Without an atmosphere, Earth would be a barren and inhospitable place. The atmosphere provides several vital functions such as filtering harmful solar radiation, regulating temperature, and providing the necessary gases for plants and animals to survive. Additionally, the absence of an atmosphere would mean no air pressure, making it impossible for liquid water to exist on the surface.
Is planet Mercury smooth?
Without an atmosphere to protect it from meteor impacts, the planet Mercury is heavily cratered. This includes the basin Caloris, which is a 1500-km wide impact crater with associated lava flows and crustal splitting.
What are some results of the Moon's thin atmosphere?
Our moons lack of atmosphere means that it is a vacuum at the surface, it's like being in space. The lack of atmosphere means that meteors are able to hit the moon without being burnt up by frictional forces. The lack of atmosphere also means that there is no weather, wind or rain.
