ANSWER: c) Because the moon has no atmosphere, it is not possible for geologic events to occur on the moon.
Atmosphere is responsible for some of the geological changes (like in Earth) since this is an essential part to allow winds and erosion due to water to form. Only with an atmosphere could a surface change, and the moon, sadly, has none of it. Thus, the surface of the moon will always be the same or has changed very little (when rare asteroids or space debris bump into it ie).
