    The Moon really doesn't have either an atmosphere or soil. It is too small and too hot on the day side to hold on to gases. So, no significant atmosphere.

    Soil is a mixture of pulverized rock (regolith) and organic material with variable amount of air and water filling the pore spaces. The Moon does not have air, liquid water, or organic material. So, its surface is entirely covered by regolith. The material that makes up the regolith ranges in size from huge boulders to very fine powder. The larger fragments are created by the impact of larger meteors that strike the Moon. The finer material is created by the impact of microscopic meteors.

    1.) (atmosphere)
    The atmosphere of the Moon is very tenuous and insignificant in comparison with that of the Earth. One source of the lunar atmosphere is outgassing: the release of gases such as radon that originate from radioactive decay within the crust and mantle. Another important source is the bombardment of the lunar surface by micrometeorites, the solar wind, and sunlight, in a process known as sputtering. Gases that are released by sputtering can either:

    * be reimplanted into the regolith as a result of the Moon's gravity;
    * be lost to space either by solar radiation pressure or, if the gases are ionized, by being swept away in the solar wind's magnetic field.

    The elements sodium (Na) and potassium (K) have been detected using Earth-based spectroscopic methods, whereas the element radon-222 and polonium-210 have been inferred from data obtained by the Lunar Prospector alpha particle spectrometer. Argon-40, helium-4, oxygen and/or methane (CH4), nitrogen gas (N2) and/or carbon monoxide (CO), and carbon dioxide (CO2) were detected by in-suit detectors placed by the Apollo astronauts.

    The average daytime abundances of the elements known to be present in the lunar atmosphere, in atoms per cubic centimeter, are as follows: H <17, He 2-40x103, Na 70,K 17, Ar 4x104, yielding ~8x104 total atoms per cubic centimeter, marginally higher than the quantity posited to exist in the atmosphere of Mercury.. It is worth noting however, that while this greatly exceeds the density of the solar wind (a component of the lunar atmosphere), which is usually on the order of just a few protons per cubic centimeter, the lunar atmosphere is less than one trillionth the density of the Earth's atmosphere at sea level. The Moon is usually considered to not have an atmosphere, as it cannot absorb measurable quantities of radiation, does not appear layered or self-circulating, and requires constant replenishment given the high rate at which the atmosphere is lost to space (solar wind and outgasing are not primary components of the Earth's, or any stable atmosphere yet known).

    The Moon may also have a tenuous "atmosphere" of electrostatically-levitated dust. See moon dust for more details.
     
    2.) (lunar soil)
    Lunar soil is the fine regolith found on the surface of the Moon. Its properties can differ significantly from those of terrestrial soil. It is essentially devoid of moisture and air, two important components found in soil on Earth.

    The term lunar soil is often used interchangeably with "lunar regolith" but typically refers to the finer fraction of regolith, that which is composed of grains one centimeter in diameter or less. Some have argued that the term "soil" is not correct in reference to the Moon because soil is defined as having organic content, whereas the Moon has none. However, standard usage among lunar scientists is to ignore that distinction. Lunar dust generally connotes even finer materials than lunar soil, the fraction which is less than 30 micrometres in diameter.
     
    3.) (craters)
    The smallest craters found have been microscopic in size, found in rocks returned to Earth from the Moon. The largest crater called such is about 360 kilometers (200 miles) in diameter, located near the lunar South Pole. However, it is believed that many of the lunar maria were formed by giant impacts, with the resulting depression filled by upwelling lava.

    Craters typically will have some or all of the following features:

    * a surrounding area with materials splashed out of the ground when the crater was formed; this is typically lighter in shade than older materials due to exposure to solar radiation for a lesser time
    * raised rim, consisting of materials ejected but landing very close by
    * crater wall, the downward-sloping portion of the crater
    * crater floor, a more or less smooth, flat area, which as it ages accumulates small craters of its own
    * central peak, found only in some craters with a diameter exceeding 16 miles (26 km); this is generally a splash effect caused by the kinetic energy of the impacting object being turned to heat and melting some lunar material.

    thanks for a great question!
