We know from the Apollo missions and unmanned probes that the moon's surface is covered with loose, unconsolidated material with a texture similar to soil on earth.  How did this material form on the moon?
A) The same as Earth, but soils are ancient from a time when the moon still had an atmosphere and water.
B) The material is produced by spalling from rock surfaces caused by the extreme heat-cold cycles as the moon rotates through a 1 lunar day, or approximately one Earth month.
C) The loose material is mostly micrometeorite fragments and ejecta from impact craters, so is very different from soil on Earth.
D) The material is mostly volcanic ash ejected from volcanos that are no longer active.
