Some lunar craters are cut by rills, which are cracks in the surface. Rills may be faults, possibly caused by ancient tectonic activity or cooling processes.

Weathering is indeed done on the moon by the intense Solar Radiation that bombards the lunar surface daily. Temperatures on the Lunar surface vary widely on location. Although beyond the first few centimeters of the regolith the temperature is a nearly constant -35 C (at a depth of 1 meter), the surface is influenced widely by the day-night cycle. The average temperature on the surface is about 40-45 C lower than it is just below the surface.

In the day, the temperature of the Moon averages 107 C, although it rises as high as 123 C. The night cools the surface to an average of -153 C, or -233 C in the permanently shaded south polar basin. A typical non-polar minimum temperature is -181 C (at the Apollo 15 site).

The Lunar temperature increases about 280 C from just before dawn to Lunar noon. Average temperature also changes about 6 C betwen aphelion and perihelion. Meaning the closest and furthest the moon comes to; and far away it gets from the sun.

Lunar Regolith and Fragmental Breccias

Regolith is the name given to the layer of unconsolidated material at the surface of a planet – the loose stuff that overlies the solid rock. On Earth, soil is part of the regolith, and lunar regolith is consequently often called “soil.”

Answer 2

Hi. Have you looked at the Moon? You should try it with binoculars. The rays are caused by material that was blasted onto the Moon's surface by impact with a large asteroid or comet. The Moon has no atmosphere so 'weathering' is done only by meteorites and possibly mechanical heat/cold based expansion and contraction. The 'soil' is called regolith, I think, and it's the result of small particles also generated by impact. Now grab some binoculars and take a look!

Answer 3

I dont understand what you are asking. You should make it a little more clear so people can give you accurate responses :o)

Answer 4

rays are ejecta from meteor impacts.
