Dating lunar rocks

The Moon: The surface of the Moon is covered with a fine powdery material that scientists refer to it as “lunar regolith”.Nearly the entire lunar surface is covered with regolith, and bedrock is only visible on the walls of very steep craters.However, landings performed by robotic Surveyor spacecraft showed that the lunar soil was firm enough to support a spacecraft, and astronauts later explained that the surface of the Moon felt very firm beneath their feet.During the Apollo landings, the astronauts often found it necessary to use a hammer to drive a core sampling tool into it.Due to a combination of erosion, alluvial deposits (i.e.moving water deposing sand), volcanic eruptions, or tectonic activity, the material is slowly ground down and laid out over solid bedrock.

The reason for this is because lunar regolith is sharp and jagged.When you’re walking around on soft ground, do you notice how your feet leave impressions?Perhaps you’ve tracked some of the looser earth in your yard into the house on occasion?The word is derived from the combination of two Greek words – rhegos (which means “blanket”) and lithos (which means “rock).Earth: On Earth, regolith takes the form of dirt, soil, sand, and other components that are formed as a result of natural weathering and biological processes.
