What is black spot in Moon?
Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they’re actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth.
Why do lunar maria appear darker?
The maria appear dark due to their high iron and titanium content that lead to about half of the highlands albedo. Lunar basalts are less porous than the anorthosites, so highland’s craters are generally deeper than maria’s ones. However, craters may be degraded by the cumulative effects of small impacts.
