Question

Quizplus · Accepted Answer

Mascons, or mass concentrations, are believed to be areas of the Moon's maria that have higher than average gravitational pull due to large amounts of solidified magma beneath the surface. These regions were formed from ancient volcanic activity that filled large impact basins with basaltic lava, increasing the density and gravitational pull of those areas.
