what are the light areas on the moon called
Moon The lighter-coloured regions of the Moon are called terrae, or more commonly highlands, because they are higher than most maria. They have been radiometrically dated to having formed 4.4Â billion years ago, and may represent plagioclase cumulates of the lunar magma ocean.[61][62] In contrast to Earth, no major lunar mountains are believed to have formed as a result of tectonic events.[72]
