True Moon

The text states that lunar seas on the Moon are frozen lava and their smoothness is due to low gravity.

Infact verdict: True (80/100).

The claims about the lunar seas being frozen lava and their smoothness due to low gravity are supported by scientific evidence. The lunar maria are indeed solidified lava plains formed by ancient volcanic activity, as confirmed by reliable sources like the BBC. The smoothness of these plains is attributed to the Moon's low gravity, which allows lava to spread more evenly, as supported by sources like ScienceDirect and Wikipedia.
