"Moon Seas" is another term for "Moon Marias".
Marias (singular: Mare) were formed by ancient volcanic eruptions on the Moon.
They were called "Marias", which is Latin for "Sea", by early astronomers who mistook them for actual seas and oceans.
Maria's can be seen from the Earth because they look dark to the naked eye, due to their high iron-rich compositions.
There are exactly 23 sea's on the moon.
They are:
- Mare Anguis (Serpent Sea)
- Mare Australe (Southern Sea)
- Mare Cognitum (Sea That Has Become Known)
- Mare Crisium (Sea Of Crisis)
- Mare Fecunditatis (Sea Of Fecundity)
- Mare Frigoris (Sea Of Cold)
- Mare Humboldtianum (Alexander Von Humboldt Sea)
- Mare Humorum (Sea Of Moisture)
- Mare Imbrium (Sea Of Showers)
- Mare Ingenii (Sea Of Cleverness)
- Mare Insularum (Sea Of Islands)
- Mare Marginis (Sea Of The Edge)
- Mare Moscoviense (Sea Of Muscovy)
- Mare Nectaris (Sea Of Nectar)
- Mare Nubium (Sea Of Clouds)
- Mare Orientale (Eastern Sea)
