"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)
- Oceanus Procellarum (Ocean Of Storms)
- Mare Serenitatis (Sea Of Serenity)
- Mare Smythii (Smyth's Sea)
- Mare Spumans (Foaming Sea)
- Mare Tranquillitatits (Sea Of Tranquillity)
- Mare Undarum (Sea Of Waves)
- Mare Vaporum (Sea Of Vapors)

The "gibbous moon" is too vague a phrase to specify exactly how many of those would be in the lighted portion.
A waxing gibbous moon is when it is more than half full and getting bigger. A waning gibbous moon is when it is more than half full and getting smaller.
The shade of the earth on the moon is what causes the gibbous moon.
Usually its waxing gibbous or waning gibbous, and both are phases of the moon
It's called a waning gibbous moon.
A gibbous moon is a phase of the moon where the illuminated half is greater than the dark half but it is not full. The opposite of a gibbous moon is known as a crescent moon.
In a gibbous moon phase, most of the moon that we see is lit.
Waning gibbous lasts from Full Moon to Third Quarter, so it lasts about 7 days.
No, a 'gibbous moon' is part of the regular lunar cycle. The moon takes roughly 30 days to go from a new moon, through all its phases, to become a new moon again. For a little under 3/8th of this time, the moon will be a gibbous moon, which will either be waxing gibbous towards a full moon and waning gibbous away from it.
The "more than 50%" moon is called the gibbous moon. When it is "growing" (appearing to get larger), it is a Waxing Gibbous; when "shrinking," it's the Waning Gibbous.
about 8 days
no
We see more of the moon lit when it is a gibbous moon than when it is a crescent moon, so it does seem bigger. Save
