It doesn't
semilunar valves are called semilunar because they look like half a moon. If something is not full in biology it is called 'semi' and lunar means the moon. So basicaly its called that because the valve looks like a half moon.
the moon is always spherical, it's just the way the clouds are and how you look at it.
No. The moon does not have an atmosphere.
The moon circles the Earth approximately every month. It takes 27.3 days for the moon to make one orbit around our planet. Even though it looks like the moon is moving from East to West, it actually isn't. It's moving from West, to East. If you go outside and find the moon, look at the stars behind it. Go outside the same time the next night and the moon will be noticeably East from where it was the night before. :) That's also why the moon rises almost an hour later each night.
the moon do have a equator, just like Earth.
The moon because the earth bulges at he equator so its like a disk, so the moon is rounder
what did the moon look like on Nov.19,2017
At the equator (around the middle, as we look at it) the Moon measures 6,395 miles - 10,921 kilometres.
The moon was a fool moon\
Yes, the Moon can be seen from the equator. The Moon is visible from all locations on Earth where the sky is clear and the Moon is above the horizon.

An equator is simply an imaginary line across the middle of the planetoid. So yes, the moon has an equator.
Generally speaking, if you live in the Northern Hemisphere, the sunlit portion of the moon will move from right to left (i.e. a first quarter moon will look like a capital D and a third quarter moon will look like a reverse capital D). In the Southern Hemisphere, the sunlit portion of the moon will move from left to right (the first and third quarter moons will be lit on the opposite sides as when viewed from the Northern Hemisphere). In countries near the equator, it is a lot harder to ascertain waxing and waning moon phases but the first quarter moon will look like a lowercase n when it rises and an uppercase u when it sets, likewise the third quarter moon will look like an uppercase u when it rises and a lowercase n when it sets.
