Because the moon goes through phases that allow you to see certain parts of the moon at a time. Theses phases are the following:
1. The New Moon.
2. Waxing Crescent.
3. First Quarter.
4. Waxing Gibbous.
5. Full Moon.
6. Waning Gibbous.
7. Last quarter.
and the
8.Waning Crescent.
. You see the phases because as the moon orbits the earth, the sun is shining on various areas of the moon.
on a moon less night.
It probably came quite naturally, because the Moon (a) is easy to see, and (b) has a more or less regular period.It probably came quite naturally, because the Moon (a) is easy to see, and (b) has a more or less regular period.It probably came quite naturally, because the Moon (a) is easy to see, and (b) has a more or less regular period.It probably came quite naturally, because the Moon (a) is easy to see, and (b) has a more or less regular period.
After the full moon, we see less and less of the sunlit side.
The new Moon "phase" is when the Moon is (more or less) in front of the Sun. We cannot normally see the Moon in this phase. If the Moon is exactly in front of the Sun, the Moon covers the Sun and we see a solar eclipse.
At new moon, the Moon is right next to the Sun - that is, you see it in the same direction, more or less. At new moon, the Moon rises together with the Sun.
Why not? If they happen to be more or less in the same direction, you'll see both.
After a waning moon one gets a new moon.
The sun reflects light off the moon at all times. The moon is always revolving, so eventually you see less and less until you see nothing. When you don't see the moon, its called a new moon.
its called a waning
Like the Earth, the Moon is a sphere which is always half illuminated by the Sun, but as the Moon orbits the Earth we get to see more or less of the illuminated half.
the moon waxes (gets full) and wanes (gets thin) because of the position of its 28 day orbit around the earth. The as the moon orbits, the sun reflects off more or less of it, so you see more or less of it.
The phase of the Moon during which more than half, but less than all, of the visible hemisphere of the Moon is illuminated by sunlight. A gibbous moon is between a full moon and a half moon, or between a half moon and a full moon. There can be two gibbous moons: waxing and waning. " A gibbous moon is one of the phases of the Moon when the size of the illuminated portion is greater than half but not a full Moon. The period between a first quarter moon and a full moon is known as a waxing gibbous moon, because the illuminated region of the Moon is increasing from day to day. After it becomes a full moon, but hasn't reached the last quarter, the Moon is called a waning gibbous moon."
