The moon is said to be waning when less and less of the side facing Earth is lighted. :D
The sun shines more or less directly on parts of the earth as a function of the earth's axial tilt relative to the ecliptic, and of the earth's diurnal rotation on its axis.
The only way is to move farther away from Earth.
It is less than mars
No. Landmasses cover less than 1/3 of Earth.
A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.
"Waning" means that less and less of the moon's lighted side is visible from Earth as time goes on. That's what's happening during the entire two weeks from Full Moon until the next New Moon.
The motion of the moon in its orbit, which takes it to positions where we see more or less of the moon's lighted half from earth.
Those shapes, and the corresponding phases, are called "crescents" ... when the lighted part that we see is less than half of a full disk.
A waxing gibbous moon appears high in the east at sunset. It's more than half-lighted, but less than full.
Waning
the moon goes through the same phases but in reverse sequence, less and less of the lighted side of the moon faces the earth until the moon disappears.

A waning moon
No, not directly. But in an indirect way the phase of the Moon will be affecting the tides and different phases of the Moon means it give of more or less light depending on the phase.
A2. The Moon keeps one side locked towards Earth. Thus whether it were illuminated or not, we can never see the far side of the Moon.Incidentally, there is a marvellous movie of the complete Lunar cycle under Moon/Tidal effects in Wikipedia.A1. The sun casts a light on one side of the moon and the other side is a dark shadow. So if there is a half moon, for example, from earth, we can see half of the lighted side and half of the dark side, which makes it look like the moon is cut in half. Since the Earth rotates, we can see a different side every night, and that's how we can see more or less of the lighted side of the moon. For a new moon, Earth can see the whole dark side and none of the lighted side. For a full moon, Earth can see the whole lighted side and none of the dark side.
Because the part of the Earth you are on is not facing the Sun at that time. The earth is continuously rotating, so at any time, part of the Earth is facing the Sun and part is facing away from it. The part facing it is getting lots of light, so it is day time and the part facing away gets less light, so you have darkness and it is night time.
The moon is always half lit as it revolves around the earth. When the moon is directly between the earth and the sun we can not see the side that is in sunlight because it faces away from us. As it continues to rotate around the earth we see more and more of the lighted side of the moon. When it finally gets to the point directly opposite the sun, we see the whole lighted moon, or the full moon. As it continues to rotate we see less and less of the lighted side until it is again directly between earth and the sun, and we see no moon at all: the new moon, or dark of the moon. It takes 14 days for the new moon to become a full moon, so it would take about 12 days for a crescent moon to become full.
