The shape of the lighted part of the moon is called the "phase" of the moon. The phases of the moon change as it orbits Earth, transitioning from new moon to full moon and back to new moon in a cycle lasting about 29.5 days.
When the lighted part of the moon grows it is a "waxing moon".
It's always the same moon, but the shape of the visible lighted portion changes. Whatever shape of the moon you see right now, you'll see the same shape again after 29.53 days have passed.
No, during a full moon, we see the entire lighted side of the moon, whereas during a new moon, the lighted side of the moon is facing away from Earth so we see no lighted side at all.
There is always a moon - it is our satellite, and is always visible somewhere. The moon "shape" is caused by the sunlight shining on it, and we see different lighted areas depending on where the moon is in relation to the earth.
a new moon is when the moon is forming again and a full moon is when the moon is fully formed <><><><><> The new moon is when the Moon is minimally lighted, while the full moon is when the Moon is maximally lighted.
This is what causes the so-called "phases" of the moon: although fully half of the moon is lighted, we can only see part of the lighted part. A person on earth hardly ever sees all of the lighted side of the moon. When he does, he calls the sight a "full moon."
Not exactly. The lighted side of the moon as seen from Earth is that part that is not shadowed by the Earth.
The moon is said to be waning, when the lighted part gets smaller. When it gets larger, the moon is waxing.
the lighted half is facing towards the sun not the earth
