the moon waxes and wanes as the earth moves and blocks certain rays of suns from hitting the moon. The moon, which doesn't put of any light of it's own, reflects what light hits it and we can see those sections, but the other parts which the earth is blocking the sun from it, we can not see.
wax and wane
xx
rise set wax wane
The revolving of the earth and the rotating of the moon.
the earth blocks it from the sun
During the time at sea, the sailors saw the moon wax and wane three times.
Two weeks, and two weeks to wane.
Wax and wane
That completely depends on when you start watching it. The question is like asking: "Does it get light or dark outside first ?"
It's the earth shadow
The opposite of to wax is to wane. Wax means to grow and wane means to diminish
Yes it does because it revolves around the sun
