Why there is a phases the moon?

Answer 1

-- At any time, 50% of the moon is illuminated by the sun.

-- As seen from Earth, the moon moves in a path around us.

-- The position of the moon on its path around us determines

how much of its lighted half we can see from where we are.

. . . If the moon is behind us, directly opposite the sun,

then we can see its complete lit-up half.

. . . If the moon is off to our side, then we can only see

about half of its lit-up half.

. . . If the moon is in front of us, in the same direction as

the sun, then all we can see is its dark back-side.

Answer 2

== == At any given time, the half of the moon facing the sun will appear bright, and the half of the moon facing away from the sun will appear dark. The moon makes one complete orbit of the earth every 28 days, and as it goes around we see more or less of the bright side.

The classic experiment for showing how this works is to use a lamp or flashlight and a ball. The flashlight represents the sun. Put it on a shelf on the opposite side of the room, pointing towards you. Your head represents the earth, and the ball represents the moon. Stand holding the ball up in front of you, and slowly turn around on the spot. Watch how the flashlight shining on the ball is similar to the changing phases of the moon.

Answer 3

The Moon phase in, in my school, called a "moonth." It takes 28 days for the Moon to spin around in a circle and revolve around the Earth. The Moon phase goes like this: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent. They happen because the moon revolves and the sun reflects light onto it. The lit part of the moon is the moon phase, or what we see from Earth. All parts of the Earth see the same moon phases because the moon spins at the same rate as it revolves.

Answer 4

The moon has different phases because it rotates around the Earth. We only ever see one side of the moon, no matter where we are on the Earth. Depending on its position to the Earth, a certain amount of light will be shone onto it by the sun. With a full moon, the light from the sun is shining completely on the side we can see, and where there is no moon the light from the sun is shining on the side we can't see. The moon takes 28 days to orbit the Earth once, meaning each moon cycle takes 28 days.

Answer 5

Depending on the Moon's position (its angle in the sky, relative to the Sun), at one time, we see the bright side of the Moon (full moon), at another time, we see its dark side (new moon), or anything in between.

Answer 6

we see the mood phases according to the sunlight flashed on the moon and it varies to its position, and how it rotates and revolves around the earth.

Answer 7

Half of the Moon is always illuminated by the Sun (barring lunar eclipses). The phases result from how much of that illuminated side we can see from Earth.

Answer 8

The moon actually is 65 percent lit anywhere on the moon.

Answer 9

Because the Moon orbits the Earth at least once each month.

Answer 10

at night, the light of the sun is on the other side of the world, so every day it will mive. like the earth.
