Moon's orbit around Earthis not perfectly round but is oval or elliptical in shape. As the Moon orbits our planet, it's distance varies from about 221,000 to 252,000 miles. This 13% variation in the Moon's distance makes the Moon's apparent size in our sky vary by the same amount

The orbit of the moon around the Earth, and how that changes the position of the Sun relative to the Earth-Moon axis.

because of the location of the moon with respect to the sun and earth.

The sun shines light. The Moon is illuminated. From Earth an observer sees a sphere (the moon) illuminated from different angles (phases of the Moon).

At any moment, half of the Moon is illuminated by the Sun, the other half is in the darkness. The idea is that sometimes, we see only the illuminated half - full moon. At another moment, we see the dark side, and perhaps a very small portion of the illuminated part - new moon. At other times, we see part of the bright side, and part of the dark side.

The rotation and revolution of the moon around the earth causes it to show phases when viewed from our planet.

No. The rotation of the moon has nothing to do

with the 'phases' seen from earth.

What do you call the changing appearance of the moon?

The Moon's phases.


What is the changing appearance of the moon from earth?

Moon Phases!


What is the Moon's changing appearance called?

Phases.


Why does the Moon's appearance keep changing?

because the light on the moon is reflected by the earth so when the earth is not facing on the moon there is not that much light


Changing appearance of the moon as seen from the earth?

moon phases


Which motion causes moon changes?

The motion of the Moon orbiting the Earth, and the Earth and the Moon both orbiting the Sun, constantly alters the appearance of the sunlight striking the Moon's surface, as viewed from Earth. This changes in light and shadow gives the different phrases of the Moon.


What the changing in appearance of the moon as viewed from the earth due to the relative positions of the moon earth and sun?

Phases, a phase depends on how much of the sunlit side of the moon faces.


Does the moon change from night to night?

The appearance of the moon changes from night to night because different parts of the moon are illuminated by sunlight, from the perspective of the viewer here on Earth. The moon itself is not changing, it remains the same.


What causes the changing appearance of the moon?

The moon changes in appearance from the perspective of people on Earth because it is revolving around the planet and Earth is revolving around the Sun. When the Moon and Sun are on the same side of Earth, we do not see the moon because the side that is illuminated by the Sun is pointing away from us. This is called the new moon. When the moon is on the opposite side of Earth two weeks later, (Earth is between the Moon and Sun) the illuminated side is pointing toward us and we see the whole side of the Moon lit up. This is our full Moon. Everything else is during the times when the Moon is becoming full or becoming new again. Unfortunately I can't draw a diagram on this site but you can check out any good astronomy book or website to find one.


Why moon is changing its shape?

The moon is not changing it's shape!


What fundamental force is responsible for tidal?

Gravitational force between Earth - Moon - Sun is the fundamental force behind the tidal motion.


Is gravity responsible for phases of the moon?

Yes, The force of gravity is responsible for the orbiting motion of the moon about the earth and also the motion of both the moon and earth around the sun. The orbital patterns of the earth and moon cause their positions to be relative to the sun in a way that repeats itself every 29 days - a full phase. The light that bounces off the moon and back to someone on earth depends upon the position of both, relative to the sun. So since gravity causes the pattern of the orbits then it is responsible for the phenomenon.
