Phases of the moon
The moon is not visible on Earth. This phase is called the new moon.
how did the moon form?
.Scientist long thought that a figure the size of Mars smashed into our planet Earth about 4.5 billion years ago. They believe that debris from this smash put together to form the moon.
why is the moon our natural satellite?
.The moon is a fairly weird rocky object. Its light is really only the reflected sunlight, dim reflected light from our planet Earth is occasionally visible on the part that is not lit by the sun.
The Moon and our planet Earth, are like pairs of masses in the universe, gravitation is drawn to one another. The strength of this force decreases with length, so the Moon pulls stronger on the side of Earth closest to it than it does on the far side
.A couple or multiple days after the new moon, as the moon moves longer in its orbit, a small part of the side of the moon becomes lit and able to see. This is referred as the crescent moon.
.When the moon moves father in its orbit, the crescent waxes, or gets bigger. When half the side that is lit is able to be seen, this phase is called the first quarter this is because the moon has moved through one quarter of its orbit.
.The phase that is next is the gibbous moon, what happens here is more than half the side that’s lit is visible.
.The Moon’s sometimes large size brings its self a significant influence on our planet Earth, the most of the evidence is in the ocean tides, which actually is a result of the Moon’s gravitational pull on our planet Earth.
.The gibbous is followed by the full moon.
.One observation is that the first hit created two moons- which later smashes into one another. This hit may have caused the smaller moon to flatten out and stick into one moon that was larger.
