The different phases of the moon are caused by the relative positions of the sun, Earth, and moon. As the moon orbits Earth, the angle between the Earth, sun, and moon changes, causing different portions of the moon to be illuminated by sunlight, creating the various phases. The moon's orbit is slightly tilted compared to Earth's orbit around the sun, which is why we see the different phases as the moon moves in and out of Earth's shadow.
Yes, exactly. The part of the Moon we see bright is the part that is exposed to direct sunlight.
The changing shapes of the moon, known as its phases, are due to its position relative to the sun and Earth. As the moon orbits Earth, the amount of sunlight that reflects off its surface changes, creating the appearance of different shapes or phases from our perspective on Earth.
Yes, people can only see the part of the moon that is illuminated by the sun, which is why the moon appears to change shape throughout its cycle. The side of the moon facing away from the sun is in darkness.
The part of the moon that is always in sunlight is the "near side" of the moon, which faces Earth and receives light from the sun. This is the side that we see from Earth, as the moon rotates at the same rate that it orbits Earth, keeping the same side facing us.
