Class 5 Science ยท Earth and space

Why does the Moon change shape every night?

How ClarifyBro explains it, scene by scene:

  1. 1
    The Moon makes no light

    It only reflects sunlight. Half of the Moon is always lit by the Sun.

  2. 2
    The Moon goes around the Earth

    One trip takes about 29.5 days, so our view of the lit half keeps changing.

  3. 3
    New Moon

    The lit half faces away from us, so we see almost nothing.

  4. 4
    Crescent, half, gibbous

    As the Moon moves, we see more of the lit half each night.

  5. 5
    Full Moon

    The whole lit half faces us. Then it shrinks again until the next New Moon.

Answer The Moon does not change. We see different amounts of its sunlit half as it orbits the Earth.
