Phases of the Moon
What causes the phases of the moon? The moon's revolution around Earth.
The apparent shape of the moon depends on the changing positions of the Earth, moon, and Sun
27.3 days How long does it take for the moon to revolve around Earth ? One complete orbit of the moon around The Earth takes? ESRTs p15
One complete cycle the moon’s phases takes 29.5 days Explain why there is a 2.5 day difference Because you need to go back to the first phase that takes another 2.5 days
27.3 days How long does it take for the moon to revolve around Earth ? One complete orbit of the moon around The Earth takes? ESRTs p15
What phenomenon does this explain? We only ever see one side of the moon.
Why does the moon rise later each day? because as the Earth rotates, the moon revolves
