One morning in New York City at 9:AM, Larry looks south and sees the moon is due south.
A. Draw a sketch of the appearance of the moon for Larry and identify the phase. Explain how can you tell.
B. At the very same moment, Moe is in Pittsburgh (about 500 miles due West). In what way will Moe's observation be the same as Larry's and in what way will it be different? Explain your reasoning.
C. At the very same moment, Curly is on the moon looking at the Earth. Use your physical model to describe what Curly would see when looking towards the Earth. Explain your reasoning.
D. Suppose Curly were to look at the Earth again 7 days later. What would the apparent shape of the Earth be? Explain your reasoning.
