Label the compass directions north, south, east and west on Figure 1 at appropriate locations at the edges of the disk that represents the edge of the horizon. This checks whether you really understand the diagram, and what represents the horizon. Thus, if you are not so sure about to answer here, then you clearly need to ask for some more guidance in understanding the celestial sphere model!. The moon is the largest and most striking object in the night sky, and it would behoove most Earth residents to have a good understanding of its phases. The purpose of the first exercise here is to first promote an understanding of why we see the various phases of the moon, and to provide rationale for what we see from the Earth. Thus, you will not be trying to draw the phases as you see them from Earth. Instead, the diagram below represents a top view of the earth-moon system, as viewed from above the Earth's North Pole. It's designed to analyze the various moon positions during the Moon's month long orbital period. The dot on the central circle represents the north pole of the Earth, and the dots in the center of the other outer ten To bi Miche ar circles represent the north pole of the moon. The arrows indicate the direction from the Sun, and therefore the direction the sunlight is coming from. Refer to this diagram for question 1. It is important to understand that, of course, the Earth spins here. Thus, where in the sloy the moon.
