Week 3 Prompt

At the top is my original question, answer, and picture to help solve the answer. The answer I gave was okay but I would like to elaborate on that answer. The sun's gravity affects tides because first of it is the prime mover of tides. In all the sun only affects 45% of the movement of the tides. Next is the moon's gravity. The moon is known to have a greater affect on  tides than the sun because the moon is a whole lot closer to the earth than the sun is. Even though the sun's gravitational pull is larger on the earth it's influence on the tides is not as strong as the moon's. The affect of the certain gravities can be determined by the earth's tilt. Now with all that said I think I have come to the conclusion that the moon's gravity has a greater affect on the Earth's tides.

    On your open ended I really liked it not only because it was well written but also because it was very detaileed and you were very specific on what and how you wrote it!
