![]() ![]() From our view point, on a spinning Earth, the Moon appears to wobble from side-to-side. So we see the Moon rise and set, just like the Sun. At which lunar phase(s) are tides most pronounced (for example, the highest high tides) A) both first and third quarters B) third quarter Moon only C) both new and full Moons D) new Moon only E) full Moon only. Secondly, the Earth is rotating on its axis. occur at new and full moons, and have the highest high tides and lowest low tides. High tides are highest at first- and third-quarter moon. At which lunar phase are tides most pronounced both new and full moons. ![]() Because of the tilt of the Moon's axis, this speed change looks like a slight movement from side to side in the east-west direction. High tides are highest at both full moon and new moon. Tides are caused by the difference in the force of gravity exerted by the moon across the sphere of the earth. When the Moon is closer to the Earth, it moves faster when it is further away, it moves slower. The community assemblages were most pronounced immediately before or after the spring tide diatom bloom, but not during. Firstly, the Moon orbits the Earth in an oval or ellipse, not a circle. An oval orbit means the distance between the Earth and the Moon changes during its orbit. Two things cause the movement from side to side. This tilt means that at some times in the month, we can see past the north pole of the Moon, then later in the month, past the south pole. Just like the Earth is tilted by over 20 degrees on its axis with the Sun, giving us seasons, the Moon's axis is also tipped by about 5 degrees compared to the Earth. How long does it take to complete each orbit, and how do we know C) Each orbit takes about 1 year, which we know from Keplers third law. The movement up and down (in latitude) is due to the tilt of the Moon's axis. It moves both up and down and side to side. The wobble is most obvious if you take a picture every night and then stitch them together into a video. Over a lunar month, the Moon wobbles slightly in the night sky. The moon pulls harder on one side of Earth than the other, stretching Earth like a rubber band and causing high tide on the side closest to the Moon and the side farthest from the Moon. You would think that this meant that we could only see 50% of the Moon's surface, but we can see slightly more from Earth. The Moon is locked with the Earth, which means that we always see the same side of the Moon.
