I assume wind is also a factor but would the gravitational pull of the moon be the main force behind the oceans tides? To be honest I have no idea what even causes the wind so go easy on me if that was a dumb question.
It is indeed the "pull" of the moon "lifting" water. It has nothing to do with orbits per se. Suppose the Moon's orbital angular momentum with respect to the Earth suddenly vanished. That would have zero instantaneous effect on the tides.Frame Dragger said:Finally, it's not just the "pull" of the moon "lifting" water... it's interaction between two fairly large masses (remember the moon is about 1/4 the mass of the Earth... no slouch), and the sun plays its role on a slower scale reflecting the period of our orbit around it.

BTW, the Moon's diameter is about 1/4 that the Earth. It's mass is considerably less than that of the Earth. The Moon's mass is about 0.0123 that of the Earth.
Jonathan Scott said:The tricky thing is understanding why there is a high tide on the opposite side to the moon as well as on the near side.
The moon causes tides through its gravitational pull on Earth's oceans. The moon's gravity pulls the water towards it, creating a bulge on the side of the Earth facing the moon, and a corresponding bulge on the opposite side due to the centrifugal force.
Yes, the moon affects all tides on Earth. However, the sun also plays a role in tides, with its gravitational pull causing smaller but still noticeable tides.
Yes, the moon's position in its orbit does affect tides. When the moon is at its closest point to Earth (perigee), its gravitational pull is stronger and creates higher tides. Similarly, when the moon is at its farthest point from Earth (apogee), its gravitational pull is weaker and creates lower tides.
Yes, besides the moon's gravitational pull, tides can also be affected by the shape of the coastline, the depth of the water, and the Earth's rotation. These factors can cause variations in the height and timing of tides.
No, tides do not always follow the same pattern every day. The moon's orbit around Earth and Earth's rotation can cause variations in the timing and height of tides. Additionally, other factors such as storms or strong winds can also affect tides on a daily basis.
