Why are there high tides on the opposite side of the world at the same time?
[This image explains it well](_URL_0_). Basically, tides are caused by the moon's gravity. The closer something is to the moon, the more it is affected by its gravity.
The Short Answer
[This image explains it well](_URL_0_). Basically, tides are caused by the moon's gravity. The closer something is to the moon, the more it is affected by its gravity. So, the part of the ocean closest to the moon is pulled towards it, causing high tide. However, the part of the ocean farthest from the moon is not pulled towards it as much as part of the oceans in the middle, causing another high tide. The fact that the influence of gravity can change so much over such a short distance is cool. In some extreme cases (like the moon Io around Jupiter), these "tidal forces" caused by the different amounts of gravity can actually stretch the ground and cause it to heat up. On Earth, it just sloshes our oceans around… but on Io, it causes the entire moon t have constant volcanic eruptions.
