Exoplanets and Tides
... The oceans are not uniformly spread over the globe. There are continents sticking up, deep and shallow parts, etc. This complicates things, but tides can be reliably predicted. The Sun also raises tides. But it is at a much greater distance (400x as far away), so its tides are less important than th ...
