This site explains what tides are and the difference between Proxigean Spring Tides, spring tides, and neap tides, and how these are formed. Graphic illustrations are provided.

Why does the Moon always shows the same face to the Earth? Why is the Moon's rotation period the same as the length of time it takes to orbit the Earth? Why are there two tides a day? These questions and more are answered here.
