Introduction
With over 70% of the Earth being covered with oceans one has to be interested in learning about them. Learning about the medium to which all life on Earth sprung from. It is important and it is mysterious, we know more about the surface of the moon then we do about the contents of our oceans.

Why do waves crash?
Waves crash because their amplitude does not change as they reach the shollowing shoreline. Therefore as they reach the shore they seem to get taller because they remain the same size but are forced upwards by the shollowing shoreline until they cannot maintian their shape and crash over themselves.
Next we'll look at tides.
