how are waves caused?

Question

i mean i know that it has something to do with the moon but how exactly

Answer 1

The water of the oceans is in constant motion. The gravitational pull of the sun and moon oscillates the surface of the oceans twice a day while the wind agitates it into waves.
The surface of the sea exerts a frictional drag on the bottom layer of a wind blowing over it, and this layer exerts a frictional drag on the layer above it, and so on. The top layer has the keast frictional drag exerted on it which means that the layers of air move forward at different speeds. The air tumbles forward and finally develops a circular motion. This motion causes a downward pressure (DP) on the surface at its front, and an upward pressure (UP) at its rear, and this causes the surface to take on the form of a wave.
The back of the wave tumbles forward but it moves back later and slows the forward movement at the front of the wave. The wave now grows bigger. hope this helps if you want more info or diagrams the website is below

Answer 2

Tides are caused by the moon. The waves are casued by wind. Try searching "Fetch" i think it is something to do with that.

Answer 3

Also has to do with how the coast is and how it was formed naturally...There are different points on a coast. I won't look it up and tell you, I think you are capable. I know one is the "Continental Coast" :) god its been years since I learned about this
