Create an ocean procedurally with simple geometry node set up without too many math nodes

If you are someone who want to create a ocean procedurally, but got confused because of many math nodes in the workplace, here's the solution, you don't have to use all those math nodes to do this.You create ocean geometry without to many nodes, if use the correct nodes.

if you use join geometry, and more node set ups, you can create foam, tornado..... a lot more.

Just because geometry node is functioning with math, you don't have to be a math expert!!! Don't lose hope!!!!!
