They exist as a way of getting water carried to the beach by breaking waves back out to sea and are usually confined to deeper channels between shallow sand bars The bigger the waves the stronger the rip Think of them as rivers of the sea Low energy They are caused by both natural and man made sources There is no identified linkage between earth currents and any human disease Key Points Earth currents arise from both natural and man made sources including the magma in the earths core solar fla Vocabulary.
