What are the causes of waves in the beach (near sea shore)?

This is the main cause to form a wave over the sea surface. Winds are primary energy source for currents that flow horizontally in the ocean surface layers (less than 100 to 200 m deep). read more

Sea foam forms when dissolved organic matter, dissolved salts, and algae etc. are mixed caused by wind and waves. Algal blooms are a common source of sea foams. When the blooms decay, the decaying matter often washes ashore causing foam. read more
