Ocean phenomena refer to various natural events and processes that occur in the ocean. These include currents, waves, tides, and upwelling. For example, ocean currents are large-scale movements of water that can influence climate and marine life. Tides are caused by the gravitational pull of the moon and sun, leading to regular changes in sea levels. Another fascinating ocean phenomenon is El Niño, a climate pattern that affects weather worldwide. It occurs when warm water in the Pacific Ocean disrupts normal weather patterns, leading to increased rainfall in some areas and droughts in others. Understanding these phenomena is crucial for predicting weather and managing marine resources.
