Marea is a term that refers to the natural phenomenon of tides, which are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun. These forces create bulges in the ocean, leading to high and low tides that occur approximately every six hours in most coastal areas. The strength and timing of Marea can be influenced by various factors, including the shape of the coastline, the depth of the water, and local weather conditions. Understanding tides is essential for activities such as fishing, boating, and coastal management, as they affect navigation and marine ecosystems.
