Tidal phenomena refer to the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun on the Earth's oceans. These changes in water level, known as tides, occur in a predictable pattern, typically twice a day, leading to high and low tides. The alignment of the Earth, Moon, and Sun influences the strength and timing of these tides. Different coastal areas experience varying tidal ranges due to factors like geography, ocean currents, and weather conditions. Some regions may have minimal tidal changes, while others, like the Bay of Fundy in Canada, experience some of the highest tides in the world. Understanding tidal phenomena is essential for navigation, fishing, and coastal management.
