Sea level is the average height of the ocean's surface or the midpoint between mean high and mean low tide. This measurement helps us understand fluctuations caused by various factors like atmospheric pressure, ocean currents, and gravitational forces from the moon and sun. Knowing this average is crucial for coastal planning and environmental assessments. Interestingly, while sea level may seem static, it actually varies across the globe! Some areas experience higher sea levels due to ocean currents and wind patterns. These differences in sea level can affect navigation, marine ecosystems, and coastal communities. It's a dynamic system influenced by many factors!
