Ocean levels refer to the height of the ocean's surface, which can change due to various factors. These factors include tides, which are caused by the gravitational pull of the Moon and Sun, and seasonal variations in temperature and precipitation. Additionally, ocean levels can rise or fall due to climate change, which affects the melting of ice caps and glaciers. Rising ocean levels are a significant concern for coastal communities. As global temperatures increase, polar ice melts, contributing to higher sea levels. This can lead to flooding, erosion, and loss of habitat for both wildlife and humans. Monitoring ocean levels is crucial for understanding and addressing these environmental challenges.
