That's Correct!
It's Wrong!
Most coastal areas experience two high tides and two low tides each day, resulting in four tidal changes every 24 hours. These tides are primarily caused by the gravitational pull of the Moon and, to a lesser extent, the Sun on Earth's oceans. The interaction between these gravitational forces and Earth's rotation results in the regular rise and fall of sea levels, known as tides. Tides are important for various ecological processes, including the movement of marine species and the health of coastal ecosystems. Additionally, they have significant implications for human activities, such as navigation, fishing, and coastal management.
