    Answer 5 out of 7 questions correctly.

Most coastal areas on Earth experience tides. Tides are daily changes in the ocean's water level. High tides happen when the water level rises, and low tides happen when the water level falls. Tidal changes are especially visible at places like the beach. For example, a sandcastle built near the water's edge during low tide will likely be washed away by the rising high tide later in the day.
