Introduction
Have you ever wondered why the sea level rises and falls throughout the day? This WebQuest will take you on an exciting journey to discover the mystery behind ocean tides — how the Moon and Sun affect them, and why they matter to people living near the coast. By the end, you will understand how tides work and why they are important for navigation, fishing, and coastal life.
Task
