Introduction
Introduction
Have you ever wondered why the water level of the ocean rises and falls? These changes are called tides. The Moon, the Sun, and the Earth all play important roles in creating tides. In this WebQuest, you will explore reliable online resources to understand how tides happen and why they are important to people and the environment.
