Introduction
Have you ever wondered why the ocean water rises and falls every day? What force is powerful enough to move the sea? In this WebQuest, you will become a young scientist and discover how the Moon and the Sun influence the movement of Earth’s oceans. By the end of this journey, you will be able to explain ocean tides in your own words and show how they affect people’s daily lives.
