Understanding Ocean Tides

Introduction

Have you ever wondered why the sea rises and falls every day?

Imagine standing on the shore in the morning and returning later to find the water has moved far away—or come much closer!

In this WebQuest, you will explore the science behind ocean tides and discover how the Moon and Sun influence our oceans. By the end, you’ll become a “Tide Expert” ready to explain this natural phenomenon.
