Understanding Ocean Tides

Introduction

The ocean is constantly moving, rising and falling in a rhythm called tides. Understanding tides helps us predict high and low water levels, plan beach activities, and even understand marine life behavior. In this WebQuest, you will explore what causes ocean tides, identify high and low tides, and learn about the Moon’s role in creating them.
