The Journey of a Raindrop: sky to soil

Introduction

Have you ever wondered where a raindrop comes from, where it goes after touching the ground, and whether it might one day fall as rain again? What appears to be a simple drop of water is actually part of one of nature's most remarkable journeys.

Water is essential for life. It sustains people, supports agriculture, nourishes ecosystems, and drives countless natural and industrial processes. Although approximately 71% of the Earth's surface is covered by water, most of it is saline water found in the oceans. Only a small proportion is freshwater, and much of that is locked away in glaciers, ice caps, or underground. The amount readily available for human use is therefore limited.
