Bill Nye the Science Guy (1993)

Episode Overview

Approximately 70% of our planet is enveloped in water, much of which has existed since the Earth’s inception billions of years ago. This implies that the water in your glass today might have once been enjoyed by a dinosaur. Water is perpetually cycled through various forms such as rain, snow, sleet, and hail, moving through oceans, lakes, rivers, and glaciers. This ongoing process of water transformation and movement is known as the water cycle. Pretty fascinating, right?
