Water Drops: Science & Hydrology

Everything you ever wanted to about water in a 5-set series of 90-second podcasts from renowned hydrologist, Peter Black.
Black explains, "Water is life. That's why water has fascinated me so much for so many years of my life. I have spent my whole adult life studying and teaching about water in our environment. I want to share some of my wonderment of what water is and how it behaves; how we use it; how we try to control it; and some fun things about it that you can see yourself. Water is really a most astonishing substance. It exists at normal temperatures as a gas, liquid, or solid. It's the basis for life on this planet. It's the reason earth looks like a big, blue marble in all those wonderful pictures we now take of ourselves from space. It's what we're looking for on Mars and other planets because we believe it's the only way we'll find life in other parts of the universe." continued Black.
Black said, "Water is also the center of our personal universe; the human body is mostly water. The body uses water to cool us in hot weather but perspire too much without replacing that water and we suffer hypothermia." In fact, Black points out, we can live a lot longer without food than we can without water.  Also, water is needed to grow food; manufacture products; transport goods around the world; produce electricity; extinguish fires; and have fun like fish; boat; ice skate; and ski."
