Why is the earth called the water planet?
Why is the earth called the water planet? A – Water or glaciers cover about 80 percent of this planet. But only 3 percent is freshwater (containing no salt). Most of the freshwater is frozen in glaciers at the North and South Poles. That leaves 1 percent of the freshwater for our use. That’s all we’ll ever have to use. So you can see that water is a very precious resource on earth. Q – What if the glacier ice at the North and South Poles melted? A – Scientist have been talking for years about how nice it would be if an iceberg could be towed to places where fresh water is needed. They estimate that if the ice caps melted, the present sea level would rise over 200 feet. That would cover many seashore communities which are below the 200 feet sea level mark. But the earth’s temperature at the North and South Poles would have to rise considerably before this would happen. Q – With so many of us using the water, will we ever run out ? A – About 700 billion gallons of clean drinking water is
