Quizplus · Accepted Answer

The Earth's surface is 30 percent land and 70 percent water. The vast majority of that water-over 96.5 percent-exists in oceans, seas and bays. Roughly half of what remains (1.74 percent of a remaining 3.46 percent) exists in ice caps, glaciers and permanent snow. Another 1.69 exists in groundwater. The remaining .03 percent is divided among soil moisture, ground ice, permafrost, all lakes, the atmosphere, swamps, all rivers and all of the biological life forms on the planet.
