Water Factoids

• Every year, 80,000 cubic miles (330,000 km³) of water evaporates from the oceans.
• Every year, about 15,000 cubic miles (63,000 km³) of water evaporates from the Earth's land sources.
• About 95,000 cubic miles (400,000 km³) of water are moving between the Earth and sky at all times.
• Only about 24,000 cubic miles (1000,000 km³) of water actually get to the land as precipitation.
• Land precipitation averages 26 inches (660 mm) a year.
• Some places, like deserts, get less than an inch (25 mm) of water a year; while others, like tropical rain forests, may get more than 400 inches (10,000 mm) a year.
