As the clouds reach the saturation point, water droplets will form, which come as rain. This rain runs off the land and collects into bodies of water, where the whole process begins repeatedly. Water can also be found on the surface of the earth. Only 4% of the water stays on the earth's surface. Surface waters include aquifers, lakes, ponds, reservoirs, rivers, streams and wetlands or the blue waters which hold only about .3% of the Earth...
