Water comes from three main natural sources: rain water, underground water and surface water. Rain water includes rain, snow and other forms of precipitation. Underground includes water tables and water hidden in the soil. Surface water includes oceans, rivers, lakes, ponds and any other above-ground collection of water.Know More
These natural sources of water supply most of the water for the planet. Precipitation replenishes underground and surface water supplies and is a key part of the water cycle. Underground water sources are not immediately accessible but are one of the most important sources of water for human consumption. Underground water supplies are accessed through wells, or from springs when the pressure gets too great.
Surface water is the easiest to access and the most abundant, though most surface water is salt water, and, therefore, not suitable for drinking by most species. Surface water is used for drinking and for producing hydro-electric power as a renewable, clean energy source. This water comes from precipitation, springs and the melting of glaciers. Rivers eventually empty into the ocean.
A large portion of fresh water is trapped in glaciers, the ice caps and the atmosphere. The frozen water is not accessible directly by humans, but it does help to replenish surface water supplies as the global temperature rises and the ice melts.Learn more about Bodies of Water
Water waves are generally classified as deep-water waves or shallow-water waves. Deep-water waves are produced through oscillation, occurring when the water depth surpasses half the length of the waves. Shallow-water waves meanwhile, are generated through translation, occurring when the depth of water is less than 1/20 of the length of the waves.Full Answer >
Salt water pools irritate a swimmer's skin and eyes less than traditional chlorinated pools. Salt water pools also have less of a pervasive odor and are gentler on swimsuits. Some experts believe that salt water pools are more eco-friendly and healthier than chlorinated pools. At the same time the salinity level is fairly low, considerably less than that of the ocean.Full Answer >
There are several different types of natural water forms within and around the Philippines, including channels, swamps, straits, gulfs, seas, bays, waterfalls, rivers and lakes. Being an archipelago, the country's coastline would measure roughly 10,847 miles if laid end-to-end.Full Answer >
The most common theory about the name of the Black Sea is that, due to the inhospitable growth environment and lack of oxygen, the water appears dark. Other theories include shipwrecks and a Turkish homonym.Full Answer >
