(Homonym: boy).
Bright-colored; a float attached by rope to the seabed to mark channels in a harbor or underwater hazards.
Floating object used to mark channels for shipping or warn of hazards to navigation. Buoys come in different shapes, such as a pole (spar buoy), cylinder (automobile buoy), and cone (nun buoy). Light buoys carry a small tower surmounted by a flashing lantern, and bell buoys house a bell, which rings as the buoy moves up and down with the waves. Mooring buoys are heavy and have a ring on top to which a ship can be tied. + prikaži više

ETYM AS. waeter.
1. A clear colorless odorless tasteless liquid; SYN. H2O.
2. (Archaic) Once thought to be one of four elements composing the universe.
H2O liquid without color, taste, or odor. It is an oxide of hydrogen. Water begins to freeze at 0şC or 32şF, and to boil at 100şC or 212şF. When liquid, it is virtually incompressible; frozen, it expands by 1/11 of its volume. At 4şC/39.2şF, one cubic centimeter of water has a mass of one gram; this is its maximum density, forming the unit of specific gravity. It has the highest known specific heat, and acts as an efficient solvent, particularly when hot. Most of the world’s water is in the sea; less than 0.01% is fresh water.
Water covers 70% of the Earth's surface and occurs as standing (oceans, lakes) and running (rivers, streams) water, rain, and vapor and supports all forms of Earth's life.
Water makes up 60–70% of the human body or about 40 liters/42 quarts, of which 60% is inside the cells, 40% outside. A loss of 10% of this volume may cause hallucinations; a loss of 20%-25% may cause death. People cannot survive more than five or six days without water or two or three days in a hot environment. + prikaži više
