arthquakee


An earthquake, earthquake or earthquake also called (from the Greek "σεισμός" tremor) or earthquake is ground shaking produced by the collision of tectonic plates and the energy release during a sudden reorganization of materials Earth's crust to overcome the state of mechanical equilibrium. 






acid rain


Acid rain is formed when moisture in the air combines with nitrogen oxides and sulfurdioxide emitted by factories, power plants and vehicles that burn coal or petroleum products. In interaction with water vapor, these gases form sulfuric and nitric acids. Finally, these chemicals fall to the ground accompanying precipitation, forming acid rain.

tornado


A tornado is a meteorological phenomenon which is a rotating column of air violently, itslower end is in contact with the Earth's surface and top with a cumulonimbus cloud or, exceptionally, with the base of cumulus cloud. 1 This is the most intense weather phenomenon known. tornado








hail


Hail is a type of precipitation that consists of irregular particles of ice. Hail occurs in severe storms that occur in the supercooled water droplets, ie but still liquid at temperatures below its normal freezing point (0 ° C), and occurs in both summer and winter, although the case isthis more when the dog days, days of the year in which the heat is stronger.
