NATURAL DISASTERS

TORNADO

TORNADOA tornado is a violently rotating

column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones,[1] although the word cyclone is used in meteorology, in a wider sense, to name any closed low pressure circulation. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust.

LIGHTNING

LIGHTNING Lightning is a massive 

electrostatic discharge between electrically charged regions within clouds, or between a cloud and the Earth's surface. The charged regions within the atmosphere temporarily equalize themselves through a lightning flash, commonly referred to as a strike if it hits an object on the ground. There are three primary types; from a cloud to itself (intra-cloud or IC); from one cloud to another cloud (CC) and finally between a cloud and the ground (CG). Although lightning is always accompanied by the sound of thunder, distant lightning may be seen but be too far away for the thunder to be heard.

EARTH QUAKE

EARTH QUAKE An earthquake (also known as

a quake, tremor or temblor) is the result of a sudden release of energy in the Earth'scrust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter scale

TYPES OF EARTH QUAKE

CYCLONE

CYCLONE In meteorology, a cyclone is an area of

closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate anti-clockwise in theNorthern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. According to NHC glossary, warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within synoptic scale. Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale

TSUNAMI

TSUNAMI A tsunami (plural: tsunamis or tsunami; from 

Japanese:  津波 , lit. "harbour wave"; English pronunciation: /suːˈnɑːmi/ soo-NAH-mee or /tsuːˈnɑːmi/ tsoo-NAH-mee) is a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions(including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.

VIRUS A virus is a small infectious agent that

replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from

 animals and plants to bacteria and archaea.[1]

FACTORY WASTE

FACTORY waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, mills and mines. It has existed since the outset of the industrial revolution.

BACTERIABacteria (i/bækˈtɪəriə/; singular: bacterium)

constitutealarge domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals.

CRIME

In ordinary language, the term crime denotes an unlawful act punishable by a state.[1] The term crime does not, in moderncriminal law, have any simple and universally accepted definition,[2] though statutory definitions have been provided for certain purposes.
