Briefly describe some natural disasters.Search the Internet for information before coming to class
There are many kinds of natural disasters such as earthquake,flood,drought,forest fire,tsunami,snowstorm,blizzard,hailstorm,hurricane,typhoon,tornado,landslide,and volcanic eruption.
An earthquake is a sudden change or movement in the Earth's crust,causing a moving and shaking of the ground.A flood can be caused by excessive rainfall or quick melting of snow.When the water overflows a river's banks,the nearby low-lying land is flooded.When there is no rain for a long period of time,there is a drought:crops fail and people may die of thirst.A forest fire may be caused by lightning or human negligence -- for example,a burning cigarette butt -- or arson.It may destroy large forests.A tsunami is a giant wave that rolls onto the shore.It can be caused by an undersea earthquake,volcanic eruption or landslide.A snowstorm becomes a blizzard when the wind blows hard and visibility decreases.
