Natural Disasters

       Have you ever turned on the news and heard about hurricane Katrina? If you have you probably saw a few pictures of peoples destroyed houses and knocked over trees. You have glimpsed only a little of the destruction of a natural disaster, in the next few paragraphs you will learn all about Natural Disasters.

Tsunamis

       Tsunamis are giant waves that can destroy millions of homes and even more lives in a matter of seconds. These giant waves are caused by underwater earthquakes or volcanoes. Tsunamis normally travel the entire ocean floor at about 60 to 120 miles per hour and can reach up to 800 kilometers in one sweep. More than one wave makes up a tsunami, there are about 10-30 minutes between waves the waves get bigger as they go on ( the second wave is bigger than the first one.)

Tornadoes

       Tornadoes also known as twisters or cyclones and are normally about one kilometer wide but leave great amounts of destruction behind them. Many tornado specialists follow tornados to try to understand them. This is important because we could learn the different signs of tornados.

Hurricanes

       Hurricanes normally happen in the two months of August and September. They can destroy millions of houses and even more lives. Have you ever heard of Hurricane Katrina? Well that’s just one of the many examples of hurricanes. Hurricanes travel at least around 31 miles per hour and can get up to 75 miles per hour.

Earthquakes

       You probably have heard about earthquakes before. They occur almost everyday so you don’t normally hear about them. Earthquakes are just what they sound like a shacking of the ground. This is caused by the friction holding a rock that is over come and blocks of rock slip against each other.

Volcanoes

       A volcano is a cone shaped mountain that has hot gases and molted rock inside. These hot gases and molted rock rise to the top of the volcano and erupt out of it.

Drought

       Drought is a period of time in which it dose not rain. They can last a year at a time where as a dry spell normally lasts 14 days. 

And all of these storms have become stronger Because of Global Warming.
