It includes the states of: Texas, Oklahoma, Kansas, Nebraska, and South Dakota </p> <p>How and why do they occur?</p> <p>The middle states are located between the warm air of the Gulf of Mexico and the cold air of the Pacific Ocean from Canada.</p> <p>Tornados vs. Hurricanes</p> <p>TornadoHurricanes</p> <p>Geological Disasters</p> <p>Natural disasters of the land</p> <p>Earthquake?</p> <p>Whats that??</p> <p>EarthquakesA sudden shaking of the ground as a result of movements of the earths tectonic plates </p> <p>How do they happen?The earths surface rests on moving sheets of crust called tectonic platesThese plates move VERY slowly </p> <p>How do they happen?When the plates collide, they create mountainsWhen the plates separate, they form volcanoes.</p> <p>Hydrological DisastersNatural disasters of the water</p> <p>Types of Meteorological Disasters</p> <p>Tsunami.A long, high sea wave caused by an earthquake or other disturbance.Floods.An overflow of water beyond its normal limits, especially over what is normally dry.</p> <p>How do They Occur</p> <p>TSUNAMI</p> <p>FLOODS</p> <p>Where do Tsunami Occur</p> <p>Where do Floods occur</p> <p>Lets see what they can do.</p> <p>video</p> <p>StatisticsIn 2012, there were 905 natural catastrophes worldwide. 93% of which were weather-related disasters. 45% were meteorological (storms)36% were hydrological (floods)12% were climatological (heat waves, cold waves, droughts, wildfires)7 % were geophysical events (earthquakes and volcanic eruptions).
