This document discusses different types of natural disasters including meteorological, geological, and hydrological disasters. Meteorological disasters include tropical storms like hurricanes, typhoons, and cyclones which form over oceans in different regions. Tornadoes form over land in Tornado Alley in the central US. Geological disasters include earthquakes, which occur along fault lines as tectonic plates collide or separate. Hydrological disasters involve water and include mudslides, rockslides, and avalanches caused by pressure building on external surfaces.
Natural disasters
- 2. What is a Natural Disaster? A natural disaster is an event caused by natural forces of nature that has a large effect on the human population.
- 3. Meteorological Natural disasters of the atmosphere
- 4. Cyclone, Typhoon, Tornado, Hurricane Whats the difference??
- 5. Cyclone, Typhoon, Hurricane Define: A tropical storm that forms over an ocean The difference is WHERE they form Cyclone: Asia, South of the Equator Typhoon: Asia, North of the Equator Hurricane: Atlantic Ocean & East Coast of North America
- 7. Test Your Knowledge Write these down: What wind storm occurs in these countries: United States: Australia: India: Japan: Canada:
- 8. Cyclone, Typhoon, Hurricane (Video) Characteristics: Hard rain, flooding, high winds Duration: 8 24 hours of full force Where: East Coast, USA
- 10. East Coast, USA
- 11. Lets see what they can do
- 12. Wait, whats a Tornado?? Isnt that the same??
- 13. Tornado A Tornado forms over land. Also called a Twister Occurs in Tornado Alley in the USA
- 14. Tornado Alley Tornado Alley is the area where Tornados form the most. It includes the states of: Texas, Oklahoma, Kansas, Nebraska, and South Dakota
- 15. Tornado Alley How and why do they occur? (Video) The middle states are located between the warm air of the Gulf of Mexico and the cold air of the Pacific Ocean from Canada.
- 17. Lets see what they can do
- 19. Geological Disasters Natural disasters of the land
- 21. Earthquakes A sudden shaking of the ground as a result of movements of the earths tectonic plates
- 22. How do they happen? The earths surface rests on moving sheets of crust called tectonic plates These plates move VERY slowly
- 23. How do they happen? When the plates collide, they create mountains When the plates separate, they form volcanoes
- 24. 際際滷s 3 Types: Mudslide (Mud), Rockslide (Rocks), Avalanche (Snow) Characteristics: Accelerating materials in large amounts Cause: Pressure on the external surface
- 25. Hydrological Disasters Natural disasters of the water
