Natural HAzzards and dissasters

  1. 1. Landforms Inc. by Egan & Joshua 8b Start
  2. 2. <ul><li>This is our earth it is always changing in physical form through……. </li></ul>
  3. 3. volcanoes Tsunami Earthquakes To the end of the show
  4. 4. This is a volcano exploding…….
  5. 5. After it dries it becomes normal piece of land and rock
  6. 6. If it has a lava flow or have a couple of small eruptions it thikens
  7. 7. If its near water or the sea ……..

  15. 15. This Is What Happens When A Tsunami Strikes !!!!!!!!!! Lets see that again but closer
  16. 16. This is a diagram that shows what actually happens when a tsunami occurs when we look closely. The magma in the earths crust explodes then the lava erupts to the oceans surface then it creates powerful waves around it and those waves are called tsunami. Sometimes when a tsunami happens an earth quake happens
  17. 17. Another way that a tsunami can occur is by a large scale of earth quake that happens under the ocean. Then the power full cracks that occurs going up makes the tsunami high and powerful. Underneath is a demonstration of how it happens.
  18. 18. And that’s how a tsunami occurs Safety tips : 1.When a tsunami occurs stay calm 2.Try to save others too do not be selfish 3. Find a higher place that u can reach Act quickly Stay there This Is an Demonstration Back to home
  19. 19. Earth Quake Earth quake is a disaster that happens when the tectonic plates under land cracks. When the tectonic plates cracks this is what happens.
  20. 20. This is a simulation of what happens in a real earth quake
  21. 21. An earth quake happens usually when the tectonic plates move upwards, downwards, left or right. When an earth quake happens the land usually vibrates which causes buildings, houses, walls and roads to crumble. An earth quake is usually measured in seismometers . The machine that measures its scale is called the Richter scale.
  22. 22. So remember any time you are in an earth quake situation always find for safe shelter such as under the table, away from glass and under the door. What we meant by under the door is this position Back to home
  23. 23. Back to home
  24. 24. Back to home
