3. Natural disasters are tremendous forces of nature that have been known to destroy cities and towns all over the world.

4. Some of the most well-known natural disasters that have happened every year are volcanoes and earthquakes.

9. Volcanoes
What are volcanoes? Please click on the image to watch the video before moving on

10. Volcanoes are mountains, but they are different from other mountains.
They are built by accumulation of their own eruptive products.

11. A Volcano Defined
A volcano is a land form where molten rock erupts through the surface of the planet. Gases and rock shoot up through and spill over with lava fragments.

12. Trophy time! What is a volcano?
A land form where molten rock erupts through the surface of the planet.
A sudden shaking of the earth.
A vast tropical storm that has winds whipping around.

13. You Did Great!

14. Sorry, a sudden shaking of the earth is an earthquake
Let’s try again!

15. Sorry, a vast tropical storm that has winds whipping around is a hurricane .
Now ,Let’s Try again.

16. The word "volcano" comes from the little island of Vulcano in the Mediterranean Sea off Sicily.

17. A volcano as seen by the eyes of a child

18. Types of volcanoes
Volcanologists have classified volcanoes into groups based on the shape of the volcano, the materials they are built of, and the way the volcano erupts.
volcanic material: lava, rock fragment, and gas

19. Volcano Groups Composite Volcanoes
Shield Volcanoes (also called shields)
Cinder Cones
Spatter Cones
Complex Volcanoes (also called compound)

20. Ready to get your trophy?
Volcanoes are a mountain which accumulated by
Folding and crumpling.
Uplift and Erosion. 
Accumulation of their own eruptive products

21. You Did Great!

22. Let’s try again!

25. Please try again!

26. Positive Products from Volcanoes
Geothermal Energy Volcanic ash

27. Ash blows over land and increases soil fertility for forests and agriculture by adding nutrients and acting as a mulch.
Groundwater heated by large, still hot magma bodies can be tapped for geothermal energy.

28. Trophy time! Positive Products from Volcanoes are Geothermal Energy
Power point
An earthquake

29. Trophy for you!! You did great!

30. Please let’s try again.

31. Earthquake Please watch this vedio !

32. An Earthquake
A trembling or shaking of the ground caused by the sudden release of energy stored in the rocks below the surface, radiating from a fault along which movement has just taken place.

33. Measuring an Earthquake
The Richter scale 1-10

34. Facts about Earthquakes
 Earthquakes can occur at any time of the year and at any time of the day or night.
Earthquakes occur under all weather conditions, sunny, wet, hot, or cold--without special tendency.

35. Trophy time! What is an earthquake?
A land form where molten rock erupts through the surface of the planet.
Shaking of the ground caused by the sudden release of energy stored in the rocks below the surface.
A vast tropical storm that has winds whipping around.

36. You Did Great!

37. Sorry, a land form where molten rock erupts through the surface of the planet is a volcano..

38. Sorry, a vast tropical storm that has winds whipping around is a hurricane.

39. Myths about Earthquakes
The ground does not open up and swallow people (a commonly feared myth). Open ground cracks may form during an earthquake--related, for example, to land sliding or ground slumping. But such fissures are open gaps (they don't "swallow") that a person could stand in.

40. Trophy Time
What scale is used to measure an earthquake? Pedometer Richter scale Mechanical scale

41. Trophy for you!! You did great!

42. Lets' try again.

43. Wrap Up
Good job!
Review: earthquakes and volcanoes are natural disasters.
A volcano is a land form where molten rock erupts through the surface of the planet. Gases and rock shoot up through and spill over with lava fragments.
Earthquakes and volcanoes occur in the Ring of Fire.
