- 1. This type of earthquake wave can travel the fastest of the three and can pass through solids.
- 4. This is a layer of solid,unbroken rock.It marks the dividing line between soil and rock.
- 5. The process of materials being laid down or deposited by wind, water and ice.
- 11. refers to the mechanical and chemical processes that break down rocks by means of water, glacial ice, wind and waves
- 13. The distance between two major earthquake waves
- 15. What is the name of the 8 major “plates”
- 16. This is the third layer of soil, it contains pieces of larger rock and clay and is usually light coloured
- 18. Constantly circulating, the same thing happens in the mantle
- 19. This type of volcano has large amounts of gas trapped inside it, this makes the eruptions violent. This type of volcano is only active for a short period of time before it becomes dormant.
- 20. This type of weathering is caused by the activity of living things VolcanoStructure what does a ash cloud, magma chamber, central vent, side vent, lava, old layers of lava and the earth's crust make up?
- 26. this type of Earthquake wave has a rolling motion. They cause the most damage out of the three waves. San Andres What is the name of a famous fault line?
- 28. The name of the thing when two plates collide and cause a crack
- 30. scale What machine is used to measure the magnitude of an earthquake?
- 31. What are the name of scientists who study earthquakes?
- 32. This type of weathering happens when chemicals in the air mix with moisture in the air and creates a weak acid that can wear away at things.
- 33. where the earthquake begins below the surface
- 35. Sudden release of stress between rocks that causes a shaking in the ground
- 36. The science of living organisms and things
- 38. Molten mass of of mostly iron, towards the center of the earth
Down
- 2. Hill or mountain that has a vent in which lava and rock fragments erupt from the earth's crust
- 3. Gasses join together with moisture in the air or mix with rain and form acids that return to earth
- 6. This type of volcano has very mild eruptions that can occur several times. The magma inside of this volcano is rich in iron and magnesium. His volcano has a gentle slope.
- 7. The name of what once was a supercontinent
- 8. Thin layer of solid rock
- 9. What type of volcano is combined of a cinder cone and a shield volcano?
- 10. This happens when two plates collide and one of the plates get pushed under the other
- 12. solid portion of something
- 14. Occurs when a rock is broken down by by physical forces, such as wind or water. A form of this type of weathering is frost wedging
- 17. Large ball of iron and nickel, is almost as hot as the earth's surface
- 21. The magma inside of this volcano is rich in silica. The eruption from this volcano can be explosive or flowing lava. This is the most deadly type of volcano.
- 22. This type of earthquake waves travel slower than P waves and can only pass through solids.
- 23. What is the fastest moving wave in a earthquake?
- 24. this is the second layer of soil, it is rich in nutrients needed for plant growth
- 25. This is below the earth's crust. It is hot and thick
- 27. The name of the machine used to measure the intensity of an earthquake
- 29. This is the name of the center of a earthquake
- 34. This type of soil is the top layer of soil, it keeps the ground damp by preventing to much water from evaporating
- 37. occurs when the products of weathering are transported from place to place
