Earthquakes

3. Is a water wave triggered by an earthquake, volcanic eruption, or landslide. Larger the natural disaster, the larger the _______.
5. A process in which an earthquake causes shaking of the ground that causes soil to act like a liquid. For a short time the soil becomes like a thick soup. Only occurs in area of loose sand with large amounts of water.
8. Is a smaller earthquake that follows a more powerful earthquake in the same area. This can sometimes cause more damage than the original earthquake because the damage from the original earthquake weakened buildings.
10. Is a shaking of the ground caused by the sudden movement of large blocks of rock along a fault. A sudden release of stress is what causes_______.
12. Is the force exerted when an object presses on, pulls on, or pushes against another object.
13. fault Blocks of rocks move sideways on either side of the fault plane. Stresses that push blocks of rock HORIZONTALLY cause earthquakes.
14. Caused by continental-continental collision or Oceanic-continental subduction, which is caused by tension from convergent boundaries. Most mountains occur in ranges or belts.
15. Is a mountain that forms as continental crust crumples and bends into folds. These mountains form as a oceanic plate sinks under the edge of a continent or as continents collide.

1. the block of rock above the fault plane slides down relative to the other block. Stress that PULLS rocks apart.
2. Although mountains are growing in height, mountains are also being eroded away. Erosion is caused by water, wind, and ice. Young mountains are rugged while old mountains are rounded, erosion is a huge factor for this.
4. Is a section of a fault with few earthquakes compared with sections of the fault on either side of the gap. In this gap is where stress is building up and scientists can predict that there will be an earthquake eventually.
6. A fracture, or break, in Earth’s lithosphere, along which blocks of rock move past each other.
7. Mountains that form as blocks of rock move up or down along normal faults. They form when the lithosphere is stretched and pulled apart. When the rocks are pulled apart the rocks on both sides of the fault become bunched together creating mountains.
9. the block of rock above the fault plane moves up relative to the other block. Stress that pushes rock TOGETHER.
11. Moment scale is used to scale the total amounts of energy released by earthquakes.Richter scale is a more commonly used scale.
