Sarah And Shontell Folder4

  1. 1. By Shontell Roberts and Sarah Keith Core 1,Science Earthquakes For Kidz
  2. 2. Stress <ul><li>There are three different kinds of stress can occur in the crust- tension, compression, and shearing. </li></ul><ul><li>These forces cause some rocks to become brittle and snap. </li></ul><ul><li>Other rocks bend slowly like road tar softened by the sun. </li></ul>
  3. 3. Compression <ul><li>The stress force called compression squeezes rock until it folds or breaks </li></ul><ul><li>One plate pushing against another can compress rock like a giant trash contractor. </li></ul>
  4. 4. Tension <ul><li>The stress force called tension pulls on the crust, stretching, rocks so that it becomes thinner in the middle </li></ul><ul><li>The effect of tension on rock is somewhat like pulling apart a piece of warm bubblegum. </li></ul>
  5. 5. Shearing <ul><li>Stress that pushes a mass or rock in to opposite direction is called shearing </li></ul><ul><li>Shearing can cause rock to break and slip apart or to change its shape. </li></ul>
  6. 6. Reverse Faults <ul><li>Reverse faults are in places where the rock of the crust is pushed together compression cause’s reverse faults to form </li></ul><ul><li>A reverse fault has the same structure as a normal fault, but the blocks move in the opposite direction. </li></ul>
  7. 7. Strike-Strip Fault <ul><li>In places where plates move past each other shearing creates strike-slip faults </li></ul><ul><li>In a strike-strip fault other rocks on either side of the fault slip past each other sideways with little up or down motion. </li></ul>
  8. 8. Normal Faults <ul><li>Is when tension in the crust pulls the rock apart causing normal faults </li></ul><ul><li>Normal faults have a footwall and a hangwall most faults occur along boundaries. </li></ul>
  9. 9. Hang wall <ul><li>The hang wall is the block of rock that lies below the footwall like a fault </li></ul><ul><li>A hang wall happens when they move away from each other </li></ul>
  10. 10. Anticline <ul><li>A fold in rock that bends upward into an arch. </li></ul><ul><li>Like going up a mountain. </li></ul>
  11. 11. Footwall <ul><li>When movement occurs the normal fault move downwards . </li></ul><ul><li>This happens when two pieces of earths crust are under tension. </li></ul>
  12. 12. Syncline <ul><li>A fold in rock that bends down to form a valley. </li></ul><ul><li>Like going down a hill or valley. </li></ul>
  13. 13. Plateau <ul><li>Plateau is a large area of flat land elevated high above sea level. </li></ul><ul><li>Flat land with mostly grass and few trees. </li></ul>
