Notes
  • It's not a bad presentation but the first few slides are not clear enough.
    The rest of the slides look good enough .
    I think there should have been a bit more clear description for the understanding purpose of common people.

    • Earth has 12 tectonic plates
    • They have lots of force
    • Forces are examples for stress

    • Shearing is also a type of stress
    • Shearing has the power to cause masses of rock to slip
  • 7. Types of Faults
    • One type of fault is a normal fault
  • 8. Reverse fault
    • There is one type of force it is a reverse fault
    • It makes the hanging wall move up relative to the footwall
  • 9. Strike-slip fault
    • There is a fault called strike-slip fault
    • Strike slip fault go past each other
  • 10. Anticline, Syncline, and Plateau
    • A anticline is an upward fold formed by compression
    • Syncline is a downward fold in a rock
    • Plateau is a large area of flat land high above above sea level
