2
Stress – force that pushes or pulls rock Tension Compression Shearing Fault – Break in Earth’s crust where plate movement occurs Normal Reverse Strike-Slip
3
1. Divergent 2. Convergent 3. Transform
4
Movement – APART Type of Stress – Tension Type of Fault – Normal (hanging wall slips downward)
5
Landforms Continental/Continental: rift valley Oceanic/Oceanic: Mid-ocean ridge
6
Movement – TOGETHER Type of Stress – Compression Type of Fault – Reverse (Hanging wall moves over footwall)
7
Continental/Continental: Mountains (neither plate is more dense than the other, so subduction does not occur and the land is squeezed together into a mountain range) Oceanic/Oceanic or Oceanic/Continental: Deep ocean trench – oceanic crust is very dense, and leads to subduction
8
Movement – Slide past each other Type of Stress – Shearing Type of Fault –Strike-Slip (Rocks move sideways with little up or down motion) Landforms (Events) – EARTHQUAKE!!! (although earthquakes can occur at any plate boundary)
