Chapter 11 Mountains The boundary between the continental crust and the oceanic crust “where the sea meets the land” Continental Margin
Continental Margins Passive Margin – Little to no tectonic activity Active Margin – Plate Tectonic activity present – subduction or collision
How do mountains form? From stress! There are 3 types: Compression Tension Shear
Folding of mountains - just like paper! Anticline - upfold Syncline - downfold
Faults - breaks and cracks. There are three types: Normal fault (one side of the boundary drops down) Reverse fault (one side of the boundary gets pushed up) Strike-slip fault (side by side, like san andreas)
Types of mountains Folded Dome Volcanic Fault block Collision boundary Gentle hill Volcanic Volcano! Fault block Due to compression, tension or shear stress
