What do I write in my foldable?
Cause
Type of Boundary
Motion at Boundary
Effect
Land Feature Formed
Example
Convergent Boundaries
• Motion at Boundaries- Collision of Continental crust with continental crust.
• Land Feature Formed- Folded Mountains
• Actual Examples- Himalayas
Convergent Boundary – Indian and Eurasian Plates
Divergent Boundaries
• Motion at Boundary- moving away causing sea floor spreading.
• Land Features Formed- Midocean Ridges and Rift Valleys
• Examples- Mid-Atlantic Ridge and Iceland
Divergent Boundary – Arabian and African Plates
Transform Boundaries
• Motion at Boundary- sliding past each other (shearing)
• Land Feature Formed- Transform Fault
• Example- San Andres Fault
Convergent Boundaries and Subduction
• Motion at Boundary-
– Collision of Oceanic Crust/Oceanic Crust
• Land Feature formed- Volcanic Mountains, Island Arcs
• Example- Aleutian Islands
– Collision of Continental Crust and Oceanic Crust
• Land Feature formed- Trench, Volcanic Mountains
• Example- Andes Mountains
