Plate Boundaries of Earth’s Land Features By: Stacy Vinson

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 Indian Plate

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 Arabian Plate Red Sea African Plate

Transform Boundaries Motion at Boundary- sliding past each other (shearing) Land Feature Formed- Transform Fault Example- San Andres Fault

Transform Boundary – San Andreas Fault www.geology.com

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

Convergent Boundary – Oceanic & Oceanic Note – plates are reversed http://pubs.usgs.gov/gip/dynamic/understanding.html & http://www.geology.com
