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

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

Transform Boundary – San Andreas 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
