Suggested activity:Ask students -1. Why are compressional forces only felt at convergent plate boundaries? At convergent plate boundaries, the direction of movement of convection currents cause plates to move towards each other.

+ 2 Lesson Outcomes By the end of the lesson, we will be able to describe the characteristics of fold mountains describe the characteristics of landforms and phenomena associated with converging continental and oceanic plate boundaries
+ 9 Fold Mountains Folding When compressional force creates immense pressure which causes the layers of rocks to buckle and fold Anticline (Upfold) Syncline (Downfold) Fracture Formed when increasing compressional force on one limb of a fold causes rocks to buckle Limb moves forward to ride over the other limbarmanalluwie.blogspot.com
