+ Elective Geog (New) Secondary 3 E Week 6: Living with Tectonic Hazards armanalluwie.blogspot.com
+ 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
+ 4 Fold Mountains Formed when layers of rocks are compressed and folded Young – less than 100 million years old Old- 270- 400 million yearsarmanalluwie.blogspot.com
+ 7 Fold Mountains Formed when layers of rocks are compressed and folded Found at Convergent plate boundaries Common in sedimentary rocksarmanalluwie.blogspot.com

+ 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
+ Distribution of Fold Mountains
+ 13 Converging: Continental- Continental Fold Mountain Range
+ 16 Converging: Oceanic- Continental Continental Plate Fold Mountains buckles and folds On Continental Plate Oceanic Trench Magma rises through At Subduction Zone crusts giving rise to Volcanoes Denser Oceanic Plate Solid mantle material subducts beneath the less melts and forms magma dense Continental Platearmanalluwie.blogspot.com
+ Converging: Oceanic- Continental Fold Mountains/ Volcanoes Sunda Oceanic Trench
+ TRANSFORM PLATE BOUNDARY - Plates slide past each other - A fault line is created * Transform plate boundaries are also known as ‘conservative’ plate boundaries
+ LET’S WRECK IT!
+ TRANSFORM PLATE BOUNDARY - The movement results in the formation of a fault - In the process, tremendous stress builds up and is eventually released, often in the forms of tremor and earthquakes
+ ISTANBUL TURKEY
E.g. North Anatolian Fault, Turkey How would the plate movement affect the two cities shown in time to come?
