1. LESSON 3 MOUNTAINS

2. TYPES OF MOUNTAINS 1. FOLDED MOUNTAINS 2. FAULT-BLOCK MOUNTAINS 3. VOLCANIC MOUNTAINS 4. RESIDUAL MOUNTAINS

3. Most common type of mountain When layers of rock compress or converge and push upward, produce a protruding piece of land that becomes a folded mountain. OROGENESIS is the thrusting and folding of the continental crust that forms a mountain range. 1. FOLDED MOUNTAINS

4. EXAMPLE OF folded MOUNTAIN

7. HIMALAYAS IN ASIA

8. Two types of fold ANTICLINES SYNCLINES ANTICLINES – (upward folds) is a type of fold that is an arch-like shape. SYNCLINES – (downward folds) is the inverse of an anticline

9. ANTICLINES SYNCLINES

10. Fault-block mountains are formed by fractures on earth’s crust which break up into several blocks or chunks. A fault divides a piece of land into two separate blocks. Heat and pressure caused by plate movement can lift one block and pull down the other to form a mountain. As one block elevates and the other sinks, a depression forms between them. Erosion from elevated portion will fill up this depression and gradually create a slope that evolves into a fault-block mountain. 2. FAULT-BLOCK MOUNTAINS

15. Volcanic mountains or volcanoes are mountains which can spew lava on the surface earth They are formed from the materials arising from the interior of the earth and accumulating on the surface. Volcanic mountains usually start out as a simple crack on the crust that extends deep into the inner layers of the earth; this fissure in the ground is called a volcanic vent . 3. VOLCANIC MOUNTAINS

16. EXAMPLE OF volcanic MOUNTAIN

17. MOUNT MAYON

18. MOUNT PINATUBO

19. Residual mountains are formed by the erosion of debris from an elevated area. This erosion occurs through the process known as denudation. DENUDATION is a process in which the parts of an elevated portion of land wear away and form another landform on the surface. 4. RESIDUAL MOUNTAINS

23. Major mountain range are: 1. ANDES MOUNTAIN RANGE 2. THE NORTH AMERICAN CORDILLERA 3. THE APPALACHIAN RANGE

24. 1. ANDES MOUNTAIN RANGE The ANDES is the longest mountain range in the world, extending 7000 km along western coast of South America and intersecting parts of Colombia , Peru, Chile, Venezuela, Bolivia, and Argentina. The highest peak of Andes mountain range is MOUNT ACONCAGUA which rises up to 6962 m above sea level.

25. 2. THE NORTH AMERICAN CORDILLERA The North American Cordillera runs a distance of about 6400 km along Western North America, and is 6168 m above sea level. 3. THE APPALACHIAN RANGE The APPALACHIAN RANGE stretches along the eastern side of North America for 3200 km. Its highest peak is located on Mount Mitchell , which is 2037 m above sea level.

26. The Longest Mountain Range in t he Philippines is the SIERRA MADRE , which strecches for 680 km from the Province of Cagayan in the north to Quezon in the south. The highest peak in the country is MOUNT APO , located between the Provinces of Davao and Cotabato in Mindanao. It has an elevation of 2954 above sea level.

27. The Alpine- H imalayan Belt extends from the Atlantic region of northern Africa to the far eastern side of Sumatra, Indonesia, intersecting the Alps mountains and the Himalayas among other mountain ranges. ALP MOUNTAINS encompasses the south central region of Euope , reaching 1126 km along the southern coast of France to the coastlines of Albania in southern Europe. The highest peak of the range is MOUNT BLANC , which rises to a height of 4807 m HIMALAYAS , runs for 2414 km along the southern region of Asia, tracing the boundary between the Indian sub-continental plate and the Tibetan plateau, which stretches across regions of Central and East Asia. MOUNT EVEREST , the highest mountain in the world, is a segment of the Himalayas located on the boundary separating Nepal and Tibet. The highest point of MOUNTAIN EVEREST rises to a Height of 8848 sea level. ALPINE HIMALAYAN BELT
