Mountainous and glacial landforms

  1. 1. - are those that rise higher than the rest of their surroundings. - exhibit slopes, summit areas and local reliefs. - they can be created by different tectonic activities.
  2. 2. • Are landforms that are controlled by geological processes that form them and continually act on them after their formation Anak Krakatau in Indonesia
  3. 3. • The volcano’s cone- shaped structure or edifice is carved out by the more or less symmetrical accumulation of lava and other pyroclastic materials around it’s central vent system
  4. 4. • are elevated portions of land that are formed by geologic activities such as faulting • usually covered with grass and are used as grazing lands for goats, cattle and carabaos • Smaller than mountainsChocolate Hills in Bohol
  5. 5. • During dry season, the green grasses covering the hills turn brown making the landforms appear like thousands of chocolate hills The Painted Hills in US
  6. 6. • Also called as Dale is a low area between hills, often with a river running through it. • Shapes of Valleys – V-shaped Valley – U-shaped Valley Ifugao Valley
  7. 7. • A valley formed by flowing water, or river valley, is usually V-shaped. The exact shape will depend on the characteristics of the stream flowing through it.
  8. 8. • A tunnel valley is a large, long, U-shaped valley originally cut under the glacial ice near the margin of continental ice sheets such as that now covering
  9. 9. - results of the actions of the glaciers. - are huge slow-moving bodies of ice. - created by the movement of large ice sheets during the Quaternary Glaciations - Two types of Glaciers: 1. Alpine 2. Continental
  10. 10. • Continental Glaciers are formed in cold polar regions
  11. 11. • Alpine Glaciers are formed in high mountains
  12. 12. • Also known as table lands or flap-topped mountains • Are portions of land elevated thousands of feet above surroundings • They are the results of geologic uplifts or the slow movement of large parts of stable areas of Earth’s crust
  13. 13. • Causes of formations of Plateaus –Volcanic Eruptions –Weathering
  14. 14. • covers about 45% of Earth’s land surface • low plateaus are often used for farming • high plateaus are suitable for livestock grazing Tibetan Plateau
