Mountains

2. Definition of Mountain
A large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill.
5 types of mountains:
1. Fold Mountains (Folded Mountains)
2. Fault-block Mountains (Block Mountains)
3. Dome Mountains
4. Volcanic Mountains
5. Plateau Mountains

3. 1st type of mountains
Fold Mountains are formed by the buckling of the earth's crust.

4. 2nd Mountain Type
Fault-block mountains is a mountain formed by the combined processes of lifting, faulting, and tilting.

5. 3rd Mountain Type
Dome Mountains are the result of a great amount of melted rock pushing its way up under the earth.

6. 4th Mountain type
Volcanic Mountains is an opening in the earth's crust through which molten lava, ash, and gases.

7. 5th Mountain type
Plateau is an elevated, comparatively level expanse of land; a tableland.

8. How a Mountain formed?
A mountain is formed either by convergent or divergent.
Convergent means that the continental plates collide together to form mountains. An example is the Himalayan Mountains.
Divergent means that the continental plates move apart which makes lava push up to form a mountain. Such as Mt. Saint Helen.

9. Erosion
Mountains erode continuously. Erosion may be by water (rain or rivers), ice (glaciers) or wind.

10. Deposit
Mountains can deposit rocks, minerals and other sediments.

11. Constructive and Destructive Forces
Constructive forces affect the mountains by making it taller. Destructive forces can make the mountain smaller.

13. Mt. Saint Helens
Mt. Saint Helens was formed by a volcanic chain.

14. Himalayan Mountain
The Himalayas formed through million of years of earthquakes and the movement of the earth.

15. How does time affect landforms
Deposition and erosion can wear down a mountain range and make it smaller.

16. Facts and Information
Mountains usually have steep, sloping sides and sharp or slightly rounded ridges and peaks. A group of mountain ranges is called a mountain system. More than half of the world’s fresh water originates in mountains, and all the world's major rivers are fed from mountain sources.
