3. Those landforms which have a height of
900 metres or more above sea level are called
mountains.
4. Mountains have been divided
into four on the basis of their origin.
MOUNTAINS
Fold
Mountains
Block
Mountains
Relict
Mountains
Volcanic
Mountains
5. FOLD MOUNTAINS
Most of the mountains we see today are
fold mountains. They are higher when compared
to other mountains. Eg. Mt. Everest
6. Block mountains
The block mountains are formed as a
result of uplift by land forms due to faulting.
Eg: Black forest
7. Relict mountain
Due of the different weathering processes of prolonged
duration, the rocks that are not very resistant get disintegrated
and only those resistant part remain. These mountains are called
relict mountains. Eg: The Aravalli ranges and Nilgiris in India.
8. Volcanic mountains
Volcanic mountains are caused when molten rock
flows out onto the earth is surface through fissures that are
caused due to the movement of plates.
Eg: Mt. Fujiyama in Japan
