This presentation discusses different types of mountains. There are four main types: fold mountains, which are formed by the folding of tectonic plates; block mountains, which are formed by uplift due to faulting and have flat tops and steep sides; relict mountains, which are residual mountains formed by weathering processes that leave only resistant rocks; and volcanic mountains, which are formed when molten rock flows onto the surface through fissures caused by plate movement. Examples are given for each type, including the Himalayas for fold mountains, the Black Forest for block mountains, the Aravalli Ranges for relict mountains, and Mount Etna for volcanic mountains.

3. MOUNTAINS
THOSE LAND FORMS WHICH
HAVE A HEIGHTOF 900
METRES OR MORE ABOVE
SEA LEVEL ARE CALLED
MOUNTAINS.

4. TYPES OF MOUNTAINS
FOLD MOUNTAINS
BLOCK MOUNTAINS
RELICT MOUNTAINS
VOLCANIC MOUNTAINS

5. THE FOLD
MOUNTAINS
THEY ARE HEIGHER WHEN
COMPARED TO OTHER
MOUNTAINS.FOLDING OF THE
PLATES CAUSE FOLD
MOUNTAINS TO FORM.

6. THE BLOCK
MOUNTAINS
THE BLOCK MOUNTAINS
ARE FORMED AS A RESULT
OF UPLIFT OF LAND FORMS
DUE TO FAULTING.THESE
MOUNTAINS HAVE FLAT
TOPS AND STEEP SIDES.

7. THE RELICT
MOUNTAINS
DUE TO THE DIFFERENT WEATHERING
PROCESSES OF PROLONGED
DURATION,THE ROCKS THAT ARE NOT
VERY RESISTANT GET
DISINTEGRATED AND ONLY THOSE
RESISTANT PARTS REMAIN.THESE
MOUNTAINS ARE CALLED RESIDUAL
MOUNTAINS.

8. THE VOLCANIC
MOUNTAINS
VOLCANIC MOUNTAINS ARE
CAUSED WHEN MOLTEN ROCK
FLOWS OUT ON TO THE
EARTHS SURFACE THROUGH
FISSURES THAT ARE CAUSED
DUE TO THE MOVEMENT OF
PLATES

9. EXAMPLES OF MOUNTAINS
 FOLD MOUNTAINS --
THE HIMALAYA
THE ALPS
THE ANDES
THE ROCKIES

10. BLOCK MOUNTAINS
BLACK FOREST IN GERMANY
VOSAGES IN FRANCE

11. RELICT MOUNTAINS
THE ARAVALLI
RANGES
THE NILGIRIS IN
INDIA
