3. Introduction
Land forms are the natural
shapes or features called
landforms.
There are many different
types of landforms found
on the Earth.

4. A natural elevation of the
Earth’s surface having
considerable mass,
generally steep sides.

Mountain

5. Fold mountains are the most
common type of mountain. The
world’s largest mountain
ranges are fold mountains.
These ranges were formed
over millions of years.
Fold mountains are formed
when two plates collide head

6. Instead of the earth folding
over, the earth's crust
fractures (pulls apart). It
breaks up into blocks or
chunks. Sometimes these
blocks of rock move up and
down, as they move apart and
Block Mountains

7. Volcanic Mountains are formed
when molten rock (magma)
deep within the earth, erupts,
and piles upon the surface.
Magna is called lava when it
breaks through the earth's
crust. When the ash and lava
Volcanic Mountains

8. Plateau
Plateaus are raised areas
of land with a flatter top.
It differs from a mountain
in that a mountain has a
jagged peak at the top.
Plateaus form either when
mountains get worn down

9. Types of plateaus
• Intermontane Plateaus
• Piedmont Plateaus
• Continental Plateaus

10. Intermontane Plateau
Intermontane plateau that are
comparatively
Completely and partially
covered by the mountains

11. Piedmont Plateau
Piedmont plateaus that are
found at the foot of a range
of mountains

12. ContinentalPlateau
Continental plateaus means
when compared to
surrounding plains, some
plateaus are found to higher.

13. Plains
An extensive level, usually
treeless area of land on
Earth’s surface
Types of plains
• Structural Plains
• Alluvial Plains
• Glacial Plains

14. Structural Plains
Due to andogenic forces, an
area can be raised or
lowered. These actions are
called uplift and subsidence
respectively. These actions
cause plains to be formed.
They are called structural

15. Alluvial Plains
The plains which are formed
by the deposition of
sediments brought down by
the rivers from the high
altitudes are called alluvial
plains

16. Glacial Plains
Glacial plains which are
formed by the movement of
the glaciers under the
force of gravity .Such plain
are found in Canada,
Siberia, etc.

17. Coastal plains
• The plains are at the
coasts of the sea due to
the deposition work of the
sea waves.
