Mountainous and glacial landforms

2. - 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.

3. • Are landforms that
are controlled by
geological processes
that form them and
continually act on
them after their
formation
Anak Krakatau in Indonesia

4. • 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

5. • 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

6. • 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

7. • 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

8. • 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.

9. • 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

10. - 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

11. • Continental
Glaciers are
formed in cold
polar regions

12. • Alpine
Glaciers are
formed in high
mountains

13. • 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

14. • Causes of
formations of
Plateaus
–Volcanic
Eruptions
–Weathering

15. • covers about 45% of
Earth’s land surface
• low plateaus are often
used for farming
• high plateaus are
suitable for livestock
grazing
