INDUS
DELTA
Ms Behjat Jami
50
INDUS DELTA
A delta is formed at river mouth
due to sedimentation process
done by the river
 Sand and silt which come with
the river water settle in the sea
bed; slowly a small island
comes out of the surface of the
sea is called Delta

Desert

Physical Features
Sandy, stony & rocky
 Water is scarce
 Land is fertile but needs water
to show its strength
 Natural vegetation is scattered
with bushes, small trees &
thorny plants

Ms Behjat Jami
63
Desert

Physical Features
Sand dunes are special feature
of a desert
 Sand dunes are formed due to
high wind activities
 Air takes layers of sand from
one place to another place
 Most of the dunes in Thar
desert are longitudinal

Desert
Desertification:
Desertification is a natural
process in which a desert
covers more area due to
climatic changes
 Reclamation:
Reclamation is to turn
deserted area into arable
land by human efforts


PLATEAUS
Ms Behjat Jami
68
PLATEAUS
a plateau is a high flat land
little higher than normal level
of land
 Pakistan has two plateaus:
Potwar Plateau
(North West Punjab)
Balochistan Plateau
(central Balochistan)

Ms Behjat Jami
