Visual Summary
A study of the physical
geography of South Asia
will explain the contrasts
between the northern and
southern areas of the
region and how South
Asia’s large populations
depend upon the seasonal
monsoon rains that
sometimes bring
devastating consequences.
Section 1:
The Land
Places reflect the
relationship between
humans and the physical
environment. In South
Asia’s varied landscapes,
large numbers of people
depend on the region’s
physical environment, river
systems, and natural
resources for their
livelihoods.
Section 2: Climate and
Vegetation
The characteristics and
distribution of ecosystems
help people understand
environmental issues.
Seasonal winds in South Asia
strongly influence temperature
and rainfall, which affect what
crops people grow and how
people and the environment
are affected by too much or
too little rain.
The Land

systems, and natural
resources for their
livelihoods.

fertile soil to the floodplains, serve as
transportation routes, and provide
hydroelectricity.

Climate Regions
Much of South Asia has tropical climates
with ample rainfall and a variety of
vegetation; however, the climates vary
widely in the north and west, where
mountain ranges block rainfall.
• Tropical regions:
– Tropical wet
– Tropical dry

Seasonal Weather Patterns
Seasonal weather patterns bring muchneeded rainfall to South Asia, but monsoon
winds, as well as other natural disasters,
can also bring devastating hardships.
• Three distinct seasons:
– Hot
– Wet
– Cool
Comparing Climates
Seasonal Weather Patterns (cont.)
• These seasons depend on seasonal winds
called monsoons.
• Temperature and rainfall impact agriculture
in the region.
• Factors:
– Extreme heat
– Monsoon winds
Seasonal Weather Patterns (cont.)
• Natural disasters:
– Flooding from monsoon rains
– Cyclones
– Earthquakes
– Tsunamis
The monsoons are heaviest
in which part of South Asia?
A. Eastern
B. Western
C. Northern
D. Southern

summer and cold, dry air from inland
in winter

storm with heavy rains and high
winds which blow in a circular pattern
around an area of low atmospheric
