South Asia boasts the world’s tallest
mountains. Within India, Nepal, Pakistan,
and Kashmir are 24 mountains that soar
above 25,000 feet (7,620 m) high. Of all
the continents, Asia alone has mountains
of this height.
A Separate Land
Most of South Asia forms a peninsula
surrounded by the Arabian Sea, the Bay
of Bengal, and the Indian Ocean and is
cut off from the rest of Asia by mountains.
South Asia also includes Sri Lanka and
other smaller islands.
(page 569)
A Separate Land (cont.)
How might South Asia’s mountains
have helped shape the region’s
history?
Mountains physically limited contact
with the rest of Asia; however, mountain
passes allowed invaders and traders to
enter the subcontinent.

A Land of Great Variety
• The Himalaya Scientists believe that
about 60 million years ago, the Indian
subcontinent was part of the same
large landmass as Africa. 
• After breaking away, the subcontinent
drifted and smashed into the southern
edge of Asia. 
• The collision’s force created the
Himalaya, the ranges that contain
the world’s highest mountains.
(pages 570–571)

A Land of Great Variety (cont.)
• Other Northern Landforms The
Himalaya, the Karakoram, and the
Hindu Kush form a mountainous barrier
between the subcontinent and the
rest of Asia. 
• Invaders, however, used crossing
places, such as the Khyber Pass,
to enter the region. 
• At the foot of the Himalaya lies the fertile
Ganges Plain, home to one-tenth of the
world’s population.
(pages 570–571)
Click the mouse button or press the
Space Bar to display the information.
A Land of Great Variety (cont.)
• Three rivers–the Indus, the Ganges,
and the Brahmaputra–water the plain. 
• Central Landforms The Vindhya
Range divides India into northern and
southern regions, each of which
developed a distinct culture.
(pages 570–571)
Click the mouse button or press the

A Land of Great Variety (cont.)
• Southern Landforms 
- In southern India, two chains of eroded
mountains–the Eastern and Western Ghats–
form a triangle that holds the Deccan
Plateau. 
- The mountains’ blocking of rainy winds keeps
the plateau arid. 
- At India’s southern tip, the lush Karnataka
Plateau receives plenty of precipitation. 
- Maldives and Sri Lanka are island countries
south of India.
(pages 570–571)

Major River Systems
• Indus and Brahmaputra Rivers 
- The Indus River, which flows through
Pakistan to the Arabian Sea, serves as an
important waterway and water source. 
- The Indus River valley was the cradle of
ancient India, one of the world’s earliest
civilizations. 
- The Brahmaputra River flows east through
the Himalaya and then west into India and
Bangladesh, where it meets the Ganges
River. 
- The two rivers form a delta before emptying
into the Bay of Bengal.

Major River Systems (cont.)
- The Brahmaputra is a major inland waterway
and provides Bangladesh with hydroelectric
power.
(page 572)
Major River Systems (cont.)
• Ganges River 
- The Ganges, South Asia’s most important
river, is fed year-round by water from the
Himalaya. 
- Therefore, it retains its size even during the
dry season. 
- During the rainy season, however, it often
floods its banks. 
- Hindus consider the river’s waters to be
sacred. 
- The Ganges River flows through the Ganges
Plain, India’s most agriculturally productive
area and the world’s largest alluvial plain.

Asia would you
expect to be most
agriculturally
productive? Why?
Click the mouse button or press the
Space Bar to display the answer.
Analyzing Maps
The Ganges Plain,
Bangladesh, the
area between rivers
in northern
Pakistan, and Sri
Lanka would be
most agriculturally
productive because
of the presence
of rivers, alluvial
soil, climate
favorable to
agriculture, and
the absence of
landforms that block
rain.

Throughout the 1990s, India was shaken
by frequent major earthquakes. In 1993,
an earthquake in Maharashtra in southern
India killed over 9,000 people, according
to figures released by the Indian
government. Some people believe the
death toll may have been as high as
30,000. In January 2001, nearly 20,000
Indians were killed in another devastating
earthquake.
South Asia’s Climates
Although much of the subcontinent lies
south of the Tropic of Cancer and has a
tropical climate, the climates of the
northern and western parts of the region
vary widely from highlands to deserts.
(pages 575–577)
South Asia’s Climates (cont.)
• Tropical and Subtropical Climates 
- The west coast of India, the Ganges Delta,
and southern Sri Lanka have tropical rain
forest climates. 
- The rain forests absorb much of the heavy
annual rainfall. 
- The central Indian steppe and eastern Sri
Lanka have a tropical savanna climate, with
wet and dry seasons, grasslands, and
deciduous forests. 
- A humid subtropical climate extends across
Nepal, Bhutan, Bangladesh, and
northeastern India.
(pages 575–577)
Click the mouse button or press the
Space Bar to display the information.
South Asia’s Climates (cont.)
• Highlands Climates Snow never melts
in the Himalayan highlands. 
• On the lower slopes, the climate is
temperate enough to support deciduous
and coniferous forests. 
• The foothills support grasslands and
stands of bamboo.
(pages 575–577)
Click the mouse button or press the
Space Bar to display the information.
South Asia’s Climates (cont.)
• Dry Climates Dry climates, which occur
along the lower Indus River, produce the
Great Indian Desert and the surrounding
steppes. 
• Dry deciduous forests cover vast
stretches of India’s interior.
(pages 575–577)
Click the mouse button or press the
Space Bar to display the information.
South Asia’s Climates (cont.)
In which areas do you think most of the
region’s people live? Why do you think
so?
They probably live in the tropical and
subtropical areas, where there is
abundant rainfall. The highlands are too
cold and rugged to support substantial
human settlement, nor can the arid
areas support large human populations.
(pages 575–577)
Click the mouse button or press the
Space Bar to display the answer.
Monsoons
South Asia’s three seasons–hot, cool, and
wet–depend on the seasonal monsoons
that blow from the north and northeast to
produce the cool, dry season and from the
south and southwest to produce the rainy
season.
(pages 577–579)
Monsoons (cont.)
• Monsoon Rains Monsoon rains are
heaviest in eastern South Asia. 
• When the rains sweep over the GangesBrahmaputra delta, the Himalaya block
them from moving north. 
• As a result, the rains move west to the
Ganges Plain, bringing needed rainfall
for crops.
(pages 577–579)
Click the mouse button or press the
Space Bar to display the information.
Monsoons (cont.)
• Natural Disasters Both the high
temperatures of the hot season and the
heavy rains of the wet season have
positive and negative effects. 
• Extremely high temperatures and lack
of rain can dry out the soil, causing
drought. 
• Too much rain caused by monsoons
brings floods and results in great
damage to land and property, as well
as loss of human life.
(pages 577–579)
Click the mouse button or press the
Space Bar to display the information.
Monsoons (cont.)
• Cyclones, another kind of catastrophic
weather event, are equally destructive.
(pages 577–579)
Monsoons (cont.)
Compare and contrast South Asia’s
cycle of seasons with those of the
United States.
In most of the United States there are
four seasons. The general weather
pattern does not depend on the
seasonal monsoons, and the extremes
of hot, dry, cool, and wet are not as
drastic as those of South Asia.

oceans in summer and cold, dry
air from inland in winter
Click the mouse button or press the
Space Bar to display the answers.
A. monsoon
B. cyclone
Critical Thinking
Analyzing Information Analyze the
reaction of South Asia’s environment to
the monsoons.
The summer monsoon winds bring moist
ocean air from the southwest, which triggers
rainfall that supports agriculture in a region
without much other annual precipitation.
These winds can also trigger flooding. Winter
monsoons bring dry air that may cause
droughts.
Click the mouse button or press the
Space Bar to display the answer.
Critical Thinking
Decision Making Suppose that you wanted
to establish a lumber business in South Asia.
Where would you locate it? Why?
Critical Thinking
Comparing and Contrasting Are the
effects of the very hot temperatures in much
of South Asia more positive or more
negative? Explain.
The effects of the very hot temperatures are
probably more negative, because of the
effects on the soil (drying it out, removing
nutrients) and the possibility of drought in
a region with limited freshwater access.

G
Great Indian Desert
H
Mt. Everest and the Great Indian Desert
J
Mt. Everest
Test-Taking Tip Read the question carefully. The phrase based on
elevation is important. The Great Indian Desert is unsuited to farming,
but not because of its elevation. Once you apply the standard asked for
in the question, it is easy to eliminate wrong answers.
Click the mouse button or press the
Space Bar to display the answer.
Mount Everest was named for a man who never saw
it. British scientist George Everest–pronounced
EEV•ruhst–headed the Great Trigonometrical Survey
that measured the Indian subcontinent in the 1800s.
Mistakenly thinking the peak had no local name,
British mapmakers assigned Everest’s name to it.
India Rice is so important to South Asian culture that
the Hindi phrase for “Have you eaten?” translates
literally as “Have you taken rice?”
Reading an Elevation Profile
If you were planning a long-distance cycling expedition, you
might want to check elevations of places along your route.
Elevation, the vertical distance above sea level of a place or
landform, can be shown in a number of ways. An elevation
profile gives you elevation information in a visual form.
Reading an Elevation Profile
Learning the Skill
An elevation profile presents visual information about the
elevation of a particular area, route, or landform in a twodimensional way. The base of an elevation profile is sea level,
the point from which land elevation is measured. A vertical
scale measures elevation above sea level.
Reading an Elevation Profile
Learning the Skill
Reading an elevation profile is similar to reading a line graph.
The vertical scale corresponds to the y-axis. In some
elevation profiles, a horizontal scale, corresponding to the xaxis, measures the length of the route, area, or landform in
miles or kilometers. The profile, or top edge of the landscape
shown, corresponds to the line in a line graph. This line
shows elevation at specific points. Some elevation profiles
provide information on more than one route, area, or
landform, using different colors or patterns to distinguish each
profile.
Reading an Elevation Profile
Learning the Skill
Follow these steps to read an elevation profile: 
• Look at the landscape profile as a whole. This will give
you a general sense of the variations in elevation shown. 
• Find the highest and lowest points. Use the vertical scale
to find their elevations. Calculate the approximate difference
in elevation between the highest and lowest points. 
• Use your finger to trace the profile. If your finger must
jump up and down to follow the profile, the area has
dramatic differences in elevation. 
• If more than one area or landform is profiled, follow the
procedure for each profile. Then use the information to
compare the profiled areas.
