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. (page 569) Click the mouse button or press the Space Bar to display the answer. 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) Click the mouse button or press the Space Bar to display the information. 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 Space Bar to display the information. 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) Click the mouse button or press the Space Bar to display the information. A Land of Great Variety (cont.) - Sri Lanka once was part of the subcontinent. - Maldives is a chain of coral atolls and volcanic outcroppings. (pages 570–571) Click the mouse button or press the Space Bar to display the information. A Land of Great Variety (cont.) What major effect has the Vindhya Range had on India’s people? The Vindhya Range has physically divided India, giving rise to separate northern and southern cultures. (pages 570–571) Click the mouse button or press the Space Bar to display the answer. 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. (page 572) Click the mouse button or press the Space Bar to display the information. 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. (page 572) Click the mouse button or press the Space Bar to display the information. Major River Systems (cont.) - The Ganges Plain is also India’s most densely populated area. (page 572) Major River Systems (cont.) (page 572) Click the Speaker button to listen to the audio again. Major River Systems (cont.) Why do Hindus believe the waters of the Ganges are sacred? Possible answer: The Ganges is the source of the freshwater that allows everyone to drink, to bathe, and to have good harvests every year. It is literally a source of life. (page 572) Click the mouse button or press the Space Bar to display the answer. Natural Resources • Water South Asia’s rivers provide the region with hydroelectric power, transportation, drinking water, and fish. • Although rivers cross national boundaries, countries sometimes cooperate in managing this important resource.

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. (pages 577–579) Click the mouse button or press the Space Bar to display the answer. Checking for Understanding Define Match each definition in the left column with the appropriate term in the right column. __ B 1. storm with heavy rains and high winds that blow in a circular pattern around an area of low atmospheric pressure __ A 2. in Asia, seasonal wind that brings warm, moist air from the 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. Click the mouse button or press the Space Bar to display the answer. Analyzing Maps Region Compare the maps of South Asia’s climate and vegetation below. Explain how climate and vegetation are related in the region. Click the mouse button or press the Space Bar to display the answer. Analyzing Maps Each climate has vegetation typical of its area.

Reviewing Facts Section 1: The Land Why might the region of South Asia be referred to as “a land of great variety”? The region might be referred to as “a land of great variety” because of its many different landforms, climates, and types of vegetation. Click the mouse button or press the Space Bar to display the answer. Reviewing Facts Section 1: The Land How have the mountains of the Vindhya Range affected the people of India? The mountains have affected the people of India by separating India into distinct northern and southern parts. The Vindhya Range has given rise to two different Indian cultures. Click the mouse button or press the Space Bar to display the answer. Reviewing Facts Section 1: The Land Why is the management of water resources important in South Asia? The management of water resources is important because the major rivers cross international boundaries. Access to freshwater is limited in much of the region, and most rainfall is limited to seasonal monsoons. Click the mouse button or press the Space Bar to display the answer. Reviewing Facts Section 2: Climate and Vegetation Where can you find a steppe climate region in South Asia? A steppe climate region can be found on the Deccan Plateau, and surrounding the Great Indian Desert except on the coast. Click the mouse button or press the Space Bar to display the answer. Reviewing Facts Section 2: Climate and Vegetation When do the three seasons found in much of South Asia occur, and how would you describe each? The hot season is from late February to June. The wet season is from June or July until September, and the cool season is from October to late February. Click the mouse button or press the Space Bar to display the answer. Reviewing Facts Section 2: Climate and Vegetation What factors enable South Asia’s rain forests to thrive? The rain forests thrive because they are directly in the path of the monsoon rains, with no mountains to block them. Click the mouse button or press the Space Bar to display the answer. Critical Thinking Identifying Cause and Effect In what way are the Himalaya responsible for the richness of the soil in the northern plains of the Indian subcontinent? The Himalaya block the summer monsoon winds and redirect the rainfall to the plains. Click the mouse button or press the Space Bar to display the answer. Critical Thinking Comparing and Contrasting What are the advantages and disadvantages of the monsoons to South Asia? The summer monsoon winds bring moist ocean air from the southwest, which triggers rainfall that supports agriculture. These winds can also trigger flooding.

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. Click the mouse button or press the Space Bar to display the information.
