  1. Southeast Asia Australia, Oceania, and Antarctica Unit 10

  2. Physical Geography of SE Asia Ch. 30

  3. Physical Geography of Australia, Oceania, & Antarctica Ch. 30

  4. The Land • Southeast Asia is a region of tropical beauty, with mountains ranges, volcanoes, and tropical rainforests dominating the landscape. • The region consists of: • the mainland • the Indochina Peninsula • the Malay Archipelago: 20,000 islands stretching from the Indian Ocean to the Pacific Ocean.

  5. The region of Australia, Oceania, and Antarctica is one of the most diverse in the world • It spans: • the tropical islands of the Pacific • the deserts and reefs of Australia • the mountains, lush valleys, and beaches of New Zealand • the ice and snow of Antarctica

  6. Peninsulas & Islands Southeast Asia was created by the collision of three tectonic plates and related volcanic activity and earthquakes • Mainland SE Asia • About ½ of SE Asia’s 14 countries are located on the mainland • The mainland is dominated by mountain ranges, which create both geographic and political boundaries • Laos is the only landlocked country • Island SE Asia • Island nations include: Brunei, East Timor, Indonesia, Singapore, & the Philippines • The mountains on the islands are volcanoes, many of which are still active • Indonesia is made up of 13,677 islands that span 3,000 mi • Singapore is one large island & 50 smaller ones • The Philippines is made of 7,000 islands, 11 of which are home to 95% of the population

  7. Australia: A Continent & a Country Australia, both a country and a continent, is dominated by the flat, dry interior • Mountains & Plateaus • The Great Dividing Range along the eastern coast separates this “outback” from the fertile east coast • The Western Plateau (Outback) covers 2/3 of the continent • the area includes 3 deserts • South of the deserts lies the Nullarbor Plain • Central Lowlands • Grassland & desert separates the Great Dividing Range from the Western Plateau • Very little rain • Below the surface lies the Great Artesian Basin

  8. Australia: A Continent & a Country • Great Barrier Reef • Along the northeastern shore lies the Great Barrier Reef • 2,500 coral reefs • National Park that is home to many species of tropical fish & sea creatures • Natural Resources • Australia has rich mineral resources and a thriving agriculture despite limited land use • Mineral resources include bauxite, coal, iron ore, lead, zinc, gold, nickel, opals, & petroleum

  9. Great Barrier Reef

  10. Physical Features • Mountains • SE Asia’s mountains create geographical & political boundaries • Some are active volcanoes • Broken down volcanic material provides fertile soil • Volcanoes of Indonesia & the Philippines • Java: home to one of the Ring of Fire’s most active areas, also home to 17 of Indonesia’s 100 active volcanoes • Krakatau (1883) • Mt. Pinatubo (1991) • Rivers • Rivers provide transportation and food, and their silt and deposits of sediment create fertile agricultural areas

  11. Oceania: Island Lands • Island Clusters • The island lands of Oceania are divided into three clusters • Melanesia- to the north & east of Australia • Micronesia- to the north of Melanesia • Polynesia- extending from Midway Island to New Zealand • Island Types • High Islands, Low Islands, & Continental Islands • High islands still experience active volcanoes and earthquakes • Low islands are atolls shaped by the buildup of coral reefs on the rims of submerged volcanoes • Most of the large islands of Oceania are continental islands

  12. New Zealand: A Rugged Landscape • New Zealand comprises two main islands called the North and South Islands • New Zealand is notable for its geographic isolation, being separated from Australia to the northwest by the Tasman Sea, approximately1250 miles across • Its closest neighbors to the north are New Caledonia, Fiji and Tonga • New Zealand's has two main islands • have beaches • ancient forests • snow-tipped mountains • lowlands and plateaus that support crops and livestock

  13. Antarctica: A White Plateau • Centered asymmetrically around the South Pole and largely south of the Antarctic Circle • Antarctica is the southernmost continent • surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. • It covers more than 5.4 million sq mi, making it the fifth-largest continent, about 1.3 times larger than Europe. The coastline measures 11,160 mi • By international agreement, activity on Antarctica is limited to scientific research

  14. Natural Resources The region has rich natural resources. In some countries, however, these resources remain underdeveloped • Energy Resources: • Fossil fuels are abundant, and Indonesia is a member or OPEC • Malaysia, Vietnam, the Philippines, & Brunei also have fossil fuel resources • Minerals & Gems: • Minerals and gems are also plentiful in the region • Indonesia: nickel, & iron • Philippines: copper • Malaysia: tin • Many areas have large quantities of precious gems • Myanmar has large deposits of minerals & gems but mining only employs less than 1% of their workers

  16. Natural Resources • Flora & Fauna: • Flora- • Southeast Asia's plant and animal life is diverse, with many species unique to the region • The vast array of flowers & plants contribute to the region’s economy • Thailand is one of the world’s leading exporter of orchids. Malaysia is a source of much of the world’s rubber, and Indonesia is the world’s largest supplier of plywood • Fauna- • SE Asia has a wide variety of animals including elephants, rhinoceroses, tigers, & orangutans. • Animals exclusive to the region include the Komodo dragon, & the bearded pig • Fishing: • Fishing is important to the region's economy and provides much of the people's diet • SE Asians consume more than twice the world’s rate • More than 2,500 species of fish live in the region • Fish farming is important to the region’s economy

  20. Tropical Climate Regions Southeast Asia owes much of its beauty to the monsoons, which bring abundant rains • Tropical Rain Forest Climate • Tropical rain forest climate dominates the region and is found on the islands and in coastal regions • Rain forests feature more than 145,000 species of flowering plants • Singapore: once covered by rainforest, now Singapore is entirely urbanized. Today 80% of the trees there are imported • Tropical Savanna Climate • Tropical savanna with tropical grasslands is found along the southeastern parts of Indonesia and across the Indochina Peninsula

  21. Tropical Climate Regions • Humid Subtropical Climate • Some parts of the region's mainland have a humid subtropical climate • the northern areas of Laos, Thailand, and Vietnam have lower temperatures • Highland Climate • Temperatures are even cooler in the highlands climate of the mountainous areas of Myanmar, New Guinea, and Borneo, where deciduous trees and evergreens grow

  22. Climate of Australia • Australia is a land of vast differences in climate and vegetation. • Moisture is blocked from reaching the Western Plateau and the surrounding areas, where desert and steppe climates are found. • The coastal areas have a variety of moister climates and support most of the country's agriculture

  23. Climate of Oceania • Most of Oceania has a tropical rain forest climate, but low islands get little rainfall and have only shrubs and grasses

  24. Climate of New Zealand • Most of New Zealand has a marine west coast climate, mountains can experience fierce winds and blizzards year-round. • The country's geographic isolation has led to unique plants such as kauri trees and manuka

  25. Climate of Antarctica • Antarctica is the earth's highest, driest, windiest, and coldest continent • Some species of mosses, algae, and lichens thrive along the coasts
