Introduction Section 1:The Land Section 2:Climate and Vegetation Visual Summary Chapter Menu
Millions of years ago, tectonic activity formed the landmasses of Southeast Asia. Straddling the Equator, the peninsulas and islands of the region stretch from the Asian mainland almost to Australia. A study of the physical geography of Southeast Asia will explain its beginnings, its natural barriers of mountains and water, its tempestuous volcanoes, and its abundant natural resources. Chapter Intro 1
Section 1:The Land Physical processes shape Earth’s surface. Southeast Asia’s landmasses were formed millions of years ago by tectonic plate collisions and related volcanic eruptions. Chapter Intro 2
Section 2: Climate and Vegetation The characteristics and distribution of ecosystems help people understand environmental issues. The climates of Southeast Asia support diverse ecosystems and natural habitats, some of which have already disappeared or are endangered because of logging and urbanization. Chapter Intro 3
