1. 4.3—Southeast Asia Chapter Atlas

2. Vocabulary Peninsula—a land area almost surrounded by water Archipelago—a group of islands

3. Peninsulas and Archipelagos Southeast Asia is divided into two parts: Mainland Southeast Asia and Island Southeast Asia.

5. Physical Features Mainland Southeast Asia is dominated by rivers, river deltas and mountains. Most people live in the river valleys between mountains. However, there are a lot of people living in this region—too many to be supported by farms that exist only on flat land. For this reason, Southeast Asia makes extensive use of what is called terrace farming, where farmers cut strips of flat land out of the sides of hills and mountains to farm on. Additionally, farmers use a method called double- cropping where they grow two different kinds of plants on the same land at the same time.

6. Terrace Farming and Double-Cropping

7. Terrace farming and double-cropping is also used in China and the Koreas, with its small amount of arable land available. However, it is most widespread in Southeast Asia.

8. Vocabulary Tsunami—a tidal wave caused by an Earthquake under the ocean Monsoon—seasonal winds that bring dramatic change to an area’s climate Typhoon—tropical cyclones that form in the Pacific Ocean

9. Climate Southeast Asia experience extreme weather on a regular basis. Monsoons are winds that change direction with the season. In the winter, these winds come from the Pacific Ocean in the east. In the summer they come from the Indian Ocean in the west. Both times, the monsoons bring huge amounts of rainfall—sometime in the hundreds of inches. Another climate issue in Southeast Asia are typhoons, which are exactly like hurricanes, but form in the Pacific Ocean instead. Between monsoons and typhoons flooding is a serious issue in Southeast Asia.

10. Monsoons, Typhoons and Flooding

11. The Pacific “Ring of Fire” Southeast Asia lies along the Pacific Ring of Fire, the area of intense earthquake and volcano activity around the Pacific Ocean. Volcanoes and earthquakes are common in Southeast Asia, as well as tsunamis caused by deep-sea earthquakes.

14. The Pacific Ring of Fire Like monsoons and typhoons, earthquakes, volcanoes and tsunamis can be very destructive forces in Southeast Asia. Many people in the region live their lives according to the geography around them— they are well aware of the possible dangers of the environment. Even in recent history hundreds of thousands have died from all these events together.
