Topographic characteristics of Southeast Asia

Southeast Asia consists of Indian zhina Peninsula and Malay Archipelago. Indo-China Peninsula is high in the north and low in the south, with criss-crossing mountains and rivers. The Malay archipelago is rugged, with short rivers, mountains, unstable crust and many volcanic earthquakes. The isomorphism of the two forms the topographical features of Southeast Asia.

The importance of expanding the geographical location of Southeast Asia.

The geographical position of Southeast Asia is very important, connecting three continents (Asia, Africa and Oceania) and two oceans (Pacific Ocean and Indian Ocean). The Malacca Strait between the Malay Peninsula and Sumatra Island is about 900 kilometers long, and the narrowest point is only 37 kilometers. It is the shortest sea route and necessary passage from Northeast Asia to Europe and Africa via Southeast Asia, and has always been a battleground for military strategists and businessmen.

Southeast Asia is located at the "crossroads" connecting Asia and Oceania, and connecting the Pacific Ocean and the Indian Ocean. The Malacca Strait between Malay Peninsula and Sumatra Island is the shortest sea route between Northeast Asia and East Asia, and it must pass through Southeast Asia to South Asia, West Asia, Africa and Europe. It is called Japan's "lifeline at sea" and its geographical location is very important.
