First of all, I partially agree that geographically, Southeast Asia is a single unit. When we mention geography we are concerned about the region’s location, as well as physical characteristics such as land, river and mountains. Southeast Asian countries are all located around the same area and this naturally makes these countries geographically similar since they are near one another and not divided into regions which have different locations, climates and habitats. To be precise, Southeast Asia is geographically located between south of China, east of India and north of Australia, and this region lies on the intersection of geological plates with heavy seismic and volcanic activity which occurs periodically and affects the people living in Southeast Asia in one way or another. This shows that Southeast Asian countries are all located in the same region and hence they are a single geographical unit.
However, I also disagree to a certain extent that geographically, Southeast Asia is a single unit. Like previously mentioned, geography is also about the region’s landscape features. With a huge area of approximately 4000000km2 that is divided by the sea and rivers, Southeast Asia sure does have differences
