Geography: The landscape of Thailand is marked by high mountain ranges in the north and two plateaus – one in the upland and in the centre. The Chao Phraya River is its main river that drains along with its tributaries into the Bay of Bangkok. The Khorat Plateau and the Mun River are in the northeastern part of Thailand where the river drains into the Mekong River. The famous Rice Bowl of Asia is the province of central Thailand. Southern Thailand is famous for tourist spots, rubber and palm oil plantations.
