Happy ! Have you thought about Thailand, the “Golden Axe,” today?
“Thailand is divided into five distinct physiographic regions: the folded mountains in the north and west, the Khorat Plateau in the northeast, the Chao Phraya River basin in the center, the maritime corner of the central region in the southeast, and the long, slender peninsular portion in the southwest.
The northern mountains, the southeastern continuation of the uplift process that formed the Himalayas, extend southward along the Thai-Myanmar border and reach as far south as northern Malaysia. Long granitic ridges were formed when great masses of molten rock forced their way upward through the older sedimentary strata. Peaks average about 5,200 feet (1,600 meters) above sea level. Mount Inthanon, at 8,481 feet (2,585 meters) the highest in the country, is in northwestern Thailand, near the historical city of Chiang Mai. The city is overshadowed by Mount Suthep, site of a famous Buddhist shrine and the royal summer palace.
The northeast is coterminous with the Khorat Plateau, a vast tableland bounded by the Mekong River on the north and east. The interior has low hills and small lakes.
Situated between the northern and western mountain ranges and the Khorat Plateau is the extensive Chao Phraya River basin, which is the cultural and economic heartland of Thailand. The region, sometimes called the Central Plain, consists of two portions: heavily dissected rolling plains in the north and the flat, low-lying floodplain and delta of the Chao Phraya in the south. It was formed by the outwash of immense quantities of sediment brought down from the mountains by the Chao Phraya’s tributaries, which produced vast fan-shaped alluvial deposits.
The generally rolling countryside of the southeast has high hills in the center and along the eastern boundary with Cambodia. The hills, reaching nearly to the sea, create a markedly indented coastline fringed with many islands.
The southwestern portion of the country consists of a peninsula with a mountainous spine and a gently sloping sandy coastline. Higher mountains reaching about 4,900 feet (1,500 meters) line the peninsula on the west and contain narrow passes linking Thailand and Myanmar.”
