The pleura is a thin membrane that lines the surface of the lungs and the inside of the chest wall outside the lungs. In pleural effusions, fluid builds up in the space between the layers of pleura.
Major Landform regions of Australia See also. The Australian continent is broadly divided into 4 major landform regions, each of which is comprised of smaller-scale constituent landform regions-eastern highlands, central lowlands, western plateau and the coastal plains.he lowest point on the Australian continent, Lake Eyre, is also situated in this region. It also includes inselbergs such as Uluru and Kata Tjuta. About 38 % of the Australian continent is less than 200 m above sea level (so far), much of it in the Central lowlands.
The largest and highest plateau in the world is the Tibetan Plateau, called the  roof of the world , which is still being formed by the collisions of the Indo-Australian and Eurasian tectonic plates. The Tibetan plateau covers approximately 2,500,000 km 2 (970,000 sq mi), at about 5,000 m (16,000 ft) above sea level.The plateau is sufficiently high enough to reverse the Hadley cell convection cycles and to drive the monsoons of India towards the south.ome other major plateaus in Asia are: Armenian Highlands (~400,000 km 2 (150,000 sq mi), elevation 900-2100m), Iranian plateau (~3,700,000 km 2 (1,400,000 sq mi), elevation 300-1500m), Anatolian Plateau, Mongolian Plateau (~2,600,000 km 2 (1,000,000 sq mi), elevation 1000-1500m), and the Deccan Plateau.
