Asia and Oceania: relief, hydrography, climate
Oceania
Due to its isolation from the rest of the world, Australia and Oceania has an incredibly high number of endemic species, or species that are found nowhere else on Earth. Plants native of Oceania are the eucalyptus, jacaranda, hibiscus, and breadfruit tree.
Oceania is the smallest continent on earth and it is mainly composed of thousands
of islands in the central and southern areas of the eastern Pacific.
Low islands are also called coral islands. They are made of the skeletons and living bodies of small marine animals called corals. Sometimes, coral islands barely reach above sea level—hence the name “low island.”
Asia
By size and population, Asia is the biggest continent in the world. With 44.5 million km2, including its adjacent islands, it covers 8,7% of the terrestrial surface of the earth and almost 30% of the emerged lands. Six of every ten inhabitants of the earth live in Asia.
Asia can be divided in five main physical regions: mountain systems, plateaus, plains, steppes and deserts; also important are freshwater ecosystems and saltwater ecosystems.
The landscape of central Asia: It is dominated by steppes, large flat
areas covered with grass without forests.
Baykal Lake: It is located south of Russia, is the deepest in the world (1,620
m). It contains 20% of the liquid fresh water in the world.
Central Asia is dominated by a steppe landscape, a large area of flat,
unforested grassland.
The Rub'al Khali desert: It is considered the largest sand sea in the world, covers an area larger than France across Saudi Arabia, Oman, the United Arab Emirates, and Yemen.
The western plain of Siberia: The West Siberian Plain, located in central Russia, is considered one of the world’s largest areas of continuous flatland. It extends from north to south about 2,400 kilometers and from west to east about 1,900 kilometers.
The Yangtze: It is the longest river in Asia and the third longest in the world
(behind the Amazon of South America and the Nile of Africa).
The Tibetan plateau: It is considered the largest and highest area that ever existed in the history of the earth. The plateau covers an area of sea level. It is known as the “Rooftop of the World”.
The Tigris and Euphrates rivers begin in the heights of Eastern Turkey and flow from Syria and Iraq joining in the city of Qurna, Iraq, before emptying into Thee persin gulf.

The Persian Gulf: It has an area of more than 234,000 km2. The seabed beneath the Persian Gulf contains an estimated 50 percent of the world’s oil reservers.
Iranian plateaus: It covers more than 3.6 million km2 and embraces most of Iran, Afghanistan and Pakistan.
The Bengal: It is the largest bay in the world, with an extension of almost 2.2
million km2. and bordering Bangladesh.
