1. The Northern Lowlands
The Northern Lowlands are the extensive plain areas that comprise of several patches of lowlands of this large continent.
The major lowlands are:
Great Siberian plain
- It extends between the Ural Mountains in the west and the river Lena in the east. It is the largest lowland in the world covering an area of 1,200,000 square miles approx.
- It is the area adjoining Amur river and its tributaries of the northern part of China with an area of 135,000 square miles approx.
Great Plains of China
- It is contributed by two major rivers of China, Hwang Ho and Yangtze river which covers an area of 158,000 square miles approx.
2. The Central Mountains
- These are the prominent and extensive mountain ranges that cover the parts of Central Asia.
- They consist of Pamir and Tian Shan ranges and extending across portions of Afghanistan, China, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan.
- These mountain ranges are designated as biodiversity hot spots by Conservation International which covers several montanes and alpine ecoregions of Central Asia.
- It encompasses several habitat types, including montane grasslands and shrublands, temperate coniferous forests, and alpine tundra.
- A mountain knot is a junction of two or more mountain ranges. The two main mountain knots in Asia are:
- The Pamir Knot is the junction of five mountain ranges they are the Sulaiman, the Hindu Kush, the Kunlun, the Karakoram, and the Himalayan ranges. Mount Everest, the highest peak in the world in the Himalayan range.
- The Armenian Knot is connected to the Pamir Knot by the Elburz and the Zagros Ranges that originate in the Armenian Knot. The Tien Shan and the Altai are other mountain ranges in Asia.

A peninsula is a mass of land surrounded by water but attached to the mainland. The Deccan plateau region is also a peninsula. The major peninsulas of Arabia, India, and Malay are in southern Asia. The Kamchatka peninsula lies in northeastern Asia.
Asia has some big deserts such as the Gobi, the Takla Makan, the Thar, the Kara-Kum, and the Rub-al-Khali Deserts.
The Rub’ al Khali desert, considered the world’s largest sand sea, covers an area larger than France across Saudi Arabia, Oman, the United Arab Emirates, and Yemen.
6. (a) Islands of Asia
Asia also has a cluster of islands, also called an archipelago. An archipelago sometimes called an island group or island chain, which is formed close to each other in large clusters. Indonesia, Philippines, Japan, Andaman, and Nicobar are some examples of archipelagos.
6. (b) Drainage of Asia
The drainage of Asia consists of mighty oceans, extensive seas, lengthy rivers, and their tributaries and distributaries, major lakes, etc.
Oceans: Asian continent is surrounded by three major ocean from three sides such as
The Pacific Ocean – It covers the eastern part of Asia where major rivers of eastern Asia drain, such as Menam Mekong, Xi Jiang, Chang Xiang, Huang Ho, and Amur.
The Indian Ocean – It covers the southern part of Asia and the major rivers that flow into the Indian Ocean are Tigris, Euprates, the Indus, the Ganga, Brahmaputra, Irrawaddy, Salween.
The Arctic Ocean – It covers the Noth east part of Asia and consists of three major rivers such as Ob, Yenisey, and Lena.
As the continent is covered by sea from its three sides, It has also characterized by the long stretch of bay and gulf.
Major seas contributing to Asian Drainage are Andaman Sea, Arabian Sea, Banda Sea, Barents Sea, Bering Sea, Black Sea, Caspian Sea, East Siberian Sea, Java Sea, Kara Sea, Laccadive Sea, Sea of Japan, Sea of Okhotsk. The South China Sea and the Yellow Sea.

Major lakes of Asia are
- Lake Baikal, Onega, Ladoga, and Peipus in Russia;
- Lake Akan, Mashu, Biwa, Shikotsu in Japan;
- Qinghai Lake, Lake Khanka in China;
- Dal Lake, Chilka, Vembanada, Pullicat and Sukhna in India;
- Lake Matano and Toba in Indonesia, etc.
Baikal is the deepest lake in the world. It is in Southern Siberia, Russia.
- Lake Baikal, located in southern Russia, is the deepest lake in the world, reaching a depth of 1,620 meters (5,315 feet). The lake contains 20 percent of the world’s unfrozen fresh water, making it the largest reservoir on Earth. It is also the world’s oldest lake, at 25 million years old.
- The Yangtze is the longest river in Asia and the third-longest in the world (behind the Amazon of South America and the Nile of Africa). Reaching 6,300 kilometers (3,915 miles) in length, the Yangtze moves east from the glaciers of the Tibetan Plateau to the river’s mouth on the East China Sea. The Yangtze is considered the lifeblood of China.
- The Tigris and Euphrates Rivers begin in the highlands of eastern Turkey and flow through Syria and Iraq, joining in the city of Qurna, Iraq, before emptying into the Persian Gulf. The land between the two rivers, known as Mesopotamia, was the center of the earliest civilizations, including Sumer and the Akkadian Empire.
- The Persian Gulf has an area of more than 234,000 square kilometers (90,000 square miles). It borders Iran, Oman, United Arab Emirates, Saudi Arabia, Qatar, Bahrain, Kuwait, and Iraq. The gulf is subject to high rates of evaporation, making it shallow and extremely salty.
- The Sea of Okhotsk covers 1.5 million square kilometers (611,000 square miles) between the Russian mainland and the Kamchatka Peninsula.
- The Bay of Bengal is the largest bay in the world, covering almost 2.2 million square kilometers (839,000 square miles) and bordering Bangladesh, India, Sri Lanka, and Burma. Many large rivers, including the Ganges and Brahmaputra, empty into the bay.

Asia’s climate can be most generally divided into three zones:
- The continent’s north/central zone is affected by cold and dry Arctic winds, especially the Siberia region of Russia.
- Hardier grains, such as barley, buckwheat, millet, oats, and wheat, are grown in the central and southern areas of this zone, where permanent frosts inhibit plant growth.
- Animal husbandry is also very important in this zone. In Mongolia, for example, 75 percent of agricultural land is allocated to the rearing of livestock, such as sheep, goats, and cattle.
- The southwest zone is a dry, hot region that stretches from the Gobi Desert in Mongolia through Pakistan, Iran, and into the Arabian Peninsula.
- This zone has very few areas with enough moisture and precipitation to produce crops. Grains, such as barley and corn, are the principal irrigated crops of some countries.
- Dates, figs, apricots, olives, onions, grapes, and cherries are the most important of these fruit and vegetable crops.
- The southeast zone is greatly affected by the summer monsoon season.
- Rice is one of Asia’s most important agricultural commodities and a major food staple of the entire continent.
- Many regions where rainfall is less, grow a large amount of wheat.
- Southeast Asia is also a major producer of tropical fruits, such as mango, papaya, and pineapple. India is the world’s largest mango-producing nation, accounting for roughly 40 percent of total global output.
- China, India, Russia, and Indonesia are the continent’s most productive mining economies. These countries extract many of the same minerals.
- China is the world’s largest producer of aluminum, gold, tin, and coal.
- India is also a major producer of aluminum and iron ore, along with other minerals such as barite (used in drilling fluids), chromium (used in steel production and dyes), and manganese (used in steel production).
- Russia is a major producer of coal, tungsten (used in steel production), diamonds, iron, and steel.
- Indonesia is a major producer of coal, gold, copper, and tin.
- Countries on the Arabian Peninsula have the world’s largest deposits of oil and natural gas. These fossil fuels are drilled for energy and fuel.
- The oil found throughout the Arabian Peninsula and the Middle East is of the highest quality: light sweet crude.
- Light sweet crude oil is used to make gasoline, kerosene, and diesel fuels.
- In 2010, Saudi Arabia was the world’s largest manufacturer of petroleum liquids, producing 10.07 million barrels of liquid fuels every day. (An oil barrel is 159 liters or 42 gallons.) It also has the world’s largest oil reserves, at roughly 250 billion barrels.
- Russia has oil reserves in Siberia and massive natural gas reserves throughout the Arctic.
- Russia and Iran have the world’s largest reserves of natural gas, while the US produces the most.
