No! You must go atleast once to have a lifetime experience of Himalayas. If you would have more time, take a bike and make a group trip from Chandigarh to upper reaches of Himalayas in J&K. You will find gigantic features - Indus destroying the great mountains creating 1 km deep gorges, something similar to Death Valley of California! Ask someone who visited Africa; just see his photos. The huge deserts in the background would open your yaws. The dense jungles of River Congo will make you feel like a night even during full sunlight. If someone known has gone to Europe for a honeymoon, just ask him his experience. The beautiful beaches and lakes of Europe are the proof that if man desires, he can maintain the endless beauty of our earth. Life is too short. Nature has given us bountiful features; regional geography is all about to live nature! crackcrackIAS.IASCOM.COM 7 Physical Geography of Asia including Important Geopolitical Regions • Asia accounts for one-third of world’s land area and about 60% of its population. • Asia– Largest continent both in area and in population. • Tropic of Cancer in Middle East passes through Saudi Arabia, U.A.E. and Oman. Muscat (Capital of Oman) is located on it. It also passes through India, Bangladesh & Myanmar besides China and Taiwan. • Persian Gulf touches Saudi Arabia, U.A.E., Kuwait, Iraq & Iran, Oman & Bahrain. PHYSICAL FEATURES NORTHERN LOWLANDS (SIBERIAN PLAINS) • Plains between Ural Mountains in the West and Lena River in the east are called as Siberian Plains • Drained by Rivers Ob, Yenisei and Lena. • Lake Baikal – deepest lake of the world is located here. MOUNTAINS • Pamir Knot (Plateau) is the meeting place of several ranges of Asia. • This Plateau is highest in the world and known as “Roof of the world”. • Hindu Kush extends to the west, Tien Shan towards N. East, Kunlun to east and the Karakoram and Himalayas to the S-E. • To the west of Hindu Kush, two ranges of Mountain ranges diverge. In North Elburz (extend along south of Caspian Sea) and in South Zagros Mountains (extend along Arabian Sea and Overlooks Persian Gulf). • Elburz and Zagros Mountains enclose the Plateau of Iran. • These two ranges converge in the west at the knot of Mount Ararat. • Again two groups of Mountain ranges diverge westward from Mount Ararat, Pontic in the north and Taurus in the south. • Plateau of Anatolia is enclosed between Pontic and Taurus. • South Eastward of Pamir lies Karakoram Range and Himalayan range. • K2 (Godwin Austin in POK) is the highest Peak of Karakoram, whereas Mt. Everest is highest peak in the Great Himalayas. • Between these two ranges in south and Kunlun in the north, is the crackIAS.COM 8 Tibetan Plateau. • Further north, Tarim basin is located between Kunlun in south and Tien Shan in north. THE SOUTHERN PLATEAUS • Having older rocks than that of Mountains ranges • Plateau of Arabia, Deccan Plateau and Plateau of Yunnan are its parts THE GREAT RIVER VALLEYS • Tigris & Euphrates (Iraq). • Baghdad is located on river Tigris. Both of these fall into Persian Gulf. • Ancient Mesopotamian culture flourished between these two rivers. • Indus (Pakistan) • Ganga-Brahmaputra (India and Bangladesh) • Ayeyarwaddy or Irrawaddy (Myanmar) • Mekong (South-East Asian countries) • Sikiang, Chang Jiang (Yang-Tse-Kiang) and Huang He (Hwang-Ho) in China crackIAS.COM 9 THE ISLAND GROUPS • Indonesia, Philippines and Japan. • Most of these islands have Mountains core surrounded by narrow coastal plains, have extremely fertile soil (basically volcanic ash) CLIMATE WINTERS • Interior part of Asia becomes extremely cold, temperature decreases, air contracts forming high pressure area over Mongolia. Dry winds blow outward. Therefore most of the parts of Asia do not get rain though while blowing over the sea, winds pick up moisture and cause rainfall in some areas. • Oymyakon in N-E Siberia is the coldest place in the Northern Hemisphere [Mean January Temperature (- 45oF)]. SUMMERS • Temperature rises in the interior parts of Asia, air expands, create low pressure areas. Now High Pressure areas are located over oceans and winds starts blowing towards low pressure areas, causing rainfall in most of the areas. • Mawsynram in Meghalaya (India) is the wettest place (place with the highest average annual rainfall) in the world; however Mt Waialeale in Hawaii Island (USA) recorded highest annual average rainfall (11,680 mm) in 2007.

Grown in Pakistan, India, China, Thailand and Indonesia.
