Accepted Answer

Asia is known as a Continent of Contrasts because of its political as well as physical geography.Physically, it has the highest mountain peaks including the Mount Everest in Nepal and many of the longest rivers. It has the earth's lowest surfaces, the shore of the Dead Sea, 392 m below sea level in Israel. The Plateau of Tibet is the highest and most expansive plateau.Climatically, it has recorded the highest temperature in Jacobabad in Pakistan and the lowest temperature in Verkhoyansk in Siberia. It receives the highest rainfall at Mawsynram near Cherrapunji in Meghalaya in India and has the largest area with less than 25 cm of rainfall per annum in desert regions.Its vegetation varies from mosses and lichens of the Arctic region to the lush green forests of the equatorial regions. It has some of the most densely populated regions of the world (like Hong Kong, China etc.) whereas some parts of it have scarce population (like Siberia).Asia has some of the world's most fertile river valleys like Ganga and Indus, Hwang Ho etc., which grow all kinds of rich crops and are densely populated. On the other hand, there are vast tracts where almost nothing can be grown and which sustain very small population, eg., Iran, Thar, Tibet etc.It is the birth place of great religions like Judaism, Christianity, Hinduism, Buddhism etc.

Question 5

Question 7Write short notes on(i) Northern Lowlands(ii) Great River Basins

Accepted Answer

(i) In Asia, there is a vast triangular expanse of lowlands stretching from the northeast of Siberia to the Ural mountains and the Caspian sea in the west.From the central Asian mountain range these islands slope towards the Arctic Ocean coast.This region is drained by three long rivers- Ob, Yenisei and Lena. These rivers flow northwards and empty into the Arctic Ocean.The vast lowland may be subdivided into parts-The Ob-Yenisei lowland in the northwestThe Turan plain in the southwestThe Siberian lowland in the northeast(ii) Many rivers originate from the snow-laden mountains and flow through plains bringing large quantity of fertile alluvial soils and deposit them in their respective valleys. This is how the great river basins are formed.These river basins are the most populated regions of Asia. They are-The Valley of Mesopotamia, formed by rivers Euphrates and Tigris.The Valley of Indus, formed by the river Indus and its five tributaries.The Valley of the Ganga and Brahmaputra, formed by the rivers Ganga and Brahmaputra and their tributaries.The Great Plains of China, formed by the three large rivers, the Huang Ho, the Chang Jiang and Sikiang.

Question 9

Question 1The Northernmost part of Asia is marshy.

Accepted Answer

There are occasional depressions in the Ob-Yenisei lowland. When the northern part of the rivers freeze during winter, the outlet of water to the Arctic Sea is sealed. The water overflows and the middle parts have floods. The flood water flows to the depressions and fills them up. This way, vast swamps and marshy areas are created in the northern lowlands of Asia. Hence, the Northernmost part of Asia is marshy.

Question 10

Question 3The lower courses and mouth of the rivers Ob, Yenisei and Lena remain frozen throughout the year.

Accepted Answer

The lower courses and mouth of the rivers Ob, Yenisei and Lena remain frozen throughout the year as they lie beyond the Arctic Circle and this region has extremely cold climate.
