Question 1

Question 1Describe the factors that affect the climate of Asia.

Accepted Answer

The factors that affect the climate of Asia are-Latitudes — The vast extent of Asia covering 10°S to 80°N latitudes experiences all the types of climate ranging from hot and wet Equatorial type in the south to dry and cold Tundra type in the north.Distance from the sea — Places close to the sea experience moderate climate, whereas places in the interior experience extremes of climate.Monsoon winds — During summer, the southwest monsoon winds blow onshore. They pick up moisture from the Arabian sea and give heavy rainfall. During winter, they blow offshore as dry northeast monsoons and do not give any rainfall.Direction of the mountain ranges — The east west trend of Himalayas in South Asia, prevents the cold winds from Central Asia to enter the subcontinent in winter. They force the monsoon winds to shed their moisture in the south during the rainy season.Ocean currents — The cold and warm ocean currents affect the climate of a region. For example, the cold Oyashio current, which comes from the north and washes the western coast of Japan, affects the climate of Japan by making it extremely cold, whereas the east coast of Japan is washed by the warm Kuroshio current that makes the winter milder.

Question 2

Question 2Compare and contrast the summer and winter conditions of Asia.

Accepted Answer

Summer conditions in AsiaWinter conditions in AsiaDuring summer, the sun is directly above the Tropic of Cancer, the main landmass of Asia develops low pressure. The surrounding seas being cooler, develop high pressure. Since the winds blow over the oceans, they pick up a lot of moisture and give heavy rainfall in South Asia. These are known as southwest monsoon winds as they blow from southwest to northeast.During winter, the sun is directly above the Tropic of Capricorn, Central Asia becomes extremely cold and develops high pressure. The surrounding oceans are relatively warm and have low pressure over them. The winds start blowing from land to sea. The winds are dry and do not bring rain. These cold winds blowing southward are checked by the Himalayas in South Asia. During winter, northeast monsoon winds blow from northeast to southwest. They pick up moisture from Bay of Bengal and give rainfall to eastern coast of India. In the south western part of Asia, western disturbances originating in the Mediterranean Sea bring winter rainfall.

Question 3

Question 4Compare and contrast the natural vegetation of equatorial region and Tundra region.

Accepted Answer

Natural vegetation of Equatorial regionNatural vegetation of Tundra regionEvergreen rain forests are found in Malaysia, Indonesia and parts of Philippines.This type of vegetation is found in northern Russia, bordering the Arctic ocean.These forests consist of a variety of trees, palms and ferns with dense undergrowth of shrubs and creepers. Examples of trees are rosewood, ebony etc. This area receives a large amount of rainfall due to hot and wet climate.The vegetation consists of mosses and lichens. This area is covered with snow for most of the year.

Question 4

Question 5How do Himalayas affect the climate of Asia?

Accepted Answer

The east west trend of Himalayas in South Asia, prevents the cold winds from Central Asia to enter the subcontinent in winter. They force the monsoon winds to shed their moisture in the south during the rainy season.

Question 5

Question 3Monsoon and taiga type of vegetation.

Accepted Answer

Monsoon type of vegetationTaiga type of vegetationMonsoon type of vegetation is found in south, southeast and east Asia.Taiga forests are found in a broad belt in the central part of Siberia, located to the south of Tundra region.Monsoon forests consists of broad leaved deciduous forests. Species like teak, sal, sandalwood, peepal etc., are found here.The main trees of this region are pine, fir, cedar and spruce.The trees shed their leaves in dry winter season.These trees have needle shaped leaves and can withstand extremely cold climate.
