(b) X is part of the Brahmaputra Valley known as
the Assam region. Here, the relief is rugged, nountainous, and thickly forested, providing: little land for agricultural purpose. It is extremely wet here since the onshore south-west monsoon brings at least 200 inches. annually. Its excessive humidity is thus unhealthy for human beings. In addition, the heavy rainfall in the hot season may cause floods'in the valleye. Due to the nature of its relief, many areas are inaccessible, so communication on a whole is difficult. That is why it is so sparsely populated.
(c)
1.(a)
(6)
Y is situated in the Thar Desert. Obviously, the density of population is largely affected by its aridity because the rainfall here is less than 10 inches annually. The high temperature
throughout the year (about 95 F) is another
drawback. Scarcity of vainfall together with
intense evaporation make it impossible to grow
crops as little water is available for
irrigation purpose. Under such adverse conditions the area is, undoubtedly sparsely populated.
From the table, we can see that Calcutta has a lower annual range of temperature while Hong Kong has a high annual range, and that Hong Kong has a lower average January temperature than Calcutta. This is because Hong Kong is often affected by cold air coming from North China or Siberia in winter whereas Calcutta is not affected by such cold sir as it is sheltered by the high Himalayas which prevente the cold air from penetrating into the sub-continent of India.
With regard to rainfall, Hong Kong has a higher average annual amount. We can also see from the table that Hong Kong receivea more rain from November to January. This is because the North-east monsoon may bring rain to Hong Kong after crossing the South China Sea while in Calcutta, the north-easterly winds in winte
are offshore winds, therefore bring no rain. The higher average annual amount in Hong Kong say also be due to the fact that Hong Kong is frequently affected by typhoons which may brina torrential rain.
