Question 2.
\nAnswer the following in about 30 words each :
\n(i) How does the unequal distribution of heat over the planet earth in space and time cause variations in weather and climate?
\nAnswer:
\nThe amount of heat received by different parts of the earth is not the same. This variation causes pressure differences in the atmosphere. This leads to transfer of heat from one region to the other by winds.<\/p>\n

(ii) What are the factors that control temperature distribution on the surface of the earth?
\nAnswer:
\nThe factors controlling temperature distribution are :<\/p>\n
