Dry fish , copra and Jaggery(gur) used to be brought to India and Sri Lanka from Lakshadweep and Maldives. Rice was taken from India and Sri Lanka to these islands. Which winds in ancient times would take food grains to these islands and which would bring copra, dry fish and jaggery to Indian and Sri Lanka.

B. Advancing monsoon in former and retreating monsoon in latter case,
C. Retreating monsoon in former and advancing monsoon in the latter case.
D. None of the above.
4. Both these places lie at the same latitude but the months of maximum rainfall is different at both the places , what could be the reason for this? which place receives more annual rainfall and why ?
5. These two places are only 30 kilometres apart but there is a great variation in the amount of rainfall . What could be the reason for it ?
6. how will you connect the three pictures ?
i. Which of the following place experiences wet equatorial climate and which of the following place experiences monsoon type of climate ?
On what basis you say it is equatorial and monsoon type of climate?
ii. Which of the following city experiences high humidity throughout the year.
iii. Compare the range of temperature of the two places ?
iv. Other than solar energy which clean energy can be generated at Lagos ? On what basis you can say that ?
7. STUDY THE CLIMATIC TABLE OF MANILA AND DARWIN AND ANSWER THE BELOW QUESTIONS.
WHAT WOULD SERVE AS A CLUE FOR EXPLAINING THE PHENOMENON
A. LONGITUDE
B. LATITUDE
C. POSITION OF ITCZ IN DIFFERENT MONTHS OF THE YEAR.
D. BOTH B & C
ANSWER KEY
1. Condition A is most favourable for all the places because the economy of Peru is dependant on fisheries and high pressure condition near Peruvian coast suggest the presence of cold water which means upwelling of nutrients is taking place . Low pressure condition in Western Pacific is favourable for rainfall in Asia . The
economy of Asia is dependant on agriculture .
2. The waters off the Peruvian coast had abundance of fish since time immemorial and the human population to consume the fishes were quite negligible. Millions of birds have been taking advantage of this situation for several hundred thousand years . Their dropping have resulted in the formation of Guanay mountains.
3. C. Retreating monsoon in former case and advancing monsoon in latter case.
4. Mangalore gets most of its rains due to advancing monsoon and Chennai gets most of its rains due to retreating ( north east ) monsoon . Chennai gets its rains due to retreating monsoon because it lies on the coast of Bay of Bengal . Mangalore gets higher annual rainfall than Chennai.
5. This is a classic example of orographic rainfall . Mahabaleshwar gets more rains because it lies in the windward side and Pune lies on the leeward side of western Ghats .
6. i. Lagos experiences equatorial climate and Kano experience monsoon type of climate .
ii. Lagos experience more humidity.
iii. range of temperature is higher in Kano.
iv. see the orange line at the bottom ( wind energy)
7. They lie in different hemispheres.
