1.	Look at the map of ocean currents and answer the following:(i) How does the Humboldt current affect the climate of the South America?(ii) In which oceans are counter equatorial currents not observed and why?(iii) Which currents are absent in the northern part of the Indian Ocean and why?(iv) In which regions do the cold and warm ocean currents meet?
Answer» (i) Humboldt current is a cold ocean current and so it decreases the amount of precipitation and temperature on the western coastal region of the South America. (ii) Counter equatorial currents are not observed in Arctic Ocean and Southern Ocean. These oceans are located near the polar regions. Therefore, the effects of trade winds is found to be less in these oceans Therefore, counter equatorial currents are not observed in these oceans. (iii) Cold currents are absent in the northern part of the Indian Ocean. The northern part of Indian Ocean is included in the temperate zone. So cold currents are absent in the northern part of the Indian Ocean. (iv) The cold and warm ocean currents S meet in the following regions: 1. North Atlantic Ocean (cold Labrador current and warm Gulf stream current) 2. North Pacific Ocean (cold Oyashio current and warm ! Kurishio current) 3. South Atlantic Ocean ! (cold Falkland current and warm Brazil current) 4. South Pacific Ocean (cold South Polar current and warm East Australian current) 5. Indian Ocean (cold South Polar i current and Agulhas Current)

Answer»

(i) Humboldt current is a cold ocean current and so it decreases the amount of precipitation and temperature on the western coastal region of the South America.

(ii) Counter equatorial currents are not observed in Arctic Ocean and Southern Ocean. These oceans are located near the polar regions. Therefore, the effects of trade winds is found to be less in these oceans Therefore, counter equatorial currents are not observed in these oceans.

(iii) Cold currents are absent in the northern part of the Indian Ocean. The northern part of Indian Ocean is included in the temperate zone. So cold currents are absent in the northern part of the Indian Ocean.

(iv) The cold and warm ocean currents S meet in the following regions:

1. North Atlantic Ocean (cold Labrador current and warm Gulf stream current)

2. North Pacific Ocean (cold Oyashio current and warm ! Kurishio current)

3. South Atlantic Ocean ! (cold Falkland current and warm Brazil current)

4. South Pacific Ocean (cold South Polar current and warm East Australian current)

5. Indian Ocean (cold South Polar i current and Agulhas Current)
