2. Describe the formation of ocean currents.
Answer:Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. ... These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
3. Name the major warm and cold currents of the Atlantic Ocean and explain their impact on the climatic
conditions of the coastal areas.
Answer:North equatorial current is a significant Pacific and Atlantic Ocean current that flows east-to-west between about 10° north and 20° north. This current is generated because of upwelling of cold-water near the west coast of Africa. This warm current is also pushed westward by the cold Canary current.
4. 'The relationship between winds and the currents is best seen in the Indian ocean'. Discuss.
Answer:The nature of the monsoon in the Indian subcontinent greatly influence the currents in the Indian Ocean and no permanent current is found in the north part of Indian Ocean. ... The offshore movement of SW monsoon wind creates an upwelling zone on the west coast of Africa which again strengthens the SW monsoon drift.
