\nAtlantic<\/td>\n – Puerto Rico \n– South sandwich \n– Cayman<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n(iv) What is a thermocline? \nAnswer: \nThe temperature-depth profile for ocean water shows how temperature decreases with increasing depth. The profile shows a boundary region between surface waters of the ocean and deeper layers. This boundary region, where there is a rapid decrease of temperature, is called the thermocline. \n <\/p>\n
(v) When you move into the ocean, what thermal layers would you encounter? Why the temperature varies with depth? \nAnswer: \nAs we move into the ocean, we would encounter three layers from surface to the bottom. The temperature varies with depth. Latitude, unequal distribution of land and water affects the distribution of temperature. Temperature decreases with depth because sun\u2019s rays become more and more slanting and thus the amount of insolation decreases polewards.<\/p>\n
(vi) What is salinity of sea water? \nAnswer: \nSalinity is the total amount of dissolved salts in sea water. It is calculated as the amount of salt dissolved in 1000 gms of sea water.<\/p>\n
Question 3. \nAnswer the following questions in about 150 words each : \n(i) How are various elements of hydrological cycle interrelated? \nAnswer: \nHydrological cycle is one of the most fundamental cycles that maintains life on earth. The hydrological cycle depends basically on the interrelationship between the circulation of ocean water and that of the atmosphefe. The interrelationship between these elements is a very complex process.<\/p>\n
Water withdrawn from the oceans into the atmosphere by process of evaporation depends on air and sea temperatures and on wind strength and humidity. Another relationship between ocean and hydrological cycle is raising up minute particles of salt and other minerals from the sea.<\/p>\n
The salt returns to the oceans through rainfall, rivers and other phases of the hydrological cycle. Hydrological cycle is concerned with water in all its forms, i.e., solid (ice), liquid (water) and gas (water vapour). The interaction between ocean and atmosphere involves all the three states of water – solid, liquid and gaseous.<\/p>\n

(ii) Examine the factors that influence the temperature distribution of the oceans. \nAnswer: \nThe major source of temperature of the oceanic water is the sun. The various factors which affect the distribution of temperature of the ocean water include ‘attitude, unequal distribution of land and water, prevailing wind, ocean currents, and minor factors like submarine ridges, local weather condition and shape and size of the sea. On an average, the temperature of the surface water of the oceans is 26.7\u00b0C. It decreases gradually from equator to the poles.<\/p>\n","protected":false},"excerpt":{"rendered":"
