#98. Consider the following statements:
1.The annual range of temperature is greater in the Pacific Ocean than that in the Atlantic Ocean
2.The annual range of temperature is greater in the Northern Hemisphere than that in the Southern Hemisphere.
Which of the statements given above is/are correct?
Statement 1 is incorrect. ‘The size of the oceans and the seas affects annual range of temperature e.g., bigger the size, lower the annual range and vice versa. ‘Ihe Atlantic Ocean records relatively higher annual range of temperature than the Pacific Ocean due to this reason.
Statement 2 is correct. The temperature of ocean water varies in the northern and the southern hemispheres because of dominance of land in the former and water in the latter. The oceans in the northern hemisphere receive more heat due to their contact with larger extent of land than their counterparts in the southern hemisphere and thus the temperature of surface water is comparatively higher in the former than the latter.
Other factors affecting the distribution of temperature of ocean water include:
Latitudes: “The temperature of surface water decreases from equator towards the poles because the sun’s rays become more and more slanting and thus the amount of insolation decreases poleward accordingly.
Prevailing wind: Wind direction largely affects the distribution of temperature of ocean water. The winds blowing from the land towards the oceans and seas (e.g., offshore winds) drive warm surface water away from the coast resulting into upwelling of cold bottom water from below.
Ocean currents: Surface temperatures of the oceans are controlled by warm and cold currents. Warm currents raise the temperature of the affected areas whereas cool currents lower down the temperature. For example, the Gulf Stream raises the temperature near the eastern coasts of N. America and the western coasts of Europe.
#99. Between India and East Asia, the navigation-time and distance can be greatly reduced by which of the following?
1. Deepening the Malacca straits between Malaysia and Indonesia.
2. Opening a new canal across the Kra isthmus between the Gulf of Siam and Andaman Sea.
Which of the statements given above is/are correct?
Statement 1 is incorrect. Ihe current depth of Strait of Malacca is 25 metres, which prohibits entry of some of the biggest ships in the world. However, deepening it will not reduce navigation-time and distance to be travelled.
Statement 2 is correct. The Kra Isthmus is the narrowest part of the Malay Peninsula. Kra canal is a proposed canal which would reduce the travel time by eliminating need of going around the Malay peninsula, and reducing a distance of nearly 1,200 kilometres.
#100. La Nina is suspected to have caused recent floods in Australia. How is La Nina different from El Nino?
1. La Nina is characterised by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterised by unusually warm ocean temperature in the equatorial Pacific Ocean.
2. El Nino has adverse e ect on south-west monsoon of India, but La Nina has no effect on monsoon climate.
Which of the statements given above is/are correct?
Statement 1 is incorrect. La Nina is characterised by unusually cold ocean temperatures in the Equatorial Pacific compared to El Nino Whereas El Nino is characterized by unusually warm ocean temperatures in the Equatorial Pacific.
Statement 2 is incorrect. La Nina is favourable to Indian monsoon whereas, El Nino has adverse effect on south- west monsoon.
#101. Consider the following factors:
1. Rotation of the Earth
2. Air pressure and wind
3. Density of ocean water
4. Revolution of the Earth
Which of the above factors influence the ocean currents?
Option 1 is correct. Rotation of Earth leads to Coriolis effect which influences direction of ocean currents. The Coriolis effect causes air and water to move towards the right in the northern hemisphere and the left in the southern hemisphere.
Option 2 is correct. Wind is the primary force driving surface currents in the ocean. Warm air masses form where the sun’s radiation is most intense, which is at the equator, this becomes an area of low pressure. Cold air masses form at the poles, where the sun’s radiation is less intense, this becomes an area of high pressure. Rising warm air travels from low pressure to high pressure, resulting in wind. “The dominant wind patterns drive oceanic currents.
Option 3 is correct. The density of ocean water influences the speed of the ocean currents. Also, denser water tends to sink, while relatively lighter water tends to rise.
Option 4 is incorrect. Revolution of Earth does not influence the movement of Ocean Currents. Insolation, Planetary winds, Gravity, Salinity of ocean water, Shape of coastline are some other important factors which influence the movement of ocean currents.
#102. The most important fishing grounds of the world are found in the regions where
The meeting of the cold and warm water, on the other hand, produces favourable conditions for the growth of plankton, on which fish depend directly or indirectly for their food supply. Thus, the areas where warm and cold currents meet are the best fishing grounds in the world. For instance, Grand Banks in North America is an international fishing ground where the cold Labrador Current and the relatively warm Gulf Stream.
#103. e annual range of temperature in the interior of the continents is high as compared to coastal areas. What is / are the reason / reasons?
1. Thermal difference between land and water
2. Variation in altitude between continents and oceans
3. Presence of strong winds in the interior
4. Heavy rains in the interior as compared to coasts
Select the correct answer using the codes given below.
Statement 1 is correct. The continents get heated faster and get cooled faster in comparison to the Oceans. The annual range of temperature is high in the interior of the continent because places located in the interior of the continent are far away from the moderating influence of the sea.
Statements 2 is incorrect. Altitude affects the daily range of temperature and annual mean temperature but has negligible impact on annual range of temperature. Latitude affects the annual range of temperature. The annual range of temperature increases with increasing latitude.
Statement 3 is incorrect. Wind are generally stronger near the coasts compared to interior areas of continents.
Statement 4 is incorrect. Rainfall in the interiors of the Continents is generally low as compared to Coasts. It is because the rain bearing winds from seas and oceans tend to loss most of the moisture till they reach the interiors.
#104. Which of the following have coral reefs?
1. Andaman and Nicobar Islands
2. Gulf of Kachchh
3. Gulf of Mannar
4. Sunderbans
Select the correct answer using the code given below.
Option 1, 2 and 3 are correct. Coral reefs ideally require sunlight, clean water to sunlight through, Salt water, and abundant Planktons. In India, the major reef formations are found in the Gulf of Mannar, Palk bay, Gulf of Kutch, Andaman and Nicobar Islands and the Lakshadweep islands.
Option 4 is incorrect. Due to the presence of high volume of freshwater, coral reefs are not formed in Sunderbans.

1. Bangkok
2. Hanoi
3. Jakarta

The sequence of the given cities from South to North is Jakarta, Singapore, Bangkok and Hanoi.
#107. Tides occur in the oceans and seas due to which among the following?
1. Gravitational force of the Sun
2. Gravitational force of the Moon
3. Centrifugal force of the Earth
Select the correct answer using the code given below.
Statement 1 and 2 are correct. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the moon and the sun, and the rotation of the earth.
Statement 3 is correct. Tides occur due to an imbalance between the various forces acting on the ocean water at a point in time. In general, the tide-generating force is the difference between these two forces; i.e. the gravitational attraction due to the mass of the moon and the centrifugal force due to rotation of the earth. Together, the gravitational pull and the centrifugal force are responsible for creating the two major tidal bulges on the earth. On the side of the earth facing the moon, a tidal bulge occurs while on the opposite side though the gravitational attraction of the moon is less as it is farther away, the centrifugal force causes tidal bulge on the other side.
