Question 1 of 5
1. Question
Consider the following statements regarding Siachen Glacier.
- The Siachen Glacier is located in the Karakoram range in the Western Himalayas.
- The glacier is the source of Nubra River, which is a tributary of Shyok river.
- The region is home to rare species including snow leopard, brown bear and ibex.
Which of the above statements is/are correct?
Correct
Solution: d)
Siachen glacier lies in the Karakoram Range system which is a part of western Himalayas.
Lies to the south of the zone that separates Eurasion Plate with the Indian Plate, which is the result of convergence boundary interaction in geographical terms.
The glacier is the source of many rivers including Nubra River, a tributary of Shyok, which is a part of the Indus River System.
The region is also a home to rare species of snow leopard, brown bear etc which may be affected by military presence. This has led to talks in international forums about creating a “Peace Park” in the area and demilitarise it.

Question 3 of 5
3. Question
Sea water temperature is relatively higher in northern hemisphere as compared to southern hemisphere, because
Correct
Solution: b)
The temperature of ocean water varies in the northern and the southern hemispheres because of dominance of land in the northern hemisphere and water in the southern hemisphere.
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 northern hemisphere than the southern hemisphere.

Question 5 of 5
5. Question
Consider the following statements about ocean salinity.
- In oceans, sodium chloride alone constitutes 95% of ocean salts.
- The salinity of water in the surface layer of oceans depend both on evaporation and precipitation.
- Ocean currents do not cause salinity variations.
Which of the above statements is/are correct?
Correct
Solution: b)
Factors affecting ocean salinity are mentioned below:
- The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation.
- Surface salinity is greatly influenced in coastal regions by the fresh water flow from rivers, and in polar regions by the processes of freezing and thawing of ice.
- Wind, also influences salinity of an area by transferring water to other areas.
- The ocean currents contribute to the salinity variations. Salinity, temperature and density of water are interrelated. Hence, any change in the temperature or density influences the salinity of water in an area.
- Sodium chloride constitutes around 77.7% of ocean salts.
