Question 1 of 5
1. Question
Consider the following statements regarding the vertical distribution of Salinity.
- Salinity at the surface decreases by the loss of water to ice.
- Salinity at depth is very much fixed, because there is no way that water is lost, or the salt is added.
- Halocline is a distinct zone where salinity increases sharply.
Which of the above statements is/are correct?
Correct
Solution: c)
Salinity changes with depth, but the way it changes depends upon the location of the sea. Salinity at the surface increases by the loss of water to ice or evaporation, or decreased by the input of fresh waters, such as from the rivers. Salinity at depth is very much fixed, because there is no way that water is ‘lost’, or the salt is ‘added.’ There is a marked difference in the salinity between the surface zones and the deep zones of the oceans. The lower salinity water rests above the higher salinity dense water. Salinity, generally, increases with depth and there is a distinct zone called the halocline, where salinity increases sharply.

Question 2 of 5
2. Question
With reference to river Teesta, consider the following statements:
- The source of river Teesta is the same as that of Brahmaputra but it flows through Sikkim.
- River Rangeet originates in Sikkim and it is a tributary of river Teesta.
- River Teesta flows into Bay of Bengal on the border of India and Bangladesh.
Which of the above statements is/are correct?
Correct
Solution: b)
Teesta River originates from the Pahunri glacier. Brahmaputra originates in Angsi glacier. Teesta is a tributary of Brahmaputra. But, Teesta flows through West Bengal and Sikkim, before going to Bay of Bengal through Bangladesh. Rangeet is a tributary of the Teesta River, which is the largest river in Sikkim. It also originates in Sikkim.

Question 3 of 5
3. Question
Consider the following statements about Earthquake.
- All natural earthquakes take place in the lithosphere.
- The denser the material, the lower is the velocity of the earthquake waves.
- The surface waves are more destructive.
Which of the above statements is/are correct?
Correct
Solution: c)
All natural earthquakes take place in the lithosphere. Earthquake waves are basically of two types — body waves and surface waves. Body waves are generated due to the release of energy at the focus and move in all directions travelling through the body of the earth. The body waves interact with the surface rocks and generate new set of waves called surface waves. These waves move along the surface. The velocity of waves changes as they travel through materials with different densities. The denser the material, the higher is the velocity. The surface waves are the last to report on seismograph. These waves are more destructive. They cause displacement of rocks, and hence, the collapse of structures occurs.

Question 5 of 5
5. Question
Consider the following statements:
- River Jhelum forms Meanders even in the youth stage of river development.
- River Jhelum forms a natural boundary between India and Pakistan.
- Lake Wular is situated on the river Jhelum.
Which of the above statements is/are correct?
Correct
Solution: c)
Jhelum in the valley of Kashmir is still in its youth stage and yet forms meanders – a typical feature associated with the mature stage in the evolution of fluvial land form. River Jhelum forms a natural boundary between India and Pakistan. Lake Wular is situated on the river Jhelum.
