1. Consider the following statements regarding west flowing rivers in India:
- These rivers do not form estuaries.
- These rivers do not form distributaries.
- These rivers do not form deltas.
Which of the above statements is / are correct?
[A] Only 1 and 2
[B] Only 1 and 3
[C] Only 3
[D] Only 2 and 3
Show Answer
Correct Answer: D [Only 2 and 3]
Notes:
The major west flowing rivers of India, such as the Narmada and Tapi, generally flow through hard rocks and do not carry much silt. As a result, they do not form distributaries or deltas; instead, they form estuaries before entering the Arabian Sea. Thus, statements 2 and 3 are correct, whereas statement 1 is incorrect.
2. Consider the following conditions required for a planet to be considered habitable:
- Absence of a magnetic field
- Location outside the Goldilocks Zone
- Ability to retain an atmosphere
- Presence of liquid water
Which of the above conditions are essential for planetary habitability?
[A] Only 3 and 4
[B] 1, 3 and 4
[C] 2, 3 and 4
[D] 1, 2, 3 and 4
Show Answer
Correct Answer: A [Only 3 and 4]
Notes:
For a planet to be habitable, it must possess the ability to retain an atmosphere (to support life processes and regulate temperature) and have liquid water. The absence of a magnetic field and location outside the Goldilocks Zone make a planet inhospitable, as magnetic fields protect atmospheres and the Goldilocks zone ensures suitable temperatures for liquid water.
