1. Consider the following statements regarding the United Nations Human Settlements Programme (UN-Habitat):
- It is mandated by the United Nations General Assembly to promote socially and environmentally sustainable towns and cities with the objective of providing adequate shelter for all.
- It was established in 1978 as an outcome of the Habitat I Conference held in Vancouver, Canada in 1976.
- The mandate of UN-Habitat derives solely from the Habitat Agenda adopted in Istanbul in 1996.
Which of the above statements is / are correct?
[A] Only 1 and 2
[B] 1 and 2 only
[C] 2 and 3 only
[D] All are correct
Show Answer
Correct Answer: B [1 and 2 only]
Notes:
Statements 1 and 2 are correct: UN-Habitat is mandated by the UN General Assembly to promote sustainable cities and was established in 1978 as an outcome of Habitat I in 1976. Statement 3 is incorrect because the mandate of UN-Habitat does not derive solely from the Habitat Agenda; it was established prior to the 1996 Istanbul conference.
2. Consider the following statements:
- Hotspot volcanism is a type of volcanism that typically occurs at the plate margins.
- The Iceland Hotspot and Afar Hotspot are examples of hotspot volcanism.
Which of the statements given above is/are correct?
[A] Only 1
[B] Only 2
[C] Both 1 and 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: B [Only 2]
Notes:
Hotspot volcanism generally occurs within the interior of tectonic plates, not at plate margins. The Iceland Hotspot and Afar Hotspot, though situated on divergent boundaries, are valid examples of hotspot volcanism and represent exceptions. Other well-known hotspots include the Hawaiian, Yellowstone, and Reunion Hotspots, illustrating anomalous volcanism away from plate boundaries.
3. Consider the following statements:
- Aseismic ridges are formed by a hotspot in the mantle under the Earth's crust.
- A mantle plume is the convection of abnormally hot rock within the Earth's mantle.
- The position of the mantle plumes keeps on changing.
Which of the above statements is/are correct?
[A] Only 1 and 2
[B] Only 2
[C] Only 1 and 3
[D] 1, 2 and 3
Show Answer
Correct Answer: A [Only 1 and 2]
Notes:
Statement 1 is correct as aseismic ridges are formed by hotspots beneath the Earth's crust. Statement 2 is correct as mantle plumes involve convection, not conduction, of abnormally hot rock. Statement 3 is incorrect because mantle plumes are generally fixed in position, unlike larger convection cells that change over geological timescales.
