1. Atmospheric water generators are used for which of the following?
[A] To produce artificial rain in rain-deficit regions
[B] To produce potable water from surrounding air
[C] For drip irrigation for sustainable agriculture
[D] For cleaning the polluted rivers
Show Answer
Correct Answer: B [To produce potable water from surrounding air]
Notes:
- Atmospheric Water Generator is being manufactured by BEL in collaboration with CSIR-IICT and MAITHRI, a start-up company based in Hyderabad.
- It employs a novel technology to extract water from the humidity present in the atmosphere and purify it.
- It uses heat exchange for condensing the atmospheric moisture to produce pure, safe and clean potable water.
- It uses technology to produce potable water from surrounding air. This provides the potential to expand water availability during shortages, contamination events, and other issues that can interrupt drinking water services.

[A] Only 3
[B] Only 1 and 3
[C] Only 2 and 3
[D] 1, 2 and 3
Show Answer
Correct Answer: D [1, 2 and 3]
Notes:
Guyots and seamounts are volcanic, rising steeply from the sea floor. A shoal is defined as a detached elevation with shallow depths, often hazardous to navigation. Reefs are mostly organic in origin, formed by accumulation of living or dead organisms such as corals and algae. Therefore, all three statements are correct as per the described oceanic and coastal landforms.

Vanuatu is a Y-shaped archipelago of 83 islands located to the north-east of Australia, not south-west. It is part of the Australasia Eco zone, and its closest neighbors are Fiji, New Caledonia, Solomon Islands, and Australia. Only statements 2 and 3 are correct, while statement 1 contains a geographical inaccuracy.
