The question asks for the year when Indira Point, the southernmost tip of India, was submerged under water. This is a factual question related to a significant geographical event.
Correct Option: C) 2004
The question asks for the percentage of fresh water available on Earth. This is a factual question related to Earth's water resources, a common topic in general knowledge and environmental science sections of competitive exams.
Correct Option: A) 2.70% is the approximate percentage of fresh water on Earth. This is a widely accepted figure in geography and environmental studies.
The question asks about the approximate contribution of a specific power source to India's total electricity production. We need to identify which power source accounts for roughly 22% of the total electricity generated in India.
Correct Option: B) Hydro electric power contributes a significant portion to India's electricity production. While its generation share is typically around 10-12% in recent years, its installed capacity is around 12-13% of the total. However, among the given options, and considering that percentages can fluctuate or refer to specific contexts (e.g., installed capacity vs. actual generation, or older data), hydroelectric power is the most fitting answer for a contribution of approximately 22% when compared to the other options which are either much higher (thermal) or much lower (solar, wind).
Around 2010–11, hydroelectric power accounted for approximately ______ per cent of India’s total installed electricity generation capacity.
The question asks about the approximate percentage of hydroelectric power in India's total installed electricity generation capacity around 2010–11. To answer this, one needs to recall or estimate the composition of India's power generation mix during that specific period.
Correct Option: C) 22%
Around 2010–11, hydroelectric power accounted for approximately 22% of India’s total installed electricity generation capacity. This figure is consistent with official statistics for that period, where hydroelectric capacity was roughly 37 GW out of a total installed capacity of about 173 GW.
The question asks for the primary reason behind the eastward flow of the equatorial counter-current. This phenomenon is a key aspect of oceanography, driven by specific interactions of wind, water movement, and pressure gradients in the equatorial regions.
B) Convergence of the two equatorial currents. This convergence leads to a piling up of water in the western part of the ocean basin, creating an eastward pressure gradient that drives the equatorial counter-current.
The question asks to identify the member countries of the 'Arctic Council' from the given list. To answer this, one needs to know the permanent members of the Arctic Council.
D) 1, 3 and 5 — This option correctly identifies Denmark, Russian Federation, and United States of America as members of the Arctic Council.
