At which latitude, heat gain through insolation approximately equals heat loss through terrestrial radiation ?
66\(\degree\) North and South
22\(\bigg(\frac{1}{2}\bigg)\degree\) North and South
40\(\degree\) North and South
42\(\bigg(\frac{1}{2}\bigg)\degree\) North and South
The Correct Option is A
Solution and Explanation
The latitude at which heat gain through insolation approximately equals heat loss through terrestrial radiation is at 66\(\degree\) North and South.
At these latitudes, near the poles, there is a balance between the heat received from the Sun (insolation) during the day and the heat radiated away from the Earth's surface during the night, resulting in a relatively stable temperature regime. This is one of the factors contributing to the formation of the polar climates.
So, the correct option is (A): 66\(\degree\) North and South

- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - A wire of resistance \(R\) is cut into 8 equal pieces. From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

Conservation of Biodiversity
The protection, preservation, and management of ecosystems and natural habitats refers to biodiversity conservation and ensuring that they are healthy and functional.
The protection, upliftment, and scientific management of biodiversity refer to the conservation of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation.
The following are the three main objectives of Biodiversity Conservation-
- To protect and preserve species diversity.
- Ensuring sustainable management of the species and ecosystems.
- To prevent and restore the ecological processes and life support systems.
