Question

At which latitude, heat gain through insolation approximately equals heat loss through terrestrial radiation ?

• A. 66$\degree$ North and South
• B. 22$\bigg(\frac{1}{2}\bigg)\degree$ North and South
• C. 40$\degree$ North and South
• D. 42$\bigg(\frac{1}{2}\bigg)\degree$ North and South

Answer 1

Answer: (A)

66$\degree$ North and South

Answer 2

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
