QJEEM23Ph6041: JEE Main 2023 Physics - Class 12 JEEM23Ph6041 Solution: Match List - I with List - II .tg…

Let's match the layers of the atmosphere (List - I) with their approximate heights over the Earth's surface (List - II):

(A) $\mathrm{F_1}$ - Layer: This layer is part of the ionosphere, which is located within the thermosphere. The $\mathrm{F_1}$ layer is at an approximate height of 170 - 190 km. So, A matches with II.

(B) $\mathrm{D}$ - Layer: This layer is also part of the ionosphere and is the lowest layer of the ionosphere. The $\mathrm{D}$ layer is at an approximate height of 65 - 75 km. So, B matches with IV.

(C) Troposphere: This is the lowest layer of the Earth's atmosphere, where weather occurs, and it extends up to approximately 10 km over the Earth's surface. So, C matches with I.

(D) $\mathrm{E}$ - Layer: This layer is another part of the ionosphere, which is above the $\mathrm{D}$ layer and below the $\mathrm{F_1}$ layer. The $\mathrm{E}$ layer is at an approximate height of 100 km. So, D matches with III.

Thus, the correct matching is:

A - II, B - IV, C - I, D - III
