Vedclass · Answer

(A) The atmospheric layers and their approximate heights are as follows:$1$. The $F_1$-layer of the ionosphere is located at an approximate height of $170-190\,km$.$2$. The $D$-layer of the ionosphere is located at an approximate height of $65-75\,km$.$3$. The Troposphere is the lowest layer of the atmosphere,extending up to approximately $10\,km$ from the Earth's surface.$4$. The $E$-layer of the ionosphere is located at an approximate height of $100\,km$.Matching these values:$(A) \rightarrow (II)$$(B) \rightarrow (IV)$$(C) \rightarrow (I)$$(D) \rightarrow (III)$Therefore,the correct sequence is $(A)-(II), (B)-(IV), (C)-(I), (D)-(III)$.

List-$I$ (Layer of atmosphere)	List-$II$ (Approximate height over earth's surface)
$(A)$ $F_1$-Layer	$(I)$ $10\,km$
$(B)$ $D$-Layer	$(II)$ $170-190\,km$
$(C)$ Troposphere	$(III)$ $100\,km$
$(D)$ $E$-Layer	$(IV)$ $65-75\,km$
