Question

Match the LIST-I with LIST-II. \[ \begin{array}{|c|l|c|l|} \hline LIST-I & (Orogenies) & LIST-II & (Examples) \hline A. & \text{Pre-Cambrian} & I. & \text{Scandinavia} \hline B. & \text{Caledonian} & II. & \text{Laurentian mountains} \hline C. & \text{Hercynian} & III. & \text{Rockies} \hline D. & \text{Alpine} & IV. & \text{Black Forest} \hline \end{array} \] Choose the correct answer from the options given below:

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

Hint:

Major Orogenies: \[ \boxed{ \begin{aligned} \text{Pre-Cambrian} &\rightarrow \text{Laurentian Mountains}, \text{Caledonian} &\rightarrow \text{Scandinavia}, \text{Hercynian} &\rightarrow \text{Black Forest}, \text{Alpine} &\rightarrow \text{Rockies}. \end{aligned} } \] Mnemonic: “Pre--Laurentian, Caledonian--Scandinavia, Hercynian--Black Forest, Alpine--Rockies.”

Answer 1

The Correct Option is A

Concept: Major mountain-building (orogenic) periods are associated with characteristic mountain systems across the world.

Step 1: Match each orogeny with its example. \[ \boxed{ \begin{aligned} \text{Pre-Cambrian} &\rightarrow \text{Laurentian Mountains}, \text{Caledonian} &\rightarrow \text{Scandinavia}, \text{Hercynian} &\rightarrow \text{Black Forest}, \text{Alpine} &\rightarrow \text{Rockies}. \end{aligned} } \]

Step 2: Convert into the given matching. \[ \boxed{ A\!-\!II,\; B\!-\!I,\; C\!-\!IV,\; D\!-\!III } \] Hence, \[ \boxed{\text{(A)}} \]
