Question

Match List-I with List-II.

List-I	List-II
A. Less than 3.5 B. Between 3.5 and 5.4 C. Between 5.4 and 6 D. Greater than 8	I. Very significant earthquake, cause serious damage II. Usually felt, but cause minimal damage III. Usually not felt but recorded by seismology labs IV. Can cause damage to poorly built structures over a small region

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

Hint:

On the Richter scale, low magnitudes may only be recorded by instruments, while magnitudes greater than 8 can cause serious and widespread damage.

Answer 1

The Correct Option is B

Concept: The Richter scale measures earthquake magnitude. As the magnitude increases, the earthquake effect and damage potential also increase.

Step 1: Match magnitude less than 3.5.
Earthquakes less than 3.5 are usually not felt by people, but they are recorded by seismology instruments. \[ A \rightarrow III \]

Step 2: Match magnitude between 3.5 and 5.4.
Earthquakes between 3.5 and 5.4 are usually felt, but they generally cause minimal damage. \[ B \rightarrow II \]

Step 3: Match magnitude between 5.4 and 6.
Earthquakes between 5.4 and 6 can damage poorly built structures over a small region. \[ C \rightarrow IV \]

Step 4: Match magnitude greater than 8.
Earthquakes greater than 8 are very significant and can cause serious damage over large areas. \[ D \rightarrow I \] Therefore, the correct matching is: \[ A-III,\ B-II,\ C-IV,\ D-I \]
