Question

An earthquake of magnitude '6' on Richter scale has :-
(a) Ten times more destructive energy than an earthquake of magnitude '4'.
(b) Hundred times more destructive energy than an earthquake of magnitude '4'.
(c) Thousand times more destructive energy than an earthquake of magnitude '4'.
(d) One and half times more destructive energy than an earthquake of magnitude '4'.

Answer 1

Answer:

B. HUNDRED TIMES THAN 4

Explanation:

THIS IS BECAUSE MAGNITUDE DIFFERENCE OF 1 IS 10 TIMES DESTRUCTIVE SO FOR 2 MAGNITUDE IT WOULD BE 10×10 = 100 TIMES DESTRUCTIVE THAN 4
