A flash flood differs from a normal flood
ABy a sudden increase in the level of water
BAs it is likely to cause much more damage
CBoth (a) and (b) ✓ Correct
DNone of the above
Correct answer: (C) Both (a) and (b)
Explanation
A flash flood differs from a normal flood both by the sudden rise in water level and by its greater damage potential.
The sudden rise alone is only half the distinction, since severity of damage also sets it apart.
The greater damage alone is incomplete, since the abrupt speed of onset is its defining trait.
Since both features apply together, none of the above does not fit.
Flash floods often follow cloudbursts or dam bursts, leaving little warning time.
Their rapid, forceful flow makes escape and rescue much harder.
