This question was previously asked in
UPSC CAPF – 2009
The correct option is D (difference between high and low tide).
– Tidal range is defined as the vertical difference between the sea level at high tide and the sea level at the subsequent low tide in a specific location.
– Statement A describes the flood tide.
– Statement B describes the ebb tide.
– Statement C describes the phenomenon of tides itself (the periodic rise and fall of sea water).
– Statement D accurately defines the tidal range.
Tidal ranges vary significantly depending on location, due to factors such as the shape of the coastline, water depth, and oceanic currents. Places like the Bay of Fundy in Canada have very high tidal ranges, while enclosed seas like the Mediterranean have very low ones.
