Solution
Concept
Hydrology is the science of the occurrence, circulation and distribution of water on the earth and in its atmosphere.
Step-by-step solution
1. Read the definition: occurrence, circulation and distribution of water on earth and in the atmosphere. 2. This is the hydrologic (water) cycle. 3. The science of the water cycle is hydrology. 4. Answer: (B) hydrology.
Explanation
Hydrology studies water on land, under the ground and in the atmosphere. It covers rainfall, evaporation, infiltration, runoff and groundwater. These are all parts of the hydrologic cycle.
Why the other options are wrong
A: Hydraulics studies the mechanics of water flow in pipes and channels, not the water cycle. C: Oceanography studies only the oceans. D: Environment is a broad general term, not a specific water science.
Shortcut
'Hydro' means water and 'logy' means science, so hydrology is the science of water.
Common mistake
Confusing hydrology (water cycle) with hydraulics (flow mechanics).
Correct answer: B) hydrology
