1. How big is Hydrology?Surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology
2. What is the etymological origin?Derived from Ancient Greek 'húdōr' (water) and '-logía' (study of)
3. What is the key applications?Water resource management, flood and drought mitigation, environmental preservation, and infrastructure planning
4. How do hydrologists study water?They use tools like satellites, weather stations, and stream gauges to measure rain, river flow, and underground water.
5. Why is the hydrologic cycle important?It shows how water evaporates, forms clouds, falls as rain, and flows back to oceans, helping us know where water will be and how to protect it.

Hydrologic Cycle: The continuous circulation of water on, above, and below the surface of the Earth, involving evaporation, condensation, precipitation, and runoff.
Hydrogeology: The branch of hydrology concerned with the occurrence, movement, and quality of groundwater.
Drainage Basin: A geographical area where all surface water converges to a single point, such as a river mouth or a lake.
Evapotranspiration: The combined process of evaporation from the Earth's surface and transpiration from plants into the atmosphere.
