- 1. Hydrology is the study of the movement, distribution, and quality of water on Earth. It encompasses the occurrence of water in various forms such as rivers, lakes, and oceans, as well as underground aquifers. Hydrologists analyze the hydrologic cycle which includes processes like evaporation, precipitation, and runoff. Understanding hydrology is crucial for managing water resources, predicting floods, and assessing the environmental impact of human activities on water systems.

D) Precipitation
- 5. What does the term 'aquifer' refer to in hydrology?
A) An underground layer of water-bearing rock
B) A type of cloud formation
C) A rare species of fish
D) A glacier
- 6. What is the process by which water is absorbed by plant roots and released into the atmosphere called?
