The study of all water on Earth, including its movement and distribution?

• A. Hydrology
• B. Ozone layer
• C. Hydrosphere
• D. Barometer

Answer: (A)

Hydrology is the science that studies all water on Earth, including how it moves and how it is distributed across oceans, land, and the atmosphere. It covers the water cycle—precipitation, evaporation, condensation, infiltration, and runoff—and follows water through rivers, lakes, groundwater, and the oceans. The ozone layer is a region of the atmosphere concerned with ozone, not water. The hydrosphere is the body of water on Earth itself, not the study of it. A barometer measures atmospheric pressure, not water movement.
