The correct answer is C. both (a) and (b).
The hydrological cycle is a conceptual model that describes the movement of water on, above and below the Earth’s surface. It is a closed system, meaning that the total amount of water on Earth does not change, but it is constantly being recycled.
The water cycle is driven by the sun’s energy. The sun heats the Earth’s surface, causing water to evaporate from the oceans, lakes, rivers and soil. This water vapor rises into the atmosphere, where it cools and condenses into clouds. The clouds release the water back to the Earth as precipitation, in the form of rain, snow, sleet or hail. The water then flows back into the oceans, lakes, rivers and soil, or it is absorbed by plants.
The hydrological cycle is essential for life on Earth. It provides us with fresh water, regulates the Earth’s temperature and helps to distribute nutrients around the globe.
Option A is incorrect because it only describes the storage of water. Option B is incorrect because it only describes the movement of water. Option D is incorrect because it is not a valid option.
