Clouds are an important part of which cycle?

Correct answer: Water cycle

Clouds belong to the water cycle because they help move water through the atmosphere. Water from oceans, rivers, lakes, soil, and plants enters the air as vapour through evaporation and transpiration. When moist air rises and cools, the vapour condenses around tiny particles, forming cloud droplets or ice crystals. These may later join together and fall as precipitation, returning water to the land or ocean. Clouds therefore connect atmospheric moisture with rainfall and other parts of the cycle.

The correct answer is option A, the water cycle. Rock cutting, soil colour, and sound do not describe the continuous movement of water between Earth’s surface, atmosphere, and living systems. Clouds are especially associated with condensation and precipitation, although the complete water cycle also includes evaporation, transpiration, infiltration, runoff, and collection. Linking clouds with water movement makes the concept easier to remember and explains why they are important in geography.
