How does the water cycle support environmental sustainability?

• A. By increasing temperature stability
• B. By recycling nutrients
• C. By ensuring water availability
• D. By regulating atmospheric pressure

Answer: (C)

The correct answer is focused on how the water cycle ensures water availability, which is vital for maintaining ecosystems and supporting life on Earth. The water cycle describes the continuous movement of water through evaporation, condensation, precipitation, and infiltration, ensuring that water moves from one part of the environment to another. This cycle replenishes freshwater sources, such as rivers, lakes, and aquifers, which are essential for drinking water, agriculture, and sustaining natural habitats. When water is consistently available through this natural process, it supports plant growth, animal life, and human activities, which are fundamental components of a sustainable environment. The availability of fresh water influences biodiversity, agricultural productivity, and even climate regulation, making it a key aspect of environmental sustainability. In contrast, while the other options relate to important environmental processes, they do not capture the primary role of the water cycle in sustaining water resources. For instance, temperature stability and atmospheric pressure are more influenced by broader climate dynamics, while the recycling of nutrients pertains to soil health rather than directly to the provision of water resources. Thus, ensuring water availability through the water cycle is a cornerstone of environmental sustainability.
