The significance of the water cycle lies in its role in maintaining the Earth's ecosystems and supporting life. It describes the continuous process of water movement through the environment, encompassing evaporation, condensation, precipitation, and infiltration. This cycle contributes to regulating climate, replenishing groundwater supplies, and sustaining habitats. Moreover, the water cycle is essential for the distribution of nutrients and energy within ecosystems, impacting agriculture, wildlife, and human activities. Understanding the water cycle is crucial for managing water resources and addressing issues like climate change.
