The water surface is the upper layer of a body of water, such as a lake, river, or ocean. It is where the water meets the air, creating a boundary that can be affected by various factors like wind, temperature, and the presence of objects. The surface tension of water allows small objects, like water striders, to float without sinking. The water surface plays a crucial role in the environment. It is involved in processes like evaporation, which contributes to the water cycle, and it supports ecosystems by providing habitats for aquatic life. Additionally, the surface can reflect light, creating beautiful visual effects, especially during sunrise and sunset.
