nedvességciklus

The nedvességciklus, or water cycle, describes the continuous movement of water on, above, and below the surface of the Earth. This essential process involves several key stages. Evaporation is the transformation of liquid water into water vapor, primarily driven by solar energy. Transpiration, a similar process, occurs when plants release water vapor into the atmosphere through their leaves. As this water vapor rises into the atmosphere, it cools and condenses, forming clouds. This stage is called condensation. When these clouds become saturated, precipitation occurs, releasing water back to the Earth's surface in the form of rain, snow, sleet, or hail. Once on the ground, water can follow several paths. It can flow over the land as surface runoff, eventually reaching rivers, lakes, and oceans. Alternatively, it can infiltrate the soil, becoming groundwater. This groundwater can be stored in underground aquifers or slowly move towards surface water bodies. The water cycle is a closed system, meaning the total amount of water on Earth remains relatively constant, constantly changing its form and location.
