Saturation, or being soaked, refers to a state where a material, such as soil or fabric, has absorbed the maximum amount of liquid it can hold. When a substance is saturated, any additional liquid will not be absorbed and may instead pool on the surface. This concept is commonly observed in various contexts, including gardening, where saturated soil can affect plant health. In meteorology, saturation occurs when the air reaches its maximum capacity for moisture, leading to conditions like fog or rain. This is often measured using relative humidity, which indicates how close the air is to being fully saturated. Understanding saturation is essential in fields like agriculture and weather forecasting.
