Moisture refers to the presence of water in the air, soil, or on surfaces. It is an essential part of our environment, affecting everything from weather patterns to plant growth. For example, when the air is humid, it means there is a lot of moisture in the atmosphere, which can make us feel warmer and stickier. In everyday life, we encounter moisture in various forms, such as dew on grass in the morning or steam rising from a hot cup of tea. Understanding moisture helps us appreciate its role in nature and how it influences our daily activities and comfort.
