moisture
Definition
Moisture is the presence of water in the air or on a surface. It can be measured in terms of the amount of water vapor in the air, or the amount of water that is absorbed by a material.
Moisture is important for many different processes, including:
- Plant growth: Plants need moisture to absorb nutrients from the soil and to transport water and nutrients throughout their bodies.
- Animal survival: Animals need moisture to stay hydrated and to regulate their body temperature.
- Weather: Moisture in the air can form clouds, rain, snow, and ice.
- Industry: Moisture is used in many industrial processes, such as papermaking, textiles, and food processing.
Moisture can be a problem in some cases, such as when it causes corrosion or mould growth. However, it is also essential for many important processes.
How can the word be used?
The leaves on the trees were covered in moisture from the morning dew.
Different forms of the word
Noun: Water vapour in the air or on a surface.
Adjective: Damp or wet.
Verb: To make something damp or wet.
Etymology
The word "moisture" comes from the Old French word "moiste," which means "damp" or "wet." The Old French word "moiste" is derived from the Latin word "mŭscus," which also means "damp" or "wet.".
The word "moisture" was first used in English in the 13th century. It originally had a more literal meaning, referring to water vapor in the air or on a surface. However, the meaning of the word has expanded over time to include any type of dampness or wetness.

AQA Science Exam Question and Answer
Question:
Explain the concept of moisture and its significance in both the natural environment and human activities. Provide examples of how moisture levels impact different aspects of our lives and the environment.
Answer:
Moisture refers to the presence of water vapour in the air or the state of being damp or wet. It plays a significant role in both the natural world and human activities.
In the natural environment, moisture levels influence various phenomena. Humidity, a measure of moisture content in the air, affects weather patterns and the formation of clouds and precipitation. Moisture also influences the growth and health of plants, as it affects soil moisture and plant transpiration rates. For instance, areas with high moisture levels often have lush vegetation due to optimal conditions for plant growth.
In human activities, moisture control is essential in multiple aspects. In construction, maintaining appropriate moisture levels prevents mould growth and structural damage. Food preservation relies on regulating moisture to prevent spoilage and maintain product quality. Moisture also affects comfort levels in indoor spaces; high humidity can make environments feel hotter and discomforting.
In agricultural practices, monitoring soil moisture helps farmers optimise irrigation, leading to efficient water use and increased crop yields. Moisture detection techniques are employed in industries like textiles and electronics to ensure product quality and performance.
