A temperature gradient refers to the change in temperature over a specific distance in a given medium, such as air, water, or solid materials. It indicates how temperature varies from one point to another, often measured in degrees per unit of distance, like degrees Celsius per meter. This concept is important in various fields, including meteorology, oceanography, and engineering. In nature, temperature gradients can influence weather patterns, ocean currents, and even the behavior of animals. For example, the Earth's atmosphere exhibits temperature gradients that contribute to wind formation, while ocean currents are driven by differences in water temperature across different regions. Understanding these gradients helps scientists predict environmental changes.
