A temperature gradient refers to the change in temperature over a specific distance in a given area. It can occur in various environments, such as in the atmosphere, oceans, or even within solid materials. For example, when you move from a warm room to a cold hallway, you experience a temperature gradient as the temperature decreases. Temperature gradients are important in many scientific fields, including meteorology and oceanography. They can influence weather patterns, ocean currents, and even the behavior of animals and plants. Understanding these gradients helps scientists predict changes in the environment and how different systems interact.
