density gradients

Density gradients refer to the variation in density within a substance or system, where some areas have a higher concentration of mass than others. This concept is commonly observed in fluids, like air or water, where warmer, lighter areas rise and cooler, denser areas sink, creating movement. In the atmosphere, for example, density gradients influence weather patterns and air currents. In geology, they can inform us about the layers of the Earth. Understanding density gradients helps scientists explain phenomena in various fields, from meteorology to oceanography and earth sciences.
