How is a concentration gradient related to the process of diffusion?

Molecules diffuse from areas of high concentration, to areas of low concentration, down a concentration gradient.

The concentration gradient therefore represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient.

Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached.
