WebA glib answer is that "gradient" is a vector and "divergence" is a scalar. More specifically (and perhaps helpfully), the gradient vector points in the direction of the fastest (local) increase in the value of the (scalar) function. The divergence (of a vector field) provides a measure of how much "flux" (or flow) is passing through a surface ...
