Are electric fields produced by static electric charges different from those produced by time-varying magnetic fields? I came across an interesting yet perplexing statement in my physics textbook:

However, we hasten to add that electric fields produced by static electric charges have properties different from those produced by time-varying magnetic fields.

My questions are, simply put:
What exactly are these properties? And why do they differ?
 A: The only difference is in the structure of the fields:


*

*The field contribution from static charges are non-rotational (curl-free) but divergent.

*The field contributions from time-varying magnetic fields are divergence-less but have non-zero curl.
You can read this right out of the Gauss and Faraday's Laws in their differential form:
\begin{align*}
\mathbf{\nabla \cdot E} &= \frac{\rho}{\epsilon_0} \\
\\
\mathbf{\nabla \times E} &= - \frac{\partial \mathbf{B}}{\partial t} \;.
\end{align*}
The operators on the LHSs are called "divergence" and "curl" (read top to bottom).

I hasten to add that these are exactly the same kind of stuff, which is why I've written "contributions from" rather than "fields produced by" as if the fields might be of different kinds. In the presence of both static charges and varying magnetic field the total electric field will show both divergence and curl.
