What is a logarithmic spiral? How is it different from Archimedean spiral?

In an Archimedean spiral, the distances of intersection points along a line that goes through the origin of the spiral are constant. An illustration of an Archimedean spiral follows:

Whereas in a logarithmic spiral, the distances of intersection points along a line that goes through the origin of the spiral are growing exponentially. An illustration of a logarithmic follows:
