A logarithmic or growth spiral is a special kind of spiral curve. You can distinguish a logarithmic spiral from an Archimedean spiral, because the distances between the turnings of a logarithmic spiral keep increasing, while the distances in an Archimedean spiral are constant. Logarithmic spirals often occur in nature. Select two of the following and explain, using approximate numbers, how the spiral might be logarithmic.

The approach of a hawk to its prey. As the hawk descends, its best view is at an angle to its flight path; this angle is the same as the spiral's pitch.
