- The positive loop or the feedback may be that the pond reaction to the chemicals thus becoming more of acidic as a result of pollution
- For example, the polar ice caps form a positive loop by the increase in greenhouse gases the melt is induced due to the spread effects and that is a universal phenomenon.

The asteroid belt is too hot for comets to form.
Explanation:
Asteroids are made up of metals and rocky materials, while comets are basically ice, dust, few rocky materials and some organic compounds. Short period comets are formed in the Kuiper belt, and long period comets originate from the outer regions of the solar system. Short period comets orbit the sun completely in less than 200 years. Since they are mostly ice and dust, they cannot be formed in the asteroid belt.
