Quick Summary

A pond is a body of water that is typically smaller than a lake. Ponds are relatively shallow, allowing sunlight to penetrate to the bottom, which supports rooted aquatic plants. They experience significant seasonal changes in temperature, wind, and precipitation, making them a dynamic habitat.12

While natural ponds exist, the term "solar pond" refers to a human-made body of saltwater designed to collect and store solar energy for heat and power. These ponds use salt concentration to prevent heat loss through convection, trapping solar heat in the lower layers.3
