A pond, a large earth depression where water collects, often has a serene, shallow depth composition to it. The ponds shallowness allows sunlight to penetrate to the bottom, which allows plants to grow. Pond plants either grow entirely underwater or partially on the surface. A minority of plants will also grow along the pond's edge. Ponds eventually turn into a large plot of soil if left untreated by intervention. Ponds will support a large variety of animal and plant life, such as birds, crayfish, small fish, frogs, insects, turtles, protozoa, algae, and lily pads. Ponds usually regulate the same water temperature ranging from the water's surface to the bottom. Ponds may freeze solid in colder climates.
