Lakes and ponds are both bodies of freshwater, but they differ mainly in size. A lake is generally larger and deeper than a pond, often supporting a wider variety of wildlife and plant life. Lakes can be formed by natural processes like glacial activity or tectonic movements, while ponds are usually shallower and can be created by rainfall or human activities. Both lakes and ponds play important roles in the ecosystem. They provide habitats for various species, including fish, amphibians, and birds. Additionally, they help regulate local climates and can be sources of drinking water for nearby communities.
