Natural bodies of water are formations created by nature, including rivers, lakes, ponds, and oceans. These bodies of water play a crucial role in the ecosystem, providing habitats for various plants and animals. They also serve as important resources for human activities, such as drinking water, agriculture, and recreation. The characteristics of natural bodies of water can vary widely. For example, rivers flow continuously, while lakes are typically larger and more stationary. Oceans cover about 71% of the Earth's surface and are vital for global weather patterns and marine biodiversity. Each type of water body contributes uniquely to the environment.
