Lakes are large bodies of freshwater or saltwater surrounded by land. They can be formed through various natural processes, such as glacial activity, tectonic movements, or volcanic eruptions. Lakes provide habitats for diverse wildlife and are often used for recreational activities like fishing, boating, and swimming. Lagoons are shallow bodies of water separated from larger bodies of water, such as oceans or seas, by a barrier like a sandbar or coral reef. They are typically found along coastlines and can be brackish, containing a mix of freshwater and saltwater. Lagoons support unique ecosystems and are important for coastal protection and biodiversity.
