Marine regions are large areas of the ocean that are classified based on their unique environmental characteristics, such as temperature, salinity, and biological diversity. These regions include the Atlantic Ocean, Pacific Ocean, Indian Ocean, and various seas and coastal areas. Each marine region supports distinct ecosystems, which are home to a variety of marine life, including fish, mammals, and coral reefs. The classification of marine regions helps scientists and conservationists understand and protect these vital ecosystems. By studying the differences between regions, researchers can identify patterns in marine biodiversity and the impacts of human activities, such as overfishing and pollution, on ocean health.
