Warm surface water from the region moves towards the because of ocean circulation. As this warm water travels, it carries from the tropical regions towards higher latitudes. The water gradually as it moves towards the poles. This movement of warm water helps to reduce the difference in between the Equator and the polar regions. In the polar and higher-latitude regions, the water becomes and denser. The colder, denser water can move back towards the through deeper levels of the ocean. Thus, ocean currents play an important role in the of Earth's climate. They also transport heat and , which support marine life and ecosystems. Therefore, ocean currents are important for maintaining a suitable for life on Earth.
