Rivers and oceans play crucial roles in nature. Rivers transport nutrients and sediment across landscapes, provide habitats for various species, and contribute to the water cycle. Oceans cover more than 70% of the Earth's surface and are essential for regulating the planet's climate, as well as supporting a diverse array of marine life. Together, rivers and oceans are vital components of the Earth's ecosystems and are interconnected in maintaining the balance of life on our planet.
