Since the oceans cover large parts of the Earth, they have important effects on the biosphere. Evaporation of ocean water (as a member of the water cycle) plays an important role in creating rainfall, and in fact, ocean temperature is one of the most important keys to climate change on Earth. The age of the oceans is estimated to be about 3 billion years, and it was then that plants and living creatures appeared on it. The edge of the oceans is home to different species of aquatic animals and plants, and the important part of the oceans are located far from the coasts, which determine the type of ecosystems on the land surface of the earth.🌏🌎🌍
