中洋脊, also known as the Mid-Ocean Ridge, is a continuous underwater mountain range that stretches across the world's oceans. It is formed by tectonic activity, where tectonic plates pull apart, allowing magma to rise and create new oceanic crust. This process is crucial for understanding plate tectonics and the geological activity of the Earth. The ridge is home to unique ecosystems, including hydrothermal vents that support diverse marine life. These vents release mineral-rich water, providing nutrients for organisms that thrive in extreme conditions. The study of 中洋脊 helps scientists learn more about oceanography and the origins of life on Earth.
