An abyssal plain is a flat, deep-sea floor found at depths of about 3,000 to 6,000 meters. These vast underwater landscapes cover more than 50% of the Earth's surface and are often found between the continental slopes and mid-ocean ridges. The plains are formed by the accumulation of sediments, such as mud and tiny marine organisms, which settle over time.
Despite their depth, abyssal plains are home to unique ecosystems. Creatures like deep-sea fish, sea cucumbers, and bacteria thrive in these dark, cold environments. Scientists study these areas to understand more about ocean life and the Earth's geological processes.
