An abyssal plain is a flat or gently sloping area of the ocean floor, typically found at depths between 3,000 to 6,000 meters (approximately 10,000 to 20,000 feet). These plains are among the Earth's most extensive and least explored environments, covering more than 50% of the Earth's surface. Abyssal plains are primarily composed of sediments, including clay, silt, and organic material that has settled from the water column above.
