What is the origin of most abyssal plain sediments?
Abyssal plain refers to the plains of the deep ocean floor (usually between 10,000 and 20,000 feet below sea level). An abyssal plain is often located between a continental shelf (the area around a large landmass that's under relatively shallow water) and a mid-ocean ridge (mountain ranges found deep at the bottom of the ocean's floor).
Answer and Explanation:
The origin of most abyssal plain sediments is erosion from the continental shelf. The ocean's currents that flow over a continental shelf will cause the sediments of the continental shelf (clay and silt) to be moved and deposited further out onto the ocean's floor in the areas of the abyssal plain.
