Sediment piles up on the ocean floor is what process?

The accumulation of sediment on the ocean floor is primarily the result of sedimentation, a process where particles settle out of water due to gravity. This can occur through various mechanisms, including the deposition of materials eroded from land, the remains of marine organisms, and chemical precipitation. Over time, these sediments build up in layers, contributing to the formation of sedimentary rocks and influencing ocean floor topography.
