Which type of ocean floor sediment is biological in origin?
Biogenous
The thickest sedimentary deposits are found?
The thickest sedimentary deposits are typically found in basins and troughs where large amounts of sediment have accumulated over millions of years. These areas can include deep ocean basins, continental rift zones, and areas where rivers deposit sediment such as deltas. The sediment can accumulate to great thickness due to tectonic activity, climate changes, or the presence of large amounts of sediment sources.
Ooze on the ocean floor is formed from the remains of which of these?
Ooze on the ocean floor is formed from the remains of marine organisms like phytoplankton and zooplankton, as well as shells and skeletons of marine animals. Over time, these organic materials accumulate and form sediment on the ocean floor.
Deep ocean sediments are thickest where the underlying crust is?
oldest and has accumulated over millions of years. The thickness of the sediments can vary depending on factors such as tectonic activity, sediment supply, and water depth.
Flat seafloor in the deep ocean formed when deposits of sediment filled valleys?
Flat seafloor in the deep ocean, known as abyssal plains, is formed over time as sediment accumulates in the valleys and depressions of the ocean floor. This sediment is often carried by underwater currents and deposited in these low-lying areas, creating a smooth and flat seafloor surface.
