Clastic sediments some quite coarse predominate on shelves and slopes.

Deeper regions of the ocean floor tend to be younger.

The oldest sediments are comparatively young because. Except within a few kilometers of a ridge crest where the volcanic rock is still relatively young most parts of the sea floor are covered in sediments. Massive sulfide mineral deposits are common along the mid ocean ridges 4. Life may have originated at mid ocean ridges 3.

Oceanic crust the outermost layer of earth s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges which occur at divergent plate boundaries. It is composed of several layers not including the overlying sediment. However at deeper ocean floor such as hundreds to thousands of meters the sediments become lithified. More than half of the earth s surface formed at a mid ocean ridge 2.

1 basaltic rock is found to be progressively younger at increasing distances from a mid ocean ridge 2 marine fossils are often found in deep well drill cores 3 the present continents appear to fit together as pieces of a larger land mass 4 areas of shallow water seas tend to accumulate sediment which gradually sinks also please help me with. Youngest oceanic crust is near the ridges. In tropical regions ocean islands tend to be surrounded by carbonate reefs. Which evidence supports the theory of seafloor.

Smaller aquatic animals tend to live in the shallower regions and the larger animals live in the deeper regions generally along the continental shelves beneath the waves. Scentists discovered that seafloor is relatively young because there is no sediments that are older than 150 million years were discovered. The ocean floor sediments near the surface remain unconsolidated. Almost all of the sea floor is covered by young sediments and sedimentary rocks derived either from erosion of continents or from marine biological processes.

This material comes from several different sources and is highly variable in composition depending on proximity to a continent water depth ocean currents biological activity and climate. C the oldest oceanic crust is present only near trenches. A the rocks of the underlying ocean floor react chemically with the lowest sediments converting them directly into rock b the ocean floor is recycled through plate tectonics dragging the oldest sediments into the mantle at subduction zones. Most of the volcanic eruptions and earthquakes occur along the mid ocean ridges.

Oceanic crust is about 6 km 4 miles thick. Oldest oceanic crust is only present near trenches d. Plankton is found distributed throughout the world s oceans and is a vital ingredient in the success of many marine animals. Deeper regions of the ocean floor tend to be younger b.
