However at deeper ocean floor such as hundreds to thousands of meters the sediments become lithified.

Deeper regions of the ocean floor tend to be younger.

The ocean floor sediments near the surface remain unconsolidated. Youngest oceanic crust is near the ridges. 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. Oceanic crust is about 6 km 4 miles thick.

Life may have originated at mid ocean ridges 3. Oldest oceanic crust is only present near trenches d. In tropical regions ocean islands tend to be surrounded by carbonate reefs. 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. Most of the volcanic eruptions and earthquakes occur along the mid ocean ridges. 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. Scentists discovered that seafloor is relatively young because there is no sediments that are older than 150 million years were discovered.

Plankton is found distributed throughout the world s oceans and is a vital ingredient in the success of many marine animals. 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. C the oldest oceanic crust is present only near trenches. B the pacific is larger than the atlantic because it contains older oceanic floor.

A deeper regions of the ocean floor tend to be younger. Massive sulfide mineral deposits are common along the mid ocean ridges 4. Clastic sediments some quite coarse predominate on shelves and slopes. Which evidence supports the theory of seafloor.

The oldest sediments are comparatively young because. Deeper regions of the ocean floor tend to be younger b. 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. 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.
