Deeper Regions Of The Ocean Floor Tend To Be Younger

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.

Deeper regions of the ocean floor tend to be younger.

In tropical regions ocean islands tend to be surrounded by carbonate reefs. More than half of the earth s surface formed at a mid ocean ridge 2. The oldest sediments are comparatively young because. 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.

Oldest oceanic crust is only present near trenches d. Massive sulfide mineral deposits are common along the mid ocean ridges 4. Youngest oceanic crust is near the ridges. Most of the volcanic eruptions and earthquakes occur along the mid ocean ridges.

Deeper regions of the ocean floor tend to be younger b. Clastic sediments some quite coarse predominate on shelves and slopes. 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.

Which evidence supports the theory of seafloor. B the pacific is larger than the atlantic because it contains older oceanic floor. Scentists discovered that seafloor is relatively young because there is no sediments that are older than 150 million years were discovered. However at deeper ocean floor such as hundreds to thousands of meters the sediments become lithified.

A deeper regions of the ocean floor tend to be younger. 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. The pacific is larger than the atlantic because it contains older oceanic floor c. It is composed of several layers not including the overlying sediment.

Plankton is found distributed throughout the world s oceans and is a vital ingredient in the success of many marine animals. 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. Life may have originated at mid ocean ridges 3. The ocean floor sediments near the surface remain unconsolidated.
