- As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material splits apart the strip of solid rock that formed before, pus … hing it aside. This process is called Sea Floor Spreading, continually adds new material tot the ocean floor.

- The interaction between the tectonic and the hydrologic systems causes constant recycling of the materials of the Earth's crust. Rocks are heated, metamorphosed, melted, weathered, sediment is transported, deposited and lithified, then it may be metamorphosed again in yet another cycle.

Seafloor spreading Age of oceanic crust; youngest (red) is along spreading centers. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.Seafloor spreading helps explain continental drift in the theory of plate tectonics.t the Mid-Atlantic Ridge (and in other areas), material from the upper mantle rises through the faults between oceanic plates to form new crust as the plates move away from each other, a phenomenon first observed as continental drift.

What is Permineralization? Many petrified fossils are marine organisms that fell to the bottom of the ocean and were covered in sediment. The permineralization process is very slow. It happens as water seeps through the sediment that covers an organism; the sediment helps keep the organism intact, and the mineralized water slowly works its way into the remains.

High School Earth Science/Relative Ages of Rocks A series of sedimentary beds is deposited on an ocean floor. The sediments harden into sedimentary rock. The sedimentary rocks are uplifted and tilted, exposing them above the ocean surface. The tilted beds are eroded by rain, ice, and wind to form an irregular surface. A sea covers the eroded sedimentary rock layers.

Seafloor spreading Age of oceanic crust; youngest (red) is along spreading centers. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.Seafloor spreading helps explain continental drift in the theory of plate tectonics.he destruction of oceanic crust occurs at subduction zones where oceanic crust is forced under either continental crust or oceanic crust. Today, the Atlantic basin is actively spreading at the Mid-Atlantic Ridge. Only a small portion of the oceanic crust produced in the Atlantic is subducted.

Seafloor Spreading Seafloor spreading is one of the two major processes of plate tectonics, the other being subduction. Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat. This can result in an ever-widening seafloor at the expense of area lost elsewhere on the planet. Seafloor spreading ends when midocean ridges are subducted.

- The mid-ocean ridge in the middle of the Atlantic Ocean is known as the Mid-Atlantic Ridge (MAR). At the MAR, new sea floor rock (basalt) is added to the edges of the North American, South American, Eurasian, and African plates.ackground. Sea floor spreading is one component of the theory of plate tectonics. According to this concept, at ridges in many of the world's oceans (mid-ocean ridges), new crustal rock is added to the edges of plates on either side of the mid-ocean ridge.

Zio Patch: New Ambulatory Heart Monitor Patients must also keep a log of symptoms while the monitor is worn so that the physician can match the symptoms to the monitor results. Researchers at Scripps Health believe that a new digital device, the Zio Patch, may be a viable -- and more patient-friendly -- alternative to the Holter monitor.

Aeolian Transport Aeolian Transport is the first process of coastal dune formation and involves the movement and weathering of sand particles behind and parallel to the shoreline. There are three main processes involved in Aeolian Transport: 1  Suspension-The finer sand particles are moved by the wind, high in the air.

Deposition (geology) Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, and water, as well as sediment flowing via gravity, transport previously eroded sediment, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

Why are old rocks rare on the ocean floor? Why don't you find really old rocks on the ocean floor? The ocean floor is constantly recycling itself though a process called subduction by which the oldest layers of the oceanic crust, which are heavier, are driven under the ligh … ter layers of either oceanic crust or continental crust where they descend to depths in the earth that melt them into magma.

Seafloor spreading Mid-ocean ridge - Description. 1  Mid-ocean ridges are geologically active, with new magma constantly emerging onto the ocean floor and into the crust at and near rifts along the ridge axes. 2  The rocks making up the crust below the seafloor are youngest along the axis of the ridge and age with increasing distance from that axis. New magma of basalt composition emerges at and near the axis because of decompression melting in the underlying Earth's mantle.

- The rising of hot rock from the mantle to Earth’s surface is called upwelling. This process adds new material to tectonic plates. In a June 2013 study in Nature, Conrad and other researchers found massive, extra-hot regions of mantle beneath Africa and the central Pacific Ocean. The scientists concluded these were major areas of upwelling.

What is upwelling? Upwelling occurs when winds blowing across the ocean surface push water away from an area and subsurface water rises up to replace the diverging surface water. Upwelling occurs in the open ocean and along coastlines. The reverse process, called downwelling, also occurs when wind causes surface water to build up along a coastline. The surface water eventually sinks toward the bottom. Subsurface water that rises to the surface as a result of upwelling is typically colder, rich in nutrients, and biologically productive.

seafloor spreading unmoving oceans. Seafloor spreading proves that the ocean itself is a site of tectonic activity. Keeping Earth in Shape Seafloor spreading is just one part of plate tectonics. Subduction is another. Subduction happens where tectonic plates crash into each other instead of spreading apart.
