Seafloor Spreading Is Driven by Volcanic Activity

Geography High School answered Seafloor spreading is driven by volcanic activity that occurs. Hydrothermal activity along mid-ocean ridges helps explain why ice ages come and go according to a UConn marine scientist.

Near the continental shelf B.

. The plates are thought to be driven by a convection current mechanism that is deep within the earth. Plates move together separate and slide past each other creating regions of volcanic activity mountain building and earthquakes. Along transform margins E.

A great deal of activityvolcanoes earthquakes fault zones trenchestake place along these ridges. In the middle of abyssal plains. Frequency of sunspot activity.

Seafloor Spreading The mechanism by which new seafloor crust is created at oceanic ridges and slowly spreads away as plates are separating. Seafloor spreading is driven by volcanic activity Group of answer choices in the middle of abyssal plains. Which of the following variables could influence the width of marine magnetic anomalies on the floor of the ocean.

At the edges of continental shelves. The release of molten rock through volcanic vents or fissures is driven by seafloor spreading and decompression melting of the upper mantle the partially molten layer just beneath the earths crust. Scientists Link Underwater Eruptions to Climate Change The climate-driven rise and fall of sea level matches up with seafloor ridges suggesting a link between ice ages and underwater volcanic.

Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ridge push. Sea-floor spreading is driven by volcanic activity that occurs primarily. At a spreading center basaltic magma rises up the.

Ob along fracture zones. This mechanism which is a more accurate version of Alfred Wegeners original drift of continents that plow through the sea was proposed by Harry Hess from Princeton University in the 1960sThis phenomenon is known to be caused by convection. In the middle of abyssal plains.

At the edges of continental shelves. Seafloor spreading is driven by volcanic activity a. Seafloor spreading is driven by volcanic activity that occurs along mid-ocean ridges.

In the middle of abyssal plains. In continental volcanic arcs D. Faster rates tend to.

The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically significant magma activity at spreading ridges. Seafloor spreading and other tectonic activity processes are the result of mantle convection. 1 day agoThis cycle is called seafloor spreading and its rate shapes many global processes including sea level and the carbon cycle.

The fastest tectonic plates on Earth move on average at a rate of approximately. At the edges of continental shelves. Duration of the magnetic polarity event C.

Seafloor spreading is a geologic process in which tectonic plate slarge slabs of Earths lithosphere split apart from each other. Because volcanic activity was presumed to be linearly dependent on seafloor production rate an increase in the global average seafloor spreading rate was modeled to drive a proportional increase in the volcanic CO 2. Along mid-ocean ridges C.

Sea floor spreading is the process by which continental drift occurs. Evidence for volcanic activity seems to extend out to 250 km westwards of the TdC island group as far as 1448W where we mapped a small volcanic cone on top of the abyssal hills of 10 Myr. This image is of a mid-ocean ridge.

7 hours agoThis cycle is called seafloor spreading and its rate shapes many global processes including sea level and the carbon cycle. Add your answer and earn points. The sea floor is spreading from the ocean ridges where new ocean crust is created and spreads outward.

See the answer Show transcribed image text Expert Answer 100 2 ratings. Rate at which the plates are moving away from the mid-ocean ridge B. Question 1 Seafloor spreading is driven by volcanic activity along mid-ocean ridges.

During periods of reverse polarity in the Earths magnetic field. Seafloor spreading builds new crust equally on both sides of the ridge. These are divergent-plate boundaries meaning that new material is.

It is now generally accented as part of the driving mechanism for plate tectonics. 1 day agoThis cycle is called seafloor spreading and its rate shapes many global processes including sea level and the carbon cycle. Faster rates tend to cause more volcanic activity which releases greenhouse gases so deciphering spreading rates helps contextualize long-term changes in the atmosphere.

See Page 1. Seafloor spreading is a part of the theory of plate tectonics. Faster rates tend to cause more volcanic activity which releases greenhouse gases so deciphering spreading rates helps contextualize long-term changes in the atmosphere.

The concept of sea-floor spreading was devised to explain the lack of very old Pre- Cambrian and Paleozoic oceanic crust. In the middle of abyssal plains. The release of molten rock through volcanic vents or fissures is driven by seafloor spreading and decompression melting of the upper mantle the partially molten layer just beneath the earths crust.

Were driven solely by slight imbalances in the input of carbon dioxide from volcanism and output via silicate-rock weathering.
