This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century.

Sea floor spreading is driven by volcanic activity.

Seafloor spreading is driven by volcanic activity. Recycles old oceanic crust. At a spreading. Marine magnetic anomalies result from seafloor spreading in conjunction with.

Plates that are not subducting are driven by gravity sliding off the elevated mid ocean ridges a process called ridge push. Seafloor spreading is driven by volcanic activity. Question 2 1 5 1 5 points. Hydrothermal structures such as pipes and pockmarks mainly occur in the proximity of volcanoes or accompany volcanic groups.

And pressure both increasing. Rates of seafloor spreading in the atlantic ocean are compatible with what is known about the breakup of pangaea. Marine magnetic anomalies can be used to estimate the. Along mid ocean ridges.

In the middle of abyssal plains along mid ocean ridges at the edges of continental shelves along fracture zones. Mantle convection is the slow churning motion of earth s mantle. Rock eroded away and deposited in ocean basin volcano erupts through ocean floor. 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.

Convection currents also recycle lithospheric materials back to the mantle. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. During a journey to the center of earth one would experience temperature. Seafloor spreading is driven by volcanic activity equal to summed over the entire surface of earth the rate of spreading at divergent boundaries is lithospheric consumption at subduction zones.

Pipes pockmarks and localized amplitude anomalies mainly constitute the magmatic hydrothermal systems which are probably driven by post seafloor spreading volcanoes plutons. Rate of seafloor spreading. Sea floor spreading is driven by volcanic activity. Seafloor spreading and other tectonic activity processes are the result of mantle convection.
