Sea Floor Spreading Is Driven By Volcanic Activity

Convection currents carry heat from the lower mantle and core to the lithosphere.

Sea floor spreading is driven by volcanic activity.

Rock eroded away and deposited in ocean basin volcano erupts through ocean floor. And pressure both increasing. Seafloor spreading is driven by volcanic activity. During a journey to the center of earth one would experience temperature.

Marine magnetic anomalies can be used to estimate the. Marine magnetic anomalies result from seafloor spreading in conjunction with. Seafloor spreading is driven by volcanic activity that occurs. Rates of seafloor spreading in the atlantic ocean are compatible with what is known about the breakup of pangaea.

Seafloor spreading and other tectonic activity processes are the result of mantle convection. Hydrothermal structures such as pipes and pockmarks mainly occur in the proximity of volcanoes or accompany volcanic groups. 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. Plates that are not subducting are driven by gravity sliding off the elevated mid ocean ridges a process called ridge push.

Mantle convection is the slow churning motion of earth s mantle. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. Recycles old oceanic crust. In the middle of abyssal plains b.

Question 2 1 5 1 5 points. Pipes pockmarks and localized amplitude anomalies mainly constitute the magmatic hydrothermal systems which are probably driven by post seafloor spreading volcanoes plutons. Seafloor spreading is driven by volcanic activity. Rate of seafloor spreading.

In the middle of abyssal plains along mid ocean ridges at the edges of continental shelves along fracture zones. Sea floor spreading is driven by volcanic activity. At a spreading. 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.
