Sea Floor Spreading Is Driven By Volcanic Activity

Sea floor spreading is driven by volcanic activity.

Sea floor spreading is driven by volcanic activity.

At a spreading. In the middle of abyssal plains along mid ocean ridges at the edges of continental shelves along fracture zones. Seafloor spreading is driven by volcanic activity that occurs. Marine magnetic anomalies can be used to estimate the.

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. Seafloor spreading and other tectonic activity processes are the result of mantle convection. During a journey to the center of earth one would experience temperature.

Rate of seafloor spreading. Along mid ocean ridges. Rates of seafloor spreading in the atlantic ocean are compatible with what is known about the breakup of pangaea. Marine magnetic anomalies result from seafloor spreading in conjunction with.

And pressure both increasing. Rock eroded away and deposited in ocean basin volcano erupts through ocean floor. Seafloor spreading is driven by volcanic activity. Question 2 1 5 1 5 points.

Convection currents carry heat from the lower mantle and core to the lithosphere. 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. In the middle of abyssal plains b. 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.

Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. Plates that are not subducting are driven by gravity sliding off the elevated mid ocean ridges a process called ridge push. Hydrothermal structures such as pipes and pockmarks mainly occur in the proximity of volcanoes or accompany volcanic groups. Recycles old oceanic crust.
