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.
Hydrothermal structures such as pipes and pockmarks mainly occur in the proximity of volcanoes or accompany volcanic groups.
Rock eroded away and deposited in ocean basin volcano erupts through ocean floor.
Marine magnetic anomalies result from seafloor spreading in conjunction with.
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.
And pressure both increasing.
Seafloor spreading and other tectonic activity processes are the result of mantle convection.
Seafloor spreading is driven by volcanic activity that occurs.
Sea floor spreading is driven by volcanic activity.
Seafloor spreading is driven by volcanic activity.
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.
Mantle convection is the slow churning motion of earth s mantle.
Pipes pockmarks and localized amplitude anomalies mainly constitute the magmatic hydrothermal systems which are probably driven by post seafloor spreading volcanoes plutons.
Rates of seafloor spreading in the atlantic ocean are compatible with what is known about the breakup of pangaea.
Convection currents also recycle lithospheric materials back to the mantle.
Marine magnetic anomalies can be used to estimate the.
Convection currents carry heat from the lower mantle and core to the lithosphere.
In the middle of abyssal plains b.
In the middle of abyssal plains along mid ocean ridges at the edges of continental shelves along fracture zones.
Recycles old oceanic crust.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
Rate of seafloor spreading.
Question 2 1 5 1 5 points.

During a journey to the center of earth one would experience temperature.
