Diagram of seafloor spreading
Websea-floor spreading the process of adding more crust to the ocean floor deep-ocean trench deep valley or underwater canyon where the oceanic crust sinks back toward the mantle … WebWhen two tectonic plates split apart from each other a geologic process called seafloor spreading happens. 4. As tectonic plates converge, the other plate slides beneath the other plate or subduct. This process is called subduction. 5. As two tectonic plates split apart mid- ocean ridge is formed.

WebMay 1, 2024 · While the ocean has an average depth of 2.3 miles, the shape and depth of the seafloor is complex. Some features, like canyons and seamounts, might look familiar, while others, such as hydrothermal vents and methane seeps, are unique to the deep. This graphic shows several ocean floor features on a scale from 0-35,000 feet below sea level. WebThe pieces of evidence gathered for sea-floor spreading include the evidence from molten material, magnetic stripes, and drilling samples. b. The central valley of the mid-ocean ridges resembles pillows or toothpaste that was squeezed out from a tube. These shapes indicate that the new rocks are formed when the molten material solidifies.

When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. 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. Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ri… how to scan computer for issuesWebThe seafloor spreading hypothesis was proposed by the American geophysicist Harry H.
