Theory of seafloor spreading

WebbSeafloor spreading was proposed by an American geophysicist, Harry H. Hess in 1960. By the use of the sonar, Hess was able to map the ocean floor and discovered the mid … WebbBy the 1960s, the theories of continental drift and sea floor spreading were supported by reliable scientific data and combined to develop modern‐day plate tectonic theory. The theory maintains that the crust and uppermost mantle, or lithosphere, is segmented into a number of solid, rigid slabs called lithospheric plates.

In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. What is the evidence for sea-floor spreading?

Seafloor Spreading Theory, Evidence, Example, Diagram

Seafloor spreading helps explain continental drift in the theory of plate tectonics. 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 rid… WebbQuarter 1 Science 10 Lesson on Seafloor Spreading.
