Sea Floor Spreading Is An Example Of Which Plate Boundary

Seafloor spreading helps to explain continental drift in the theory of plate tectonics.

Sea floor spreading is an example of which plate boundary.

An example of a divergent plate boundary on continental lithosphere would be the east african rift valley. African rift valley red sea atlantic ocean. The red sea rift is a spreading center between two tectonic plates the african plate and the arabian plate it extends from the dead sea transform fault system and ends at an intersection with the aden ridge and the east african rift forming the afar triple junction in the afar depression of the horn of africa. Which list places the locations in the correct sequence with the initial seafloor spreading stage first followed by more advanced stages in the seafloor spreading process.

Seafloor spreading is just one part of plate tectonics. When the concept of seafloor spreading came along scientists recognized that it was the mechanism to explain how continents could move around earth s surface. At what plate boundary does the dense oceanic plate crust subduct beneath and the continental plate crust. These age data also allow the rate of seafloor spreading to be.

Convergent what helps scientists understand how the seafloor is spreading. Like the scientists before us we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically. The denser lithospheric material then melts back into the earth s mantle.

When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. The red sea is an example of plate boundary. E a continental continental divergent. Plate tectonics plate tectonics seafloor spreading.

Thus at convergent boundaries continental crust is created and oceanic crust is destroyed. At subduction zones the edge of the denser plate subducts or slides beneath the less dense one. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. The rate of sea floor spreading appears to be greatest in the pacific ocean because the radiometric age bands in the pacific ocean are narrower.

The red sea rift was formed by the divergence between the african plate and the. Subduction happens where tectonic plates crash into each other instead of spreading apart. Theory of plate tectonics. Natural or human made structures that cross a transform boundary are offset split into pieces and carried in opposite directions.

Two plates sliding past each other forms a transform plate boundary. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading. Rocks that line the boundary are pulverized as the. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process.
