What boundaries destroy sea floor?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Is new sea floor created or destroyed at mid-ocean ridges?
Answer 1: You are correct that the seafloor is destroyed at subduction zones, but it is simultaneously being created at mid-ocean ridges. see figure 1 .
Which two tectonic plates are separated by a mid ocean ridge?
The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.
What did scientists notice when they observed the mid-ocean ridge?
What did scientists in a submersible see when they observed the mid-ocean ridge? They discovered this by finding the age of rock samples obtained by drilling in the ocean floor. A deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle.
Is formed when the ocean floor moves on either side of a mid ocean ridge?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
How does sediment that is closer to a mid ocean ridge compare to sediment that is farther away?
How does sediment that is closer to a mid-ocean ridge compare to sediment that is farther away? It is larger. It is smaller.
What is the most conclusive proof for the continental drift?
The old data from continental rocks, once soundly rejected, have been exhumed and exalted as conclusive proof of drift.
Where were the youngest rocks on the sea floor?
mid-ocean ridges
When two continental crust converge both crust exert a pressure pushing each other as the ground rises a tall landform is created is it possible to erupt?
No, the tall landform created would be a mountain or a mountain range, which means it won’t erupt. 2. Subduction does not take place when 2 continental crusts converge because there is no crust that subducts.
Where on earth can you find transform boundaries?
Transform boundaries Tuzo Wilson, who proposed that these large faults or fracture zones connect two spreading centers (divergent plate boundaries) or, less commonly, trenches (convergent plate boundaries). Most transform faults are found on the ocean floor.
