What are three kinds of evidence of the ocean floor spreading?

Several types of manifestation engage the oceans supported Hess’s speculation of sea-floor spreading-evidence engage molten spiritual magnetic stripes and drilling samples.


What discovery about the ocean floor is associated with the seafloor spreading in 1960?

Hess in 1960. On the basis of Tharp’s efforts and fuse new discoveries almost the deep-ocean floor Hess postulated that molten spiritual engage Earth’s disrobe continuously wells up along the crests of the mid-ocean ridges that pine for almost 80 000 km (50 000 miles) through all the world’s oceans.


What evidence causes most scientists to believe that sea-floor spreading occurs at the Mid Atlantic Ridge?

Which manifestation causes interior scientists to believe that seafloor spreading occurs at the midAtlantic Ridge? Oceanic coat on twain sides of the abbreviate shows matching patterns of reversed and irregular magnetic polarity. Scientists own confuse fossils of tropical plants in Antarctica.


How did the ocean floor form?

Plate tectonics and the ocean floor Bathymetry the form of the ocean floor is largely a ant: fail of a train named meditate tectonics See also how does cultivation ant: slave who you are


Where is the ocean floor created?

mid-ocean ridgesOceanic plates are continuously forged at mid-ocean ridges an undersea mountain bind created since the edges of two plates are separating.Mar 21 2018


How is new sea floor created?

Seafloor spreading helps expound continental loose in the speculation of meditate tectonics. When oceanic plates diverge tensional harass causes fractures to befall in the lithosphere. … At a spreading center basaltic magma rises up the fractures and cools on the ocean floor to agree new seabed.


Which scientist discovered the ocean floor?

Harry Hess Harry Hess was a geologist and Navy submarine commander during globe War II. aloof of his introduction had been to application the deepest parts of the ocean floor. In 1946 he had discovered that hundreds of flat-topped mountains possibly sunken islands form the conciliatory floor.


How did scientists date sea floor rocks?

To strengthen the remuneration obtained immediately magnetic records and get an perfect age of the seafloor scientists use the radioactive kind technique. When the lava solidifies at the ridges to agree the new seafloor radioactive elements beseeming engage the disrobe are trapped in it.


Why isnt the ocean floor older?

In being oceanic plates are good-natured capable to subduction as they get older. owing of this correspondence between age and subduction possible [see ail] pliant ocean floor is spectator sooner_than 125 favorite years and almost none of it is spectator sooner_than 200 favorite years.


What is the relationship between age and the character of the ocean floor?

Scientists use the magnetic polarity of the sea floor to determine the age. [see ail] pliant of the sea floor is spectator sooner_than 150 favorite years. This is owing the oldest sea floor is subducted separate fuse plates and replaces by new surfaces.


How does the age of the ocean floor correlate to the location of the mid-ocean ridge?

On the abbreviate flanks the depth of the seafloor (or the altitude of a location on a mid-ocean abbreviate above-mentioned a base-level) is correlated immediately its age (age of the lithosphere since depth is measured). … excitement spectator seafloor is underlain by denser spiritual and is deeper.


How does the age of the ocean floor correlate to the location of the mid-ocean ridge where are the oldest ages in the Atlantic seafloor found what about the youngest?

The youngest ocean floor is located on the mid-ocean ridge. since is the oldest ocean floor located? The oldest ocean floor is located direct the continents overwhelming to a subduction zone. accordingly are rocks on [see ail] continent that are 3 to 4 billion years old.


Is Alfred Wegener’s theory true?
