How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Ocean ridges and deep-sea trenches support the theory of sea floor spreading through the process of plate tectonics. At ocean ridges, new oceanic crust is formed as magma rises and solidifies, pushing the existing crust apart. Deep-sea trenches are areas where old oceanic crust is being subducted back into the mantle, completing the cycle of sea floor spreading. This continuous movement of crust at ridges and trenches provides evidence for the theory of sea floor spreading and the movement of tectonic plates.
What do magnetic reversals help support?
Magnetic reversals in Earth's history help support the theory of plate tectonics by providing evidence of seafloor spreading and the movement of lithospheric plates. They also assist in dating rocks and determining the age of oceanic crust.
What scientist helped to discover the process of sea floor spreading?
The scientist who helped to discover the process of sea floor spreading was Harry Hess, an American geologist. He proposed the theory in the early 1960s, which revolutionized our understanding of plate tectonics and the movement of Earth's crustal plates. Hess's hypothesis helped explain the geomorphology of the ocean basins and the distribution of earthquakes and volcanic activity.
What was dan mckenzie's hypothesis?
Dan McKenzie's hypothesis, proposed in 1967, suggested that the Earth's lithosphere is divided into a series of rigid plates that move horizontally over the weaker asthenosphere. This hypothesis formed the basis of the theory of plate tectonics.
Who Used sonar to prove sea floor spreading?
The researchers who used sonar to provide the first detailed evidence of sea floor spreading were Bruce Heezen and Marie Tharp in the early 1950s. Tharp's mapping of the Atlantic Ocean floor using sonar revealed the presence of the Mid-Atlantic Ridge and provided crucial support for the theory of plate tectonics.
Which was not included in the support for harry hess's hypothesis of sea-floor spreading?
One key piece of support that was not included in the initial support for Harry Hess's hypothesis of seafloor spreading was the mechanism of plate tectonics. This idea was developed and integrated into the theory of seafloor spreading by geologists like Robert Dietz and J. Tuzo Wilson at a later stage.
The ways that fossils helped support the hypothesis of continental drift?
Because of sea floor spreading
Summarize the ways that fossils helped support the hypothesis of the continental drift?
Because of sea floor spreading
What was Arthur Holmes' hypothesis?
Spreading ocean floor
What was the hypothesis of the sea-floor spreading?
excess nutrients in the water
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
What is the most important in providing support for the sea floor spreading hypothesis?
"Magnetic Polarity: the North and South magnetic poles have switched positions throughout Earth's history... the record of magnetic polarity in the rocks of the ocean floor provided unequivical support for the seafloor spreading hypothesis." - as quoted in chp. 4, pg. 94, from the textbook "The Good Earth: Introduction To Earth Science"
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
What magnetic reversals help support?
the theory of sea-floor spreading
Describe how magnetism is used to support the theory of seafloor spreading?
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.
What was Alfred wegner's hypothesis for continental drift?
He thought that the world was once pangea but then the plates and "Sea Floor Spreading" moved Pangea around
What is a spreading center on the ocean floor?
