What evidence supports the theory of plate tectonics?
The shape of the continents, the distribution of earthquakes, the symmetric magnetic banding of the sea floor ether side of the mid oceanic ridges, the mid oceanic ridges, back arc basins, deep sea trenches, the fiery ring of the Pacific, The distribution and chemistry of volcanoes, atolls, paleo magnetism, fossil evidence and the distribution of species. (there may be more evidence).
What theory combined sea floor spreading and continental drift?
Plate Tectonics
What discovery did scientist make when comparing the age of the sea floor to that of the continents?
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
Which theory suggested that the earth was once a single supercontinent that gradually broke up into the continents that we know today?
Sea floor spreading Subduction Plate tectonics Continental sift theory
Identify how magnetic symmetry can be used as evidence of sea floor spreading?
As the sea floor spreads the magnetic orientation in the rocks as they cooled is preserved. As the earth's magnetic field changes then a distinct pattern is imprinted in the rocks. If sea floor spreading is true then this unique pattern should be the same on both sides from the spreading point. Measurements of sea bottom rocks verify this symmetry is true. :)
What three pieces of edivence for Wegeners theory can from the sea floor?
Plants,animals,and something else
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
Which one of the following pieces of evidence did Wegener use to support his theory of continental drift?
the age of the rocks in the sea floor is all the same
What do scientists now know about earth that would have answered the scientists who rejected wegeners theory?
the sea-floor spreading, and the movement of tectonic plates
What provides the most evidence for the theory of plates tectonic?
The spreading of the sea floor.
What are two pieces evidence for cracks in the ocean floor?
molten material and drilling samples
What is the name of the newer theory that replaced Wegeners theory?
In the 1960s, researchers discovered several mountain ranges on the ocean floor. These mountains suggested that the earth's crust consists of 20 slabs or plates. The discovered led to a new theory called "Plate Tectonics."
What are pieces of evidence of sea floor spreading?
molten material,drilling samples, and magnetic stripes
What are two pieces of evidence that support the theory of sea floor spreading?
1) mapping of magnetic reversals 2) the nice fit you get by placing places like South America and Africa next to each other. ( &3) fossil evidence of both plants and animals.)
Why was sea floor spreading not known during wegeners lifetime?
There was a lack of technology.
What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
What are two pieces of evidence for sea-floor spreading?
Magnetic stripes and absolute ages of seafloor basalt.
