Other than abundant matching fossils and sedimentary rock on opposite sides of the Atlantic Ocean and the apparent puzzle piece appearance of the continents on either side of the Atlantic, there is the presence of the mid-oceanic ridges, areas where new oceanic crust is created. The magnetic orientation of the basaltic oceanic crust as it forms is the mirror image of the magnetic orientation of the basaltic oceanic crust on the other side of the ridge, indicating that the seafloor is spreading in both directions away from ridge. Additionally, the dating of rock on the ocean floor has shown that oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached.
And finally, accurate measurements have been made by global positioning devices which verify that seafloor spreading is occurring.
- Mountains are cause as the tectonic plates push into each other, mountain ranges such as the Himalayas are constantly 'growing' and becoming taller.
- Giant rift's are constantly being formed on the land and under the ocean, one which keeps getting bigger is located in East Africa (cant remember the name). Anothers is marianas trench wich is in the ocean.
- Volcanos and tsmunmis are also caused by sea floor spreading.
its not happy
Rocks in the seafloor are moving one place to another
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
seafloor spreading
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.

seafloor spreading
evidence from molten material evidence from magnetic stripes evidence from drilling samples
pole reversals seafloor spreading
The Mid Atlantic Ridge
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
people here are stupid , really the answer is not hi
dumb question. don't want to write it all
Animal fossils have been found in many places in the ocean.
