What are two pieces of evidence for sea-floor spreading?
Magnetic stripes and absolute ages of seafloor basalt.
Give two pieces of evidence for seafloor spreading?
Geographic similarities between continental margins on both sides of the Atlantic Ocean and similarity of strata and fossils found on those margins.
What are pieces of evidence of sea floor spreading?
molten material,drilling samples, and magnetic stripes
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 is the difference between subduction and seafloor spreading?
Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate. Hope this helped :)

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.)
