how seafloor spreading, isotopic dating of rocks, and magnetic pole reversals all give supporting evidence to?
Can you explain how seafloor spreading, isotopic dating of rocks, and magnetic pole reversals all give supporting evidence to the plate tectonics theory?
sea floor spreading is something we can clearly see happening (visual evidence)
isotopic dating ( carbon dating) give evidence that some rocks are older than other rocks. we can determine ages of the strata in the bedrocks under the sea... can show that rocks in the expansion zones are newer than the older rocks in the center of a plate for example.
the earth reverses its magnetic pole ever X amount of years(sry dont remember how many) but when rock is molten some elements in the rock will align them selves with the poles. They can look at these rocks and see some face one way and some face another way and they can determine that these rocks were formed when the poles were facing a specific direction
