Question
What evidence has shown conclusively that the oceanic crust is geologically young and that the parallel magnetic striping pattern of basalts is symmetrical with regard to oceanic ridges?
radiometric dating of oceanic basalts and sequences from continents exclusively
radiometric dating of oceanic basalts and sequences from continents AND the unusually thin layer of oceanic sediments and ages of contained fossils
magnetic reversals contained in continental crusts that were at one time oceanic basalts
the existence of the same magnetic anomaly patterns in all ocean basins
the unusually thin layer of oceanic sediments and ages of contained fossils exclusively
a.radiometric dating of oceanic basalts and sequences from continents exclusively
b.radiometric dating of oceanic basalts and sequences from continents AND the unusually thin layer of oceanic sediments and ages of contained fossils
c.magnetic reversals contained in continental crusts that were at one time oceanic basalts
d.the existence of the same magnetic anomaly patterns in all ocean basins
e.the unusually thin layer of oceanic sediments and ages of contained fossils exclusively
Explanation / Answer
option b is the right answer
the layer of oceanic crust is the most rapidly changing upper layer of the earth because it is in direct relation with mantle and has high sediment concentration which makes erosion a very common and easy phenomenon
