(Read pages 6869 in Exploring Geology 1stand 3rd editions [6667 in2nd edition], then close the book and answer the questions.) In 1520 words, explain how the age of the seafloor and the thickness of theoverlying layer of sediment varies on either side of a midocean ridge.The further you move out from the ridge, the older the seafloor will be, and the more sedimentthere will be. Example answer:Moving away from the midocean ridge, the crust is increasingly older and the thickness ofsediment increases.Comment:(Read page 276 in Exploring Geology 3rd edition [277 in 2nd edition, 281 in 1st edition], thenclose the book and answer the four questions below.)Where are hot spots most likely to be found?
