Samples from the seafloor around the Mid-Atlantic Ridge and the East Pacific Rise show that both areas have been creating new material in the last five million years.Samples from the East Pacific Rise show the five-million-year-old seafloor is three times as wide as similarly aged material from the Mid-Atlantic Ridge.What does this say about the rate of seafloor spreading in the East Pacific?

Question

Quizplus · Accepted Answer

The fact that the five-million-year-old seafloor at the East Pacific Rise is three times as wide as similarly aged material from the Mid-Atlantic Ridge suggests that the rate of seafloor spreading is slower at the East Pacific Rise compared to the Mid-Atlantic Ridge. Therefore, the seafloor at the Mid-Atlantic is growing more slowly than the seafloor at the East Pacific Rise.
