Question

1. which statement is true about the image to the left? a. the image demonstrates subduction, and is why continental crust is older than oceanic crust. b the image demonstrates seafloor spreading and is why land is older at the ridge than at the far ends of the ridge. c. all of the above are true d. none of the above are true.

Explanation:

Seafloor spreading occurs at mid - ocean ridges where new oceanic crust is formed. In seafloor spreading, the youngest crust is at the ridge and it gets older as you move away from the ridge. Subduction is a different process where one tectonic plate moves under another. Continental crust is not older than oceanic crust because of subduction as described in option a. And in option b, land (oceanic crust here) is younger at the ridge and older at the far ends. So, all the statements in a and b are false.

Answer:

d. None of the above are true
