Researchers find an interesting geological formation on the ocean floor. how can they tell whether plates are colliding or moving apart due to spreading seafloor in this region? a. if the seafloor has relatively little sediment and is young, then it is spreading there. b. if the seafloor has evidence of wrinkling, then the seafloor must be spreading. c. if the seafloor has relatively little sediment and is young, then plates are colliding there. d. if the seafloor has many volcanoes, then it must be spreading and the plates are not converging. read more on -

The correct answer is option B, that is, if the seafloor has evidence of wrinkling, then the seafloor must be spreading.

Explanation:

In order to judge that whether the seafloor is colliding or spreading there is a need to look for the usual geological formations in both the cases. In the case of seafloor spreading, the presence of mid-ocean ridge takes place on the floor of the sea, which will signify that the plates are moving apart from each other. This spreading of sea-floor can be demonstrated by the evidence of wrinkling.
