Question

classify continental margins. 5 of 5. wide or narrow, shelves are made of continental crust and are classified as part of the continent, even though they are underwater. let’s now concentrate on seafloor features and start with the very long, north - south running feature in the middle of the atlantic ocean. when you’ve had a good look, let’s continue to proceed. what is this zig - zag feature that seems to split the atlantic ocean sea floor in half? a subduction zone a mid - ocean ridge a continuous strike - slip fault a chain of hot spots

Explanation:

The zig - zag feature that splits the Atlantic Ocean sea floor in half is a mid - ocean ridge. Mid - ocean ridges are long, underwater mountain ranges formed by plate tectonics as new oceanic crust is created at divergent boundaries. A subduction zone is where one plate is forced under another, a continuous strike - slip fault is a type of fault where plates slide past each other, and a chain of hot spots is related to volcanic activity from mantle plumes, none of which match the description of splitting the Atlantic sea floor.

Answer:

B. A mid - ocean ridge
