Which of the following is associated with a mid-ocean ridge?
A) an island arc
B) magma produced as the mantles rise up
C) melting of the subducting plate
D) lower topography than surrounding seafloor
E) continental rift
Mid-ocean Ridge
An underwater mountain range, formed by plate tectonics, that encircles the globe, marked by volcanic activity and seafloor spreading.
Island Arc
A curved chain of volcanic islands located at a tectonic plate margin, formed by the subduction of an oceanic plate.
Mantles Rise
The upward movement of mantle material in the Earth, often related to thermal convection and tectonic processes.

Final Answer :
B
Explanation :
Mid-ocean ridges are characterized by magma production as the mantle rises up due to divergent tectonic plates pulling apart, allowing magma to rise and solidify, forming new oceanic crust.
