Spreading centers with high spreading rates, such as those where plates are diverging rapidly, are characterized by a long, gently sloping ridge. the ridge forms as a well-developed magma chamber beneath causes the rock to swell upward. in contrast, spreading centers with slow spreading rates have poorly developed magma chambers and a well-defined rift valley developed at the center of the ridge. drag the appropriate labels to their respective targets. you do not need to use all labels. view available hint(s)

Answer and explanation;

Slow spreading rate

Top middle- rift valley  

Top Right- poorly- developed magma chamber

Rapid Speading rate

Top left- Swell

Top Right- Well- Developed magma chamber

Bottom middle- Diverging plates

Explanation;

-Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

-This is what happens at the mid-oceanic ridge where a divergent boundary is causing two plates to move away from one another resulting in spreading of the sea floor. As the plates move apart, new material wells up and cools onto the edge of the plates.
