Question
Mid-ocean ridges are steeper and less broad than rises because:
Group of answer choices
A) the rocks of the mid-ocean ridges are composed of more dense mineral than the rises.
B) the rocks of the mid-ocean ridges are composed of less dense mineral than the rises.
C) The seafloor spreading rate of ridges are faster than rises causing the oceanic crust to subside closer to the ridge axis.
D) The seafloor spreading rate of ridges are slower than rises causing the oceanic crust to subside closer to the ridge axis.
E) Every ridge is composed of continental crust.
Answer:
The correct answer is D.
Explanation:
In volcanic regions, as the molten magma flows out onto the seafloor creating new beds, the faster it flows, the less steep the mid-ocean ridge is. If however, it is slow-flowing, then oceanic lithosphere formed cool closer to the ridge axis thus making it very steep.

Answer: Bananas and coconuts
Explanation:
Ocean ridge does not accompany volcanic activity in the Pacific Northwest.
<u>Explanation:</u>
In this process the denser oceanic plate force the thinner continental plate to sink into the mantle. This region is referred as subduction zone, where it results in intense volcanic eruptions and earthquakes.
The denser Pacific plate sinks because of the chunk pull impact and it likewise prompts the development of mountains. This sort of impact creates profound center seismic tremors.
It isn't related with the maritime edge as the mid-maritime edge shapes in a disparate plate limit. In the Pacific Northwest , the volcanic activity is carried out by the geological process majorly by subduction.
