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.
Cheers!
Answer:
Away from the ridge, where the sea floor is older and has more time to accumulate; also much thickest near continents

Capture, store, check, and display data related to position's on Earth's surface.
