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:
3. along
Explanation:
If an oceanic trench formed along the East Coast of North America, the deepest earthquakes related to the subduction of the oceanic plate beneath North America would occur along the eastern coastline.
Oceanic trenches results from the convergence of two plates, they are a common site for earthquakes. Since the trench is along the East Coast of Northern America, the earthquake will most likely occur along the Eastern coastline.
Your answer would be B. The most dangerous job in the United States. Because the cave can come down, if you don't have the right equipment you can damage your lungs, and you may get stuck down there, or really hurt.
