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.

The impact of ancient Rome on western civilization cannot be hibernated. Though it has been thousands of years since the reign of the Roman Empire, but the traces are still evident in today's world. Some of the notable impacts can be found in today's architecture, arts, laws, engineering, constructions, languages etc. It is said that the Latin language, which was spoken by the Romans, went as far as Western Europe and many languages emerged from Latin. These languages are called the "Romance languages." They include Spanish, French, Italian, Romanian and Portuguese. As a result of this, over 800 million people around the world speak a Romance language. Rome is also associated with the Catholic church, it is believed that the Romans helped spread Christianity in Europe, and today it is the largest religion in the world.
Answer:
On their mode of formation
Explanation:
The classification of rocks into three major categories is strictly based on their mode of formation.
Rocks are naturally formed aggregates of minerals. Based on mode of formation, they can be classified into;
- Igneous rocks: these rocks are formed by the cooling and solidification of molten magma.
- Sedimentary rocks are formed by the compaction and lithification of sediment.
- Metamorphic rocks: these are changed rocks that have been formed by subjecting rocks to pressure and temperature conditions which causes an alteration of their minerology.
