D. Rock type
Explanation:
The major factor that influences the strength of rocks is the rock type.
Different rock types are known to have their own relative strength.
Based on their strength, rocks are classified into hard and soft rocks.
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered.
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions.
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions.
Hard rocks are used for heavy duty and durable constructions like dams and bridges.

As with igneous and sedimentary rocks, metamorphic rocks are classified on the basis of texture (grain size, shape, orientation) and mineral composition. However, the classifiction of metamorphic rocks is more difficult to get into than with igneous and sedimentary rocks, for a couple of reasons.
Answer:
C
Explanation:
The water cycle is powered by heat from the Sun that allows water to change phase. Solar heating causes surface water to evaporate and join the atmosphere as water vapor. The water vapor then condenses to form clouds and, depending on the height of the clouds and the latitude, falls as solid or liquid precipitation back to the surface.
Without solar heating, all the water on Earth would freeze solid and there would be no atmosphere or rain.
This breed is called metamorphic rocks - rocks formed in the Earth's crust as a result of metamorphism, ie the change of sedimentary and igneous rocks due to changes in physical and chemical conditions
