What is one of the three social science principles of sustainability? a. a dependence on solar energy b. a focus on chemical cycling c. the degradation of natural capital d. a responsibility to future generations e. the ability to retain biodiversity

The correct answer is option B, A focus on chemical cycling

The five major principles of sustainability  are as follows:

a)Biodiversity  

b)Chemical Cycling  

c)Reliance on solar energy

d)nutrient recycling,  

e)Population control to reduce damage to the environment

The major goal of these principles is  to maintain a cohesive environment to produce a well-functioning alignment between societies, economy and individual and also save the resources for coming generations after fulfilling the need of present generation by planning an effective resource utilization map thereby disturbing the natural cycles "the least".

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
