If china has a population of 1,355,935,022 people and an area of 3,705,405 mi^2 what is the population density of china?
a.
77 people/mi^2
b.
123 people/mi^2
c.
0.00273 people/mi^2
d.
366 people/mi^2

The right option is; d. 366 people/mi^2

Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.  

From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.

Population Density = Number of People / Land Area.

Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.

Therefore, the population density of China is 366 people per square mile.

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.
