What does a model of the rock cycle show?

a. the amount of earths carbon cannot be determined

b. the amount of earths carbon increases

c. the amount of earths carbon decreases

d. the amount of earths carbon is constant

d. the amount of earths carbon is constant

Explanation:

Rock cycle is the name given to the natural process of transformation of the roots, capable of changing their moneralic composition. This cycle is proof that the terrestrial lithosphere has a dynamic character, which is the result of the actions of several endogenous and exogenous factors on the terrestrial surface. This cycle also allows us to understand how the amount of carbon in the earth is constant, allowing the transformation of the rocks in an evident way. It is through this process that we perceive the different types of rock that exist on the planet, if this process did not happen, the lithosphere would be composed only of magmatic rock.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
