Answer:
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.
