If the earth did not have internal energy, which of the following carbon cycle process would not be possible?

a. respiration

b. consumption

c. rock formation

d. burning fossil fuels

If the Earth did not have internal energy, the carbon cycle process which would not be possible is: C. rock formation.

Carbon cycle can be defined as the series of biogeochemical processes through which atoms of carbon or carbon compounds are interconverted and used within an environment, by transporting carbon from the atmosphere to the Earth and then back to the atmosphere.

Basically, the four (4) main processes associated with carbon cycle include the following:

Of all the aforementioned processes, only rock formation requires that the Earth has sufficient internal energy for the movement of materials around the core and the mantle, thereby, leading to gradual but significant changes within the Earth's crust.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
