Answer:
Distance, some kind of distance or length.
Explanation:
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
Answer:
II. The reaction is exothermic.
III. The enthalpy term would be different if the water formed was gaseous.
Explanation:
For the reaction:
C₂H₅OH(l) + 3O₂(g) → 2CO₂(g) + 3H₂O(l)
The ΔH is -1.37×10³ kJ. As the change in enthalpy is <0,<em> II. The reaction is exothermic.</em>
The ΔH formation of a compound is different if the chemical is in liquid or gaseous phase. For that reason: <em>III. The enthalpy term would be different if the water formed was gaseous.</em>

Real quick, I will tell you why i think it does from a scientific point of veiw, but I dont know for sure.
The reason that the Earth goes through so much change on a regular basis is because of Gravity. What Gravity is doing is pulling objects to the Earth that it can reach (Which you probably knew) and so when it does this, it is pulling at the earths surface as well, causing constant change.
I hope this helps you!
