Which of the following is true of water in earth's atmosphere (choose all that apply)? leaves the atmosphere via precipitation and enters the atmosphere via evaporation exists as vapor, liquid, or solid in the atmosphere in gaseous form, is the most abundant variable atmospheric constituent its atmospheric concentration is constant in both space and time releases large amounts of latent heat when changing from vapor to liquid changes from liquid to vapor via condensation does not play a significant role in the atmospheric greenhouse effect

a. i. only is correct.

chinese civil war took place over a long period of time between 1927 and 1950. the war was interrupted when japan invaded china in 1936 and by world war ii. the war was fought between the nationalist government of china, also called the kuomintang (kmt), and the communist party of china (cpc). 

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
