Answer:
c. Water changes form, but the total amount of water remains the same.
Explanation:
Hello,
Conservation of matter explains how once either a chemical or a physical change or process is done, the initial amount of matter MUST be equal at the beginning and at the end of the process.
Water cycle is such a relevant example as long as the water changes from liquid to vapor due to environmental conditions which promote such change and vice versa but the initial amount is equal to the final one if no water is added or withdrawn from the considered system (ecosystem).
Best regards.
