Answer: Infrasound because sound waves travel easily through water to accessible buoys.
Explanation: its installation: underwater microphones hung from buoys near a volcano. how it works: senses low-frequency sound waves near a volcano. Since in its installation it specifies that it has UNDERWATER microphones and the question asks in predicting an eruption from an UNDERSEA volcano, that makes perfect sense.
Answer:

Explanation:
Answer:the quality or character of being periodic; the tendency to recur at intervals.
"the periodicity of the sunspot cycle"
Explanation:
Answer:- The answer is .
Explanations:- Negative value of delta G indicates a spontaneous reaction. From Gibb's free energy equation:
From this equation, delta G is more negative if delta H is negative and delta S is positive.
If the entropy is increasing then it means delta S is positive but just by looking at the delta S, we can't say if delta G is negative as delta H and temperature also plays an important role.
So, the only right option is + delta S.
