<span>The question is asking us "Which of the following would be a result of increased solar activity?"
The Sun is extremely hot, and when it is warm on Earth, the heat has as it source in the Sun. Therefore, an increased solar activity would mean increased temperature on Earth - longer summers and shorter winters, and warmer sea temperatures. The best answer is :
B. Warmer-than-normal sea surface temperatures </span>
        
                    
             
        
        
        
I think answer is
C. Something that can be observed or measured while changing the identity of the substance
        
                    
             
        
        
        
I'm not sure but I think it is A. image one has the most spread out particles like a gas, and b has closer together particles like a liquid or solid. since there are no choices that say A=gass and B=solid, so I am guessing it is answer A.
