A compound sentence needs at least two independent clauses and can be combined by conjunctions such as and, or, but, for, yet, nor and so.  The independent clauses can also be combined by a semicolon ;
(A)
If we look at A, we can see A does not have two independent clauses. There is a depend and an independent clause and that is why we have a comma after go in A.
(B)
What I said about A is the same for B
(C)
Ah! good old C. C has two independent clauses and has the conjunction and after mall and before John. This is very important because this is where one independent clause stops and another independent clause starts. C has everything that makes up a compound sentence so the answer is C.
(D)
If we look at D, we can see D is just a single independent clause, which is asking a question.

Answer:
Convection current 
Explanation:
Convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air, the cold air due to its greater density moves downward, and the cycle continues, this upward and downward movement is called convection current. 
 
        
             
        
        
        
Answer:
Complete Subject= New Tropical Wave
Simple Subject= Wave
Explanation:
 "A complete subject is the simple subject, or the main word or words in a subject, along with any of the modifiers that might describe the subject."
Basically something like "wave" would be a simple subject because its not giving all the info about the wave, just that it is a wave. Whileas a complete subject would be "New tropical wave" because we were given all the info about the subject, making it complete.
