The distribution of across the globe provides the primary indicator of boundaries between all tectonic plates.

The distribution of earthquake across the globe provides the primary indicator of boundaries between all tectonic plates. Earthquakes have a definite distribution pattern. There are three major belts in the world which are frequented by earthquakes of varying intensities and these belts are as under the circus pacific belt, mid Atlantic belt and mid continental belt. 

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
