Each star on the map represents location of an epicenter. Thus, the correct answer is Option A.

<h3 /><h3>What is an epicentre on the map?</h3>

Epicenter is defined as the point directly at the position on the Earth's surface, where the earthquake started. These are represented by the stars on the map.

Scientists use triangulation to find the epicenter of an earthquake.

When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects.

Every earthquake is recorded on numerous seismographs located in different directions.

Thus, the correct answer is Option A.

Answer:

Option A and D are correct.

Unstable species react rapidly.

Stable species do not react rapidly.

Explanation:

The complete question is attached to this solution.

The more stable a reactant is, the less reactive it will be. A stable reactant has a very stable structure in which it will avoid any perturbations. And for a reaction to occur, the bonds in the reactant must break down to form the products. A stable reactant has very strong bonds that aren't easy to break down, hence, reactions involving very stable reactants do not proceed rapidly.

And the more unstable a reactant specie is, the more rapidly it reacts. This is why the reaction involving the less stable isotope of carbon; Carbon-14 is very rapid. It is the same reason as explained above that is responsible for this. The bond between unstable species are not strong and are easily breakable, thereby leading to a quick reaction.
