A large area undergoes the same amount of metamorphism. All rock reach the same metamorphism grade. However, after the metamorph
Mrrafil [7]

The only explanation in this situation is that the parent rocks of the marble and slate were different. This indicates that the region once held both shale and limestone before metamorphism.

In reference to rocks, it denotes those that have undergone metamorphism—rocks that may have started as sedimentary, igneous, or another type of metamorphic rock but has since undergone "recrystallization" and taken on an entirely new form—under new temperature and pressure conditions.

For instance, when limestone is heated and compressed, it changes into marble, a more coarsely crystalline and occasionally banded rock.

When shale, a clay-rich, soft rock, is compressed, slate, a tougher rock, is created.

The alterations are frequently even more remarkable, resulting in the formation of new minerals, including garnet, mica, and tourmaline (as seen in schist).

As you may know, people’s physical and emotional health interact: One can affect the other. The characters in "In Another Countr
Margaret [11]

Answer:

To preserve their mental health, the characters must keep in mind that all suffering is temporary and although it is difficult, they will overcome this situation. What can help characters deal with their situations is by reasoning about the following questions:

"What led me to this situation?"

"What are my limitations in dealing with this type of problem?"

"How could I have acted to minimize the impacts of suffering?"

"Would any action by me prevent these disorders?"

Explanation:

Every time that the characters evaluate themselves and correct their behaviors, they will be able to follow the emotional evolution that will help them to deal with all their suffering. In this journey, each one has a different rhythm. In fact, we are different in almost every aspect of our physical and mental makeup. The variations in intelligence are enormous and also those related to aggressiveness, intensity of fears and the ability to deal with them. It would not be fair, therefore, to tell a character (or a person) that he is suffering from "nonsense". What is small for one may be large for the other. Underestimating the pain of others is not synonymous with help, but a lack of empathy.

We do have a duty and obligation, in the name of our own well-being, to try to get rid of our pains as quickly as possible, but that does not mean not feeling them. Some people do it more easily, while others "fall in love" with the problem and think about it in a recurrent and obsessive way. They silence the word, but the mind goes on chattering.
