Layers of rock that bend can produce a downward fold known as a(n)

Layers of rock that bend can produce a downward fold known as a syncline. 

This is the type of fold that occurs with the younger layers of rocks remaining closer to the center of the structure. Synclines can be recognized by the fact that the youngest layers of rocks always remain near the folds center.  

Hope this helped..

Syncline

Explanation:

Synclines are the down folds that are constructed due to the compressive forces acting on a layer from both sides. It usually occurs in size ranging from a microscopic scale to a large megascopic scale. The oldest rocks are present at its outermost limb and the rocks become gradually younger toward its hinge area.

In an outcrop, the syncline and the anticline, both form simultaneously. The limbs that dip towards the trough of the fold indicate a syncline whereas the limbs that dips towards the crest are the anticline. The variation in the shape of these foldings (anticline and syncline) depends upon the intensity of the force.

The correct option is B.
This question is testing your knowledge of the differences between solid and liquid particles. The particles of the solid vibrate around a fixed position, they can not move about while those of the liquid are able to move to some extent. The candy in Damien's pocket melted because it was heated up by the temperature of his body. Because the particles of the chocolate has been heated, they gain more kinetic energy and they vibrate faster compare to that of the solid chocolate.
