Final answer:
Mendelssohn likely uses a thick, homophonic texture to depict the aggression of the weather in 'storm' passages within his compositions, capturing the intensity and power of a storm in line with the Romantic era's dramatic expression.
Step-by-step explanation:
In Mendelssohn's composition, he portrays the aggression of the weather, particularly in 'storm' passages, through a specific musical texture. Among the choices given, it is reasonable to suggest that Mendelssohn employs a thick, homophonic texture to depict the stormy atmosphere. This textural choice creates a dense sound, where multiple lines of music move together rhythmically, conveying the power and intensity associated with a storm. The use of such a texture aligns with the Romantic era's tendency to express human emotions through dramatic and powerful musical expressions.
