What role does the description play in the novel?how to write a thesis based on the story ?

Description/Narration builds the very novelistic fabric. A
novel usually tells a story, portrays characters, presents the setting, evolves an
atmosphere, works out a philosophical attitude to life. In every field,
descriptive/narrative art of the novelist is called into service. The setting has to be
described with necessary details so that it suits the growth of the novel's plot.
Description of the characters-- their appearance/exterior as well as their
minds/motives/interior--constitute a crucial part of the novel's unfolding pattern. An
episode/action/event involves appropriate descriptive skill. Authorial comments and
philosophical reflections also depend upon descriptive art. A work of prose-fiction is
chiefly grounded in the author's excellence in description/narration. It is obviously
much more than mere mechanical accumulation of
information/detail.
