Actually, creating a thesis and defending it typically falls under the realm of argumentative or persuasive rather than descriptive writing.
When you create a thesis statement, you are presenting a claim or an argument that you will support throughout your essay or research paper. This thesis statement serves as the main idea or central argument of your work.
In the following sections, you will then use evidence, logical reasoning, and persuasive techniques to defend your thesis and convince your reader of its validity. This involves presenting arguments, counterarguments, and providing evidence to support your claims.
Descriptive writing, on the other hand, focuses on providing detailed descriptions and sensory details about a topic or subject. It aims to paint a vivid picture for the reader through the use of imagery and language.
While both descriptive and argumentative writing have their place in academic and professional writing, the act of creating a thesis statement and defending it is associated more with argumentative or persuasive writing.
