There are three main forms of writing that authors can use to display their purpose within their work. What are these three main forms of author's purpose, and what is a good acronym to help you remember them?

The acronym to help you remember the three main forms of author's purpose is P.I.E. Authors can create texts that are intended to persuade you - some examples of persuasive writing would be speeches, advertisements, personal blogs, reviews, or editorials. The purpose of this form of writing is to get the reader(s) to change their mind about something. The next form of writing is informative - here the author is trying to provide the reader with new information. Some examples of this form of writing are autobiographies, science or history books, and instruction manuals. The last form of writing that authors can use is entertainment. Here the sole purpose of the writing is to entertain the reader. Examples of this writing can be found in several fiction books, magazines, and plays.

List the four layers of the Earth and give a brief description of their function?

The innermost layer of the Earth is the inner core. It is a solid ball that is made up of iron and nickel. Next is the outer core which is also made up of mostly iron and nickel, but unlike the inner core, the outer core's metals are melted into a hot liquid that allows for movement around the inner core. The mantle is a rock-hard layer and is the largest of all the layers. Although the mantle is rock-hard, parts of this layer become hot enough to liquify and become slow moving molten rock or magma.

The purpose of research in the field of psychology is to make connections through thinking about what we do, observe the relationships between certain behaviors, and then explain a possible cause for those said behaviors or connections. Is it fair to say that we try and "prove" these behaviors or acts in psychology?

False. In psychology, we try our hardest to avoid the use of the word "prove." You cannot state that something is proven, because this would be claiming that for every single situation or observed behavior A would automatically cause B. This would lead to bad psychology because human behaviors are unpredictable and cannot necessarily be proven as total truth across the board. We state that the findings/observations can be related, or that the research revealed similar findings as other research, but we must try and refrain from using the word prove in psychology.
