How to Approach Expository Writing

Cause and Effect

As you look at the picture below, think about what we call this design of nature. Of course, this is a desert. If someone asked you what caused the desert to have the features that it does, what would you say? Most of us would agree that the hot sun and lack of water helped to cause the dry conditions that resulted in the formation of a desert.

When you answer the question, "why?" in your writing, you are using the process of cause and effect. You can explain something logically by showing how one action results in something else. Finish this sentence:

The last type of structuring to be discussed in this lesson is explaining a process. You do this when you show a person how to do something. You must tell the procedure step by step. Think about how you would survive in the desert if you had to. Let your mind think about the things you would need to do to protect yourself.

To survive in the desert…

Cause and Effect:


In this lesson, we have discussed how to write with a specific type of structure. When possible, determine the method after selecting the topic. However, many times you will write the rough draft and then decide what type of structure will work best. You can always go back and make revisions later.
