In a world of reports and recounts, chronological and non-chronological, it can be very easy to get the different text types mixed up. If you're tasked with the challenge of writing an explanation text, you will need to be ready to talk about one aspect of the world in detail. In a simple non-chronological text, the author is required to tell us about an object or an event in no particular time order. In a piece of instructional writing, it is very important that the instructions are given in order. In an explanation text, something needs to be described with some order to it- not because it is critical but because it just makes sense. The most common form of explanation text is one where you explain how something works, how to do something or why something happens. For example, you might explain why it rains, why the sky is blue, what the samba is and so on.
