Definition of Explanation Explanation is a text which tells processes relating to forming of natural, social, scientific and cultural phenomena. Explanation text is to say 'why' and 'how' of the forming of the phenomena. It is often found in science, geography and history text books. Social Function To explain the processes involved in the formation or working of natural or sociocultural phenomena. Generic structure of Explanation 1. General statement; stating the phenomenon issues which are to be explained and to position the reader. 2. Sequenced explanation; stating a series of steps which explain the phenomena. 3. Closing ; Language Features 1. Using Simple Present Tense E.g : The earth is actually closer to the sun. 2. Using action verbs E.g : 3. Using passive voice E.g : You would be forgiven by me 4. Using noun phrase E.g : 5. Using adverbial phrase E.g : 6. Using technical terms E.g : 7. Using general and abstract noun E.g : sun, rain 8. Using conjunction of time and cause-effect. E.g : because, so, this causes (cause-effect conjunction) then, next, later ( conjunction of time ) Significant Lexicogrammatical Features Focus on generic, non-human Participants Use mainly of Material Processes and Relational Processes Use mainly of Temporal and causal Circumstances and Conjunctions Example of Explanation Text Tsunami The term of “tsunami” comes from the Japanese which means harbour ("tsu") and wave ("nami"). A tsunami is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale. A tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Such large vertical movements of the earth's crust can occur at plate boundaries. Subduction of earthquakes are particularly effective in generating tsunamis, and occur where denser oceanic plates slip under continental plates. As the displaced water mass moves under the influence of gravity to regain its equilibrium, it radiates across the ocean like ripples on a pond. Tsunami always bring great damage. Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area. Generic Structure 1. General Statement 2. Sequenced Explanation 3. Closing Text of Tsunami It is a statement which says about tsunami and how it is happen.
