EXPLANATION TEXT
Definition
and purposes of Explanation
Explanation is a text which tells processes relating to forming of natural, social, scientific and cultural phenomena. Generally the purpose of an explanation text is explaining how something forms or why the thing happens. So when we read an explanation text, the text will cover the answer of "how" or "why" relating to a thing or a phenomenon. It is often found in science, geography and history text books.
Generic structure of Explanation
General statement; stating the pheno
menon issues which are to be explained.
Sequenced explanation; stating a series of steps which explain the phenomena.
Language Feature of Explanation
Featuring generic participant; sun, rain, etc
Using chronological connection; to begin with, next, etc
Using passive voice pattern
Using simple present tense

How a Plane
Flies
Today, Everyone must see a plane flying. Even Some of the people have flown with an airplane.
Have you ever thought why this heavy metal object can be lifted in the air? How
can the airplane fly?
An airplane flies because it can generate a force. The force is scientifically called Lift. It normally moves that heavy airplane upward. So, how does the Lift happen? Well. Lift occurs by the generating of the forward motionof the airplane through the air. please note that this motion of the airplane is produced by what we call the Thrust of the engines.
There are four forces which act on a flying airplane. They are Thrust, Lift , Drag and Weight. How do these four forces work? When the Thrust which is produced by the engines is greater than the force of Drag which is produced by the resistance of the air, the airplane will moves forward. When the forward motion is enough to produce a force of Lift which is greater than the force of Weight, the airplane will moves upward.

How Earthquakes Happen
Earthquake is one of the most destroying natural disasters. Unluckily it often happens in several regions. Recently a horrible earthquake has shaken West Sumatra. It has brought great damages. Why did it occur? Do you know how an earthquake happens?
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves. It make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs.
During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus is called the epicenter of the earthquake.
