Definition and purposes of Explanation
Explanation is a text which tells processes relating to forming of natural, social, scientific andcultural 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.
Generic structure of Explanation
General statement; stating the phenomenon issues which are to be explained.Sequenced explanation; stating a series of steps which explain the phenomena.

Contoh Explanation Text
The Process of Rain
Water in the earth is kept in many places like the ocean, the ocean, the river and the lake. Butdon’t be wrong, the plants leaves and the land also kept water.Each day, this water will evaporate with help of the sun. The process where water evaporatesfrom plants is called transpiration. Afterwards the vapour will experience the process of condensation where the vapour will condense and turn into a cloud. The form of the cloudalways changes according to weather conditions.The clouds will move to different locations with the help of wind that bellows vertically or horizontally. The movement of the vertical wind results in the cloud forming big ‘lumps’.After that, the wind increases the size of the cloud and each cloud will overlap. Finally thecloud will reach the atmosphere that has a lower temperature. Here the particles of water andice is formed.Eventually, the wind can not support the weight of the cloud and so the cloud that is full withwater will experience a process called precipitation or the process where rain or hail falls toearth.

Contoh Explanation Text
Why Summer Daylight is Longger than Winter Daylight.
In the summer, the amount of daylight that we get is more than we get in winter. This is not because as much people think we are closer to the sun but because of the tilt of the earth.The earth is actually closer to the sun in winter than it is in summer but you would beforgiven for thinking that this can not be true after looking out of your window on a cold andfrosty morning.It seems strange that as the earth get closer to the sun during its orbit then the amount of daylight that we get decrease. But that is the case. It is the tilt of the earth that determine theamount of daylight that we get and so the length of time that for us the sun is above thehorizon.
