Definition of Explanation Text

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.

Generic Structure of Explanation Text

  • General statement.

Stating the phenomenon issues which are to be explained.

  • Sequenced explanation.

Stating a series of steps which explain the phenomena.

The Characteristics / Language Feature of Explanation Text:

  • Featuring generic participant; sun, rain, etc
  • Using chronological connection; to begin with, next, etc
  • Using passive voice pattern
  • Using simple present tense

Example

How does Rain Happen?

Rain is the primary source of fresh water for most areas of the world, providing suitable conditions for diverse ecosystems, as well as water for hydroelectric power plants and crop irrigation.

The phenomenon of rain is actually a water circle. The concept of the water cycle involves the sun heating the Earth’s surface water and causing the surface water to evaporate. The water vapor rises into the Earth’s atmosphere. The water in the atmosphere cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation which can be in the form of rain or snow.

However, not all rain reaches the surface. Some evaporates while falling through dry air. This is called Virgo, a phenomenon which is often seen in hot, dry desert regions.

110108-Tsunami

A tsunami (from Japanese: 津波, “harbour wave”;[1] English pronunciation: /suːˈnɑːmi/ soo-NAH-mee[2] or /tsuːˈnɑːmi/[3]) or tidal wave,[4], also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.[5] Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.

Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer.[6] Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide.[7] For this reason, it is often referred to as a “tidal wave”, although this usage is not favoured by the scientific community because it might give the false impression of a causal relationship between tides and tsunamis.[8] Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called “internal wave train”.[9] Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins. The 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history, with at least 230,000 people killed or missing in 14 countries bordering the Indian Ocean.

The Ancient Greek historian Thucydides suggested in his 5th century BC History of the Peloponnesian War that tsunamis were related to submarine earthquakes,[10][11] but the understanding of tsunamis remained slim until the 20th century and much remains unknown. Major areas of current research include determining why some large earthquakes do not generate tsunamis while other smaller ones do; accurately forecasting the passage of tsunamis across the oceans; and forecasting how tsunami waves interact with shorelines.

Making Paper from Woodchips

 

Do you have any paper in your bag? It may seem like a silly question but do you know how to make paper? What is paper made of? Right! And how is about ‘wood chipping’? Have you ever heard about it? Well, wood chipping is a process used to obtain pulp and paper products from forest trees.

First of all, the tops and branches of the trees are cut out and then the logs are taken to the mill. At the mill the bark of the logs is removed and the logs are taken to a chipper which cuts them into small pieces called woodchips. The woodchips are then screened to remove dirt and other impurities. Hmm … at this stage they are either exported in this form or changed into the pulp by chemicals and heat. Oh, I almost forgot, the pulp is then bleached and the water content is removed. Finally, the pulp is rolled out to make paper.

Considering the complexity of making paper, let’s appreciate any paper on our hands. Use it more effectively. Thank you for listening. Bye.
