heyy.. today i want to tell u the example about explanation text

i hope u guys understand and enjoy...💓

EXPLANATION TEXT

WHAT IS AN EXPLANATION TEXT?

“Explanation texts are frequently incorporated into other texts, used to provide information which answers questions of interest on that topic”An explanation text tells your audience how something works or why something happens.

Explanations detail and logically describe the stages in a process, such as the water cycle, or how a steam engine works.  Other examples could be how a law is made, or why we blink when we sneeze.

There are three types of explanations.

• Causal - Details what causes the change from one stage to the next ie: How a president is elected.

• Theoretical - Details the possible phenomena behind a natural or created process that is not fully understood. eg What caused the Nazi's to lose World War II.

• Factorial and consequential explanations explain effects and outcomes of processes. They are more commonly used in upper primary and secondary contexts. For example:

  • Scientific– eg Explain the causes of climate change (Factorial)

  • Historical– eg Explain the causes of World War 2 (Factorial)

An explanation text is similar to a procedural text, and these can often be confused, however an explanation text explains the how and why behind a process  such as  

• What causes a Tsunami?

• Why are our rain forests disappearing?

• The process of making aluminum.

• A procedural text is generally instructs how to make or do something such as recipe.  Although they appear similar they are very different when compared side by side

• Rainbow

Rainbow is one of the optical phenomenon that occurs naturally in the earth’s atmosphere. Physically, the colors commonly identified from the wavelengths. For example, the red color has a wavelength of about 625-740 nm, and blue around 435-500 nm. Set of colors that are expressed in wavelengths (usually symbolized by λ) is called the color spectrum. These colors are components of white light called visible light (visible light) or waves appear. Other components are not visible light (invisible light), such as infrared (on the right in red) and ultraviolet (on the left orange). White light that we usually see (also called visible light or visible light) consists of all components of the colors in the spectrum above – of course there are other components that are not visible, so-called invisible light.

The simplest tool that is often used to decipher the white color is a glass prism. A glass prism decompose white light coming into components of light. The prism of this nature not only can decipher light. Besides. Water droplets of rain is one example of the items available in nature that could decompose white light. When a beam of white light on a drop of water, these water droplets behave like a prism. He described the white light was so created the colors of the rainbow. A drop of water behave like prisms when receiving a beam of white light. Light is partially reflected towards the observer, some are forwarded. The colors in the rainbow-like blocks wide because we only see one color to the water droplets. Described sunlight by water droplets A only up to our eyes in the red color wavelength. Meanwhile, water droplets and provides a wavelength purple. Droplets of which give each one wavelength on our eyes. So in the end the viewer see a complete rainbow colors.

Rainbow usually occurs when rain or drizzle after heavy rain stopped. After the heavy rain stopped, the air filled with the vapors of water. Moreover, the rainbow can be created in a puddle of oil. Sometimes in certain circumstances, a beam of white light enveloped by a rainbow. Rainbow can occur anytime and anywhere in the home involves three well as the nature of light, the reflection (reflection), refraction (refraction), and diffraction.

We can only see a maximum of a half circle rainbow. To see the full rainbow of the circle, then we must stand on higher ground.

The illustrations in the picture above shows that the circular rainbow. It is true that the rainbow circle, instead of a parabola as some people. On the ground, we only see a maximum of a half circle rainbow. If we stand on the rain, for example, on an airplane, then we could see a rainbow circle intact. This is all caused by the optical geometry in the process of decomposition of color. With this optical geometry also we can explain the straight line that passes through our eyes and the sun also passes through the center point of the circle rainbow. Because rainbow created involving distance observer with water droplets, then the rainbow always move to follow the movement of the observer. It makes our distance with rainbow constant (same), in other words we could never approach the rainbow.

i think thats it, hope u enjoy
