Good morning dear, back again on my blog. Today we will continue the Explanation Text material. Check out the following explanation. In this part II, I will give some examples of Explanation Text.

General Statement

We all know that tsunamis are a series of destructive waves and powerful. Tsunami is the deadliest wave because the wave speed is incredibly fast. But do you know how a tsunami can happens?

Explanation

Tsunami originated from Japan, “tsu” meaning harbor and “nami” meaning wave. They are normally caused by landslides, earthquakes, volcanic eruptions in, or close to an ocean. After some sort of underwater disturbance, this causes energy to rise up to sea level pushing the water high into the air. Gravity kicks in and pulls it down again and then consequently causing the water to filter out into many different directions.

When a tsunami begins to approach the shore the energy in the wave is compressed. As a result, the water is pushed up into the wave, resulting in a powerful tsunami. If the trough hits the shoreline first, it then causes the tide to drastically retreat.

Conclusion

So, tsunamis happen because of natural disasters such as earthquakes or volcanic eruptions. People who live near the shoreline have to be careful because they are threatened by tsunamis whenever there is an earthquake.

Why Eiffel Tower Was Built

If we talk about the Wonders of the World buildings, then we will see Eiffel Tower as one of them. However many of us do not know the tower’s past history on why it was build. Everything has the reasonable background, especially for the tower which is to be one of the most recognized buildings in the world.

Primarily, the Eiffel Tower was built for the World Exhibition. It was called Paris Exposition in 1889. The exhibition was organized to celebrate the 100th anniversary of the French Revolution. The purpose of building Eiffel Tower in such structure was to show to the world France’s advancement of technology and beauty. The Eiffel Tower was designed by Gustave Eiffel. It seemed that then the name of the tower was derived from the designer’s last name, “Eiffel”.

Another reason on why the tower was built was for scientific progress. Although few realized it, the Eiffel Tower would become the prominent structure in terms of science and technology. Many experiment with temperature, pressure and pendulums were performed atop the unique famous building. Additionally the Eiffel Tower was used for radio transmission tower. Many experiments were conducted atop the Eiffel Tower for radio transmission advancement. Once the Eiffel Tower was proposed to be demolished but it was spared because the tower had the promising future as a radio tower.

Mammatus Clouds

Mammatus comes from the Latin mamma which translates to “udder” or “breast”. Their striking appearance is most visible when the sun is low in the sky and their pouches are framed by the sunlight. This supplementary feature is a firm favourite with many meteorologists as well as cloud and photography enthusiasts.

Mammatus clouds are some of the most unusual and distinctive clouds formations with a series of bulges or pouches emerging from the base of a cloud. The shape of mammatus formations can vary widely; from the classic protruding shape, to a more elongated tube hanging from the cloud above.

Mammatus clouds are usually formed in association with large cumulonimbus clouds. Typically, turbulence within the cumulonimbus cloud will cause mammatus to form, especially on the underside of the projecting anvil as it rapidly descends to lower levels. This reverses the usual cloud-forming process of upward growth, making for an uneven cloud base.

Mammatus often forms in association with Cumulonimbus clouds, which in turn bring thunderstorms due to their huge mass of unstable air. Mammatus cloud generally form in the most unstable cumulonimbus, meaning that there is also a chance of hail, heavy rain and lightning in the vicinity, and if the air is cold enough during winter they can produce snow. Sometimes mammatus may form on other cloud types which produce no rain, though this is far less common.

Mammatus usually form on the base of a cumulonimbus anvil, but they have also been sighted to form on other cloud types, such as stratocumulus, altostratus and altocumulus. Mammatus have also been observed to form on the underside of volcanic ash clouds.
