Volcano Eruption
Last Tuesday, a special conference concerning volcano eruption was held with experts from South and North Korea. A topic of the conference was 'Possibility of Volcano Eruption in Mt. Baek-Du, N.K.' and it was held due to the request from North Korean government. According to the recent news, there were some signs indicating volcano eruption in Mt. Baek-Du such as a rise of the ground and geothermal heat. It means that a volcano eruption becomes more real than ever. What makes volcano erupt? What is the process of volcano eruption? To understand indicators happened in Mt. Baek-Du, these questions would be helpful.
First of all, there are two conditions for volcano eruption: weak surface of the earth and magma. The most well-known weak surface is the place bumping two (or more) plates each other. Since there is a big crack, it is much easier for magma to burst outside the surface. Mt. Everest is a good example because the mountain rose (still, rising) as Indo-Australian plate bumped into Eurasian plate. Besides, there are naturally weak crusts without the plate activity. This is because there are some powers stretching and loosing the plates like contraction and relaxation of muscles. The next condition is magma. Magma is created because of inner energy of the earth and friction between plates. It is hot liquid with gases. The longer and more magma are under the surface, the more possibility of volcano eruption can be.
If there is a place with weak crust and magma, magma will be lifted along the crack. The reason why magma rises is that the liquid is much lighter than the ground. In the process, the ground presses magma not to rise anymore, and the pressure makes the liquid have gas bubbles. You can imagine a coke bottle after you shake the bottle. As the coke hit the bottle and lid, coke will make bubbles. While gas bubbles are created under the surface, there appear some indicators warning volcano eruption. There can be frequent earthquakes and some waterholes are boiling. Sometimes, smoke comes out of the ground.
As more and more gas bubbles hit the weak surface of the planet, there comes the time that the crust cannot withstand. With a huge sound of eruption, the volcano will eventually burst. Rocks and ashes will be thrown into the sky and lava will flow and cover the land. It is as if the coke bursts with the soda and gas when you open the lid after shaking the bottle. The volcanic activity will gradually stop when all gases and bubbles escape out of the surface. The time will vary depending on the status of volcanoes. That is why the volcanoes are classified into three types; an active volcano, a dormant volcano, and an extinct volcano.
Currently, the movement of Mt. Baek-Du is unusual. There are many news covering extraordinary signs around the mountain. Researchers found that there was a rise on the ground and some trees and plants withered due to the geothermal heat. Also, there are about every 250 earthquakes a month after 2006. Some experts predict there will be big eruption in five years. Even though Mt. Baek-Du is located in North Korea, it can affect our life a lot. We need to inspect the status and prepare what we can do before the disaster.
I think you did reasearch pretty well! The hook which was consisting of latest news about Volcano was good! It was so natural and interesting.
ReplyDeleteOne thing I found to suggest it ..
The reason why magma rises is that the liquid is much lighter than the ground.
I think you'd rather use Because instead of That.
And to improve your writing, I would suggest that the conclusion is kinda weak I think compared to the other paragraphs. Think about that when you revise your writing !
Nice work !
