Page 7 Key Concept: Responsibility Volcano’s Weak Spot Have you ever wondered what life would be like if a volcano erupted in your home town? Well let me walk you through the steps of its destructive power. Also the good and some bad things that come from a volcano eruption! The earth has two types of crust. Oceanic is thiner than continental crust, which brings me to my next point. Continental crusts formed from granite rock, which is formed by volcanic action . There are three types of volcanos. They are dormant, extinct, and active. Active means a volcano erupted or is erupting. Dormant means a volcano is sleeping, but is not extinct. Extinct means a volcano has not erupted in hundreds of years, and is not expected to erupt again. Mount St. Helens was thought to be extinct, but it was really a dormant volcano, so many died. As lava comes out of a volcano it can not be stopped, but it does come out slow, and water makes it slower. http://environment.nationalgeographic.com/environment/photos/volcano-general/#/volcano19- iceland-lava-steam_22345_600x450.jpg Igneous rock forms when molten rock and magma cools and then hardens. That is what makes an igneous rock. Metamorphic rock is when heat and pressure gets on a rock, it forms a metamorphic rock . Also pillow lava is actually not a normal type of lava. This is a special kind of lava. It’s name is pillow lava. It can go above cracks in the earth and still continue and not stop until it losses power . Also a volcano can cause a wild ﬁre and tsunami, when the lava and molten rock hit the sea. Since it moves at such high speed once it hits the sea it is going to make a huge wave. It makes a wild ﬁre when the molten rock and the lava hit the grass. It will start a ﬁre. It will get big and eventually be called a wild ﬁre. http://environment.nationalgeographic.com/environment/photos/volcano-general/#/volcano19- iceland-lava-steam_22345_600x450.jpg The Perspective of Others I want you to think of someone who was where a volcano erupted. How would you feel? Yes I know you’re wondering. There’s no volcanoes in America, but what if more volcanoes erupted making a new one in America. Volcanoes can be good and bad. I am going to tell you the good that comes. I will tell you about the time a volcano eruption saved the world. It was freezing all around the world, then a volcano erupted saving the earth from it’s endless winter. It did this by releasing tons of carbon dioxide into the sky. Then hundreds of years later the world slowly but surely started to heat up. Then the world started to slowly turn back to normal. This saved the world because so many natural disasters occurred, such as tornadoes, hurricanes, avalanches, blizzard, thunder, lightning, and tsunamis. This saved the world because we started to produce our own heat, then the sun came. I know this is a very sad moment for us, but it was the end of an endless winter and the beginning of a new summer. This is the perspective of those who where hit by the iceberg hundreds of years ago. http://environment.nationalgeographic.com/environment/photos/volcano-general/#/volcano05- smoke-lightning-iceland_22332_600x450.jpg Volcanoes Change the World What is pillow lava? Pillow lava is lava that can form above cracks, and can do this very easily. But it is still the same as normal lava, but just a bit cooler and better . What is a summit? A summit is the top point of a volcano, where the lava comes out to destroy that part of the world. How long does it take for a volcano to touch the ground? Well, that’s pretty easy. If you ask me how long does it take volcanos to erupt and touch the ground, the answer is we can not be sure how long it takes. The reason of this is there are various types of volcanoes that take different amount of times for every eruption. So nobody knows, but they destroy the earth with their lava. http://environment.nationalgeographic.com/environment/photos/volcano-general/#/volcano05-smoke-lightning- iceland_22332_600x450.jpg Other’s Responsibility The responsibility of volcanologist is to know when the volcano might erupt. So we can escape and go to a safer place, they should know before hand, but sometimes they just can’t. Okay now you will learn what are geologist jobs. They are very much like many other scientist, but very different. These type of people study the earth, so can sometimes help many others types of scientists in their studies. I hope you learned a lot about volcanos and what they do to kill and also help us in our lives. 3 http://environment.nationalgeographic.com/environment/photos/volcano-general/#/volcano01- mount-semeru-indonesia_22328_600x450.jpg About the Author Ajith loves to play video games.
