This article is about what makes volcanoes erupt. George Garza also talks abut famous eruptions and what the difference is between a active and dormant volcano. He has some interesting points in his article that I didn't know. For an example is about how a volcano formed in just nine years to a 1400 foot volcano. According to George volcano's are formed from movements of tectonic plates. The shift of them can cause fissures to appear. In which volcano's slowly start to grow.
How does an eruption work? I read this article by George Garza it states that the movement of tectonic plates causes the upward push of volcano's and the opening of fissures in the earth. The earth has a source of natural radioactive decay. This radioactive decay is what causes the melting. In order to have an eruption you need to have pressure and gas built up inside the chamber of the volcano. You can get gas and pressure build up when the magma inside the chamber cools down it releases gas. Which in turn can cause the eruption of the volcano. My understanding of a active volcano is one that still has magma or smoke and ash coming out. A dormant volcano is one that has zero activity in the past few years.
One thing I'm so curious about is how a volcano formed to 1400 feet in just nine years. In my mind that seems nearly impossible just due to the fact whenever you drive around the earth always stays the same. One thing I never knew about eruptions is the build up of gas. I knew about the pushing together of the plates causes pressure and eruptions, but I never knew about the gas build up.
I would like to know a more detailed explanation about how the volcano formed to 1400 feet in just nine years. How does magma reach such high temperatures? I think about some volcano's that are in cold areas yet the magma is still at extreme temperatures. What keeps the temperature of magma so high? What makes a volcano like Mt. Saint Helen's erupt at such at weird angle? Maybe its due to the offset of balance of gas? Volcano's can be fascinating there almost unpredictable as to what they are capable of.
Hi Tim:
ReplyDeleteGood work finding this source. I gave it a look over at catalogs.com and it provides a good overview of the science underlying magma flows. At the same time, I appreciate your detailed synopsis of the article.
In your free-write, you talk about being curious about where the Discovery Center is from and how they first started. I'm wondering if another potential avenue for inquiry might be why they first started? During your orientation, you might discuss this. I'd also be curious to see if you could tie your interest in volcanoes (which are nice) in to the Discovery centers approach unpacking the science that underlies them.
A big part of researched writing is framing why you decided to pursue particular routes of inquiry, so as to better facilitate your readers understanding of your approach. You aren't quite at the stage where you'll have to do this yet, but keep it in mind as you continue with your exploratory (background) research. The best researchable topic-areas have immediate relevance for outside audiences, intersect with the conversations other people are having, etc.
Hey Tim, this is my informal reply, so here goes.
ReplyDeleteFirst, your source is a little difficult to access. You only listed the main website, catalogs.com, not the address for the specific article. This makes it more difficult to find your source, so be sure to add the entire address for the specific page your source is on. On to the post itself. I thought you found an excellent article and topic. These are very interesting facts about volcanoes, and really does make you wonder about how it happens. I felt this really ties in to what the Discovery Center is all about, making this an excellent topic. You summed up the article well, and in expressing your own thoughts, its clear the article really did inform you and make you wonder. I also thought you had excellent questions, taking the article and expanding it, wanting to know more of the details about the different aspects behind a volcano eruption. This shows how the article sparked an interest in you to find out more, similar to how the Discovery Center should work, sparking an interest in kids to learn more.
