Gemma Tarlach author of the article “Twenty Things You Didn’t Know About Lava” that I found from the magazine Discover did a very nice job talking about lava and the variations of it. Although she’s not a full-blown geologist she did a nice job with information very close to that of what’s been inscribed into our text books and what’s been told to us in class. After reading the article I did some research on Gemma Tarlach to see what made her qualified to be able to write a paper about the lava and its different types, while still having credible facts to back up the article. I couldn’t find much on her except that she works …show more content…
Lava wasn’t always called “lava” it wasn’t till 1737 after the Mount Vesuvius eruption that it got its name. Reason being that it got its name is because it oozes from the sides of the volcano which in Latin its root word means to fall or ooze. There is a difference between magma and its close brother lava. Magma is liquid rock that is still inside the earth and has yet to come out. Lava on the other hand is magma that is no longer inside the earth. The most common type of liquid rock outside the earth is the lava variation is called basalt. There are two words that describe Basalt and they both come from Hawaiian descent which both describe the cooling rate and thickness of the lavas. Pahoehoe is the slow-moving type of the lava and a’a is the other type but this type moves very quickly and very suddenly with no warning. There are also different types of lava besides the Basalt lava. Andesitic and Rhyolitic both have lots of gasses present in the lava and tend to erupt more violently. Underneath Yellowstone there is a super volcano and inside it there is Rhyolitic magma, luckily for us this volcano is ranged to blow it tops anywhere between 1 and 700,000 years. Another thing about lava is that it can be categorized by the chemicals that it’s
