How Magma is Formed

There are three ways in which magma can be formed; through heat transfer, decompression melting and flux melting.

1. Heat transfer is the process in which a rising column of magma sends heat from it to the surrounding rock around it, causing it to be pushed beyond melting point and creating rhyolitic magma. 

2. Decompression melting, occurs when two separate tectonic plates begin to or have already separated, which causes the mantle below it to rise up between them. Once pressure begins to drop, the raised-up mantle begins to melt into magma.

3. Flux melting will occur when volatile matter, such as sulfur gases and water, is stirred into the body of the rock. This process typically precludes the creation of volcanic arcs and magma.

Fly Geyser, United States

Fly Geyser, located in the Nevada Desert of the United States, is a collection of three large, colorful mounds which frequently shoot five feet of water straight up into the air. It was accidentally created during the 1916s, specifically during a routine well-drilling. It worked normally until the 1960s, in which superheated geothermal water began to spurt out through the well. Dissolved minerals began to accumulate and gradually built up into the large, colored mounds we see and recognize today. Fly Geyser is amongst one of the most secluded places on Earth, as it is located on private property and no tourists or sightseers are allowed in.

Greetings, and welcome to my first Blog (or at least, my first blog pertaining to school). I am Alex Galbo, your average student who goes to CCHS and fends himself from the stresses of school work. I enjoy reading fictional books and drawing, in which I dream of someday becoming a writer, or a graphic novelist, or maybe even both!

I've decided to partake in Geology because I am very interested in learning more about the planet we live on, as well as the universe our planet and solar system exist in. I would be very interested to learn about the origins of many or the world's most interesting geological areas, such as the Reed Flute Cave, the White Desert, and the The Devils Tower. Out of these places, one particular place I would be very interested to see is Fingal’s Cave in Scotland; a sea cave on the uninhabited island of Staffa. The cave was formed entirely from hexagonally jointed basalt columns within a Paleocene lava flow, similar in structure to the Giant's Causeway in Northern Ireland.
