Magma is under a lot more pressure which influences its composition and behavior. Magma moves underground in response to stress fi.

Magma can remain in a chamber until it cools and crystallizes forming igneous rock, it erupts as a volcano, or moves into another magma chamber.There are two known processes by which magma changes: by crystallization within the crust or mantle to form a pluton, or by volcanic eruption to become lava. Magma, teor em sílica, temperatura e erupções 1. O magma é uma mistura complexa de silicatos, que se encontra em fusãoa temperaturas que variam, mais ou menos, entre os 800º C e 1200º C.Consoante o teor em sílica, os magmas podem dividir-se em:1 ácidos, quando apresentam mais de 60% do teor em sílica,2 andesíticos.

28/08/2017 · Magma becomes lava when it comes out on the surface of the Earth through a volcanic vent. Once magma gets to the Earth's surface and erupts from a volcano, it is officially known as lava. Volcanoes are ranked as one of the most powerful natural phenomena observed on. First, I think you meant to write puss, not plasma, and it’s smegma, not magma. Puss is the white junk that that erupts out of a pimple that may look the size of a small volcano when it is squeezed between a subduction zone and the continental l. Jejím podzemním ekvivalentem je magma, které vystupuje sopečným jícnem nebo v okolí litosférických zlomů a prasklin na zemský povrch, kde se následně rozlévá do okolí v závislosti na své viskozitě. Teplota lávy se pohybuje obyčejně v rozmezí mezi 750 a až 1 200 °C.

You've asked a good question. The terms are really are referring to the same stuff molten rock. It is just easier this way. If someone is talking about magma you know they are talking about when it is still underground but if they are talking about lava you know they are talking about after it has erupted. When the magma reaches the surface, it is called lava. The rate at which the magma cools determines the kind of igneous rocks that are formed. Faster cooling surface lava creates rock that is fine grained or aphanitic. The rapid cooling doesn't allow large crystals to form. 22/10/2007 · Magma auctually isant the hottest Magma reaches close to 2300 F. While Lava is the same tempreture but you have to take into consideration lava is magma but lava is when it touches the ground in and it reaches surface and when in erupts valcano go boom boom. lava rapidly cools to surface tempreture it can take a few days if it.

Classification of rocks, minerals, and magma based on the silica content present in them defines them as either mafic or felsic. Learn more about the Mafic vs. Felsic geological classification through this ScienceStruck article. 24/09/2012 · Let's settle this, the difference between magma and lava is as follows. Lava was magma that forced its way to the surface via volcano or plate shift and solidifies into molten rock. While magma stays a "liquid" in pockets underground, waiting to be forced up by a shift in tectonic plates.

Acid lava comes from composite cone volcanoes, is slow moving and viscous. Basic lava comes from shield volcanoes, is runny and flows faster. Acidic lava is felsic, or high in quartz and potassium feldspars. Basic lava is mafic, and higher in plagioclase feldspar.
