it also includes the process that gives rise to magma and causes its movements in the earth. = It also covers expulsion of gases, lava, and solid materials from the opening in the crust. VOLCANO =Is a vent, hill, or mountain from which molten or hot rock and gaseous materials are ejected =In our country we have more than 200 volcanoes they are distributed in five volcanic belt intimately related to subduction or convergent process MAGMA =The term magma comes from the Greek word

material which is usually erupted from the Earth’s surface as lava, or magma at shallow depths or deep depths. Magma is a mush like material that can carry a load of minerals, but people often think of lava and magma as a liquid like material of molten metals. The three types of igneous rocks are extrusive, intrusive and platonic rocks. Extrusive rocks are rocks that form and cool on the crust of the Earth whether it is on the continental crust or the oceanic crust. Extrusive rocks cool quickly, within

core. The crust, the part we inhabit, is just a tiny fraction of the Earths mass. Most of the mass of the Earth is in the mantle, a majority of the rest is in the core (Nine Planets, 1994-2010). Earth has three layers of density: The core primarily metals, such as nickel and iron, resides in the central core and is the highest-density material. The Mantel forms the thick mantle that surrounds the core is mostly minerals that contain silicone, oxygen, and other elements and is a rocky material of modest

Mainya, the Fiendish spirit for control over the world. During this war between good and evil, Ahura Mazda and his assistants would defeat the evil Angra Mainya. Furthermore, all evil would be eliminated on earth in an ordeal in which fire and molten metal would burn away all evil and only leave behind good. It is believed that Zoroastrianism first appeared as a religion during the reign of Darius I in Persia. Zoroaster, as he was know by the Greeks, proposed this religion to Darius I and it

Layers of the Earth The planet earth was formed about 4.5 billion years ago, after the collapse of the super massive gaseous body. As time moved on, the earth cooled down and is still cooling, as of today. As a result of the cooling process, denser materials like iron and sulfur sank to the inside of the earth; whereas, lighter materials like silicates and water floated near the earth's surface. Coming to the topic of our discussion, our planet earth comprises several layers. Starting from

naming Earth’s layers. Layers of the Earth [pic] • Write a 150-word summary or list that describes the basic attributes of the layers you listed in the diagram. The inner core is made of solid metal, mostly iron-nickel alloy. The outer core is made of the same substance, just molten. The outer core is about the same temperature as the surface of the sun, while the inner core is cooler, thus making it solid. Scientists have confirmed this by examining waves and how they pass through the
