What Crystallization from cooling magma describes one way that?
minerals form
What is granitic magma?
granitite magma is a course -grained igneous rock.
What is the difference between intrusion and extrusion igneous rocks?
Both are formed from the crystallization of minerals caused by the cooling of magma.Intrusive igneous rocks cooled below the surface of the planet, however, and generally display larger crystals due to the increased amount of time spent at mineral crystallization temperatures from the insulating effect of surrounding material.Examples: granite, gabbro, diorite, peridotite.Extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain.Examples: obsidian, rhyolite, pumice, scoria, basalt.
Is porphyritic rock extrusive or intrusive?
A porphyritic igneous rock is one with a texture containing large isolated crystals (phenocrysts) in a mass of fine grained crystals . Porphyritic texture indicates that a magma has gone through a two stage cooling process. The magma has cooled sufficiently underground to allow some minerals to crystallize and grow in size; the magma is then expelled above ground where the remaining liquid magma solidifies quickly, allowing only small crystals to develop.
Explain how igneous rocks form?
Igneous rocks are one of the 3 main type of rocks, the others being sedimentary and metamorphic rocks. Igneous rocks are formed from the cooling of lava and magma. There are over 700 kinds of igneous rocks, and most are found beneath the surface of the Earth's crust.

One of two conditions needed to melt minerals into magma?
crystallization above ground and crystallization below ground
What Rock formed by the crystallization of magma?
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
What is granitic magma?
granitite magma is a course -grained igneous rock.
Why is the magma moving under the lithosphere?
Magma moves under the lithosphere because the aesthenosphere (and magma) are ductile - they act as a fluid, although a very viscous one, and they do flow. The viscosity of a magma depends on its mineral composition. Magma will move in convection currents throughout the aesthenosphere due to the heating and cooling of it as it travels throughout the aesthenosphere.
What is an ignous rock?
Igneous is one of the three major rock classifications in geology. An igneous rock is a rock formed from the cooling and solidification of magma or lava.
What is molten rock that has not reached the surface?
It is called an igneous rock.Igneous rock is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
What are 5 things that come out of erupting volcanoes?
there are many parts of a volcano. There is the magma chamber: where all of the magma is held. There is the pipe: where the magma comes up and through the volcano. There is the dike, where where a slab forms when magma forces itself across rock layers. There is the crater, where a bowl shaped area forms around a volcanoes central vent. There is the vent: where magms comes out.

One of the unifying theories of geology which describes the surface of the Earth as massive slabs riding on the underlying magma of the mantle is called?
The theory of plate tectonics.
What rock does crystallization turn into?
All Igneous rocks are crystalline, but also note that Metamorphic rocks are also often crystalline, at least to a certain extent. Both of these categories always contain some crystals.
Why is magma a slushy mixture of crystals and molten rock?
Slush is a word given to describe half melting water ice where crystals of ice are present together with a little liquid water. If one had a magma made of crystals in present together with liquid rock - this could be described as a "slushy" mix BUT please note a normal Magma will be entirely liquid until it moves to environment where it begins to cool (at which point crystals will start to form in it) - magma is ONLY a slushy mix for a short time - just before it solidifies.
