Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What three factors affect the formation of magma?
1. the coarse grained rock 2. slow cooling magma 3. fine grained rock
What are the three basic ways that minerals form 1 solidification of a melt 2 precipitation from solution and 3 solid state diffusion?
Yes, all three.
What is an underground molten mixture of rock-forming substances gases and water from the mantle?
Mantle rock, usually fed by subducting crusts at destructive plate boundaries, melt under the heat, creating magma (or igneous melt). This magma is usually less dense than the surrounding (country) rock and so rises to or near the surface, forming igneous rocks in two ways: 1) The rock does not reach the surface, but cools and crystallises inside the Earth, creating INTRUSIVE igneous rocks. These usually have large crystals as they cool more slowly due to the hot surrounding temperatures. 2) The rock reaches the surface via volcanic or fissure eruptions as lava, and cools and crystallises very quickly on the earth's surface forming EXTRUSIVE igneous rocks. These have fine crystals due to the quick cooling time and colder surrounding temperatures.
What is an example of porphyritic texture?
There are 2 or more very distinct grain sizes. The smaller grains are called phenocrysts and the material around it is called matrix or groundmass. The phenocrysts are 0.3 - 5 mm. To truly see what a porphyritic texture looks like just search on google images and you'll see a nice example along with a diagram that explains it.
Magma cooling in 2 stages slow and then fast what is the resulting texture?
The resultant rock would have a porphyritic texture; large crystals (usually feldspars) scattered among small crystal grains.

How are the 2 types of igneous rock made?
They are either made through the fast cooling of lava, or the slow cooling if magma in the Earth.

How tall is Mia Magma?
Mia Magma is 5' 2".
What would happen if water was present in wet magma?
wet magma is nothing but magma which is cooling down.if wet magma touches water, it will cool down the magma.2. Much volcanic material, magma included contains water - hence forming clouds above an active volcano. But seldom is material ejected from the throat steaming when it lands, therefore most of the moisture is rapidly dissipated.Volcanic glasses can occasionally contain water, under large pressure and temperature, and upon the explosive ejection, may form pumice or ignimbrite.Presumably the water in the magma was entrained during the subduction phase of the cycle.
What are 2 kinds of texture used in art?
Two kinds of texture in art are real or actual texture and simulated or representational texture.
What are the life stages of a guppies?
2 stages
What determines how large the crystals and an igneous rock Will be?
The speed at which the magma/lava cools ie. fast cooling = not much time for crystals to form = little or no small crystals slow cooling = much time for crystals to form = big crystals
How do porphyritic rocks form?
I believe that porphyritic andesite is formed from volcanic ash and bits and pieces of minerals that eventually become ejected from the volcano. How the andesite becomes porphyritic is that it formed inside the volcano before being blown out of along with the magma and hot gases. You can find silver and gold specs as well as a few other metals encased by a smooth texture of solidifyed ash. Lee Durst (WVC 08)
