Igneous Rock
Igneous rock is formed from cooled magma or lava. The magma turns solid as it cools, and eventually becomes rock. It is sometimes crystallized.

What is the name of the rock that is formed from molten rock that cools deep within the earth?
The general name is intrusive igneous rock. The specific name depends on the composition. The most well known example is granite, but other common types include diorite, syenite, and gabbro.
When metamorphic rock changes to magma the magma rises and cools to become?
A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock.
In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
What process happens for there to be an igneous rock?
For a rock to be classified as an igneous rock it must have been formed by a volcano. So, it could be made out of cooled magma or lava. The different types of igneous rocks are due to different cooling processes. It could have been spewed into the air and cooled on the way down, it could have been underwater and cooled immediately, or it could have oozed out of some crack and cooled slowly. Another way it may have solidified is by a decrease in pressure. For example, being spewed into the air and falling a couple hundred feet.
What is magma that hardens after being forced into a crack across rock?
Magma that hardens after being forced into a crack across rock is called a dike.
What are the most popular colors of granite sink?
Light coloured granite is actually one of the best choices for a busy kitchen. Alaska White is one of the most popular colours of granite in the market today. It is a frosty blend of pale silver and frosty whites, marketed with warm neutrals and onyx hues. It is a timeless & classic granite material that will never go out of style. Five Stones is considered a leading Exporter of Alaska White Granite in India. However, Alaska White granite slabs can vary in appearance considerably, with some slabs of this granite being much more attractive than others.
When molten rock undergoes crystallization above ground what type of rock results?
Extrusive igneous rock is the result of above ground crystallization.
Why don't stainless steel knives do not harm granite cutting boards?
Most of the cheaper stainless steel knives are made out of lower grade steel, softer than granite. They will dull quite quickly in that service.
True knife steel, the 440 series MAY scratch the granite, depending on the quality, which one of the 440's its made out of and how it was heat treated.
What benefits does quartz give to humans?
"Rock crystal is also known as clear quartz or quartz crystal. It is often called the "master healer" for its alleged ability to cleanse and purify the human body and stimulate the immune system. In effect, it is believed that rock crystal can restore balance to the physical, mental, emotional and spiritual planes. It can be worn as jewelry, or placed strategically on nightstands or coffee tables or other suitable locations to provide maximum benefits.
Is pumice used in handcleaner?
The brand of hand soap called "Lava" is alleged to contain pumice. Lava soap really does have pumice in it.
Why are igneous rocks impermeable?
Igneous rocks are typically impermeable because they form from the cooling and solidification of molten magma deep within the Earth's crust or on its surface. This rapid cooling process prevents the development of interconnected pore spaces that would allow fluids to flow through the rock. Additionally, the crystalline structure of igneous rocks tends to be tightly packed, further reducing permeability.
Is a sapphire an igneous rock?
Original Answer by ...? (with edit):Sapphire isn't a rock, it's a mineral.
who ever wrote this know that people asks "In which type of ROCK does the sapphire falls in " okay and yes it is not a rock and no its not an igneous rock its a metamorphic rock .
Edit (by Luke Tomaneng): I can understand the confusion, because sapphire can sometimes be found in igneous rocks (and, as the answer in italic states, some metamorphic rocks as well). Though it is not a "rock" of its own, I suppose sapphire can at times be considered to be part of an igneous rock.
How do you know when rocks crystallize?
when rocks crysallize their are differences. on of the main differences is that the crystals in the rock grow larger than they already are. secondly there size increase from their original size.
Is granite a type of cooled lava?
Granite is formed from molten rock that has cooled. Since it forms underground, however, the molten rock that it forms from is called magma rather than lava.
Igneous rock forms from the cooling of molten material called magma or lava.

Igneous rocks are not an acid. Volcanic activity can release gases that can form acid on contact with water, including sulfur dioxide and carbon dioxide which form sulfuric and carbonic acid respectively. Igneous rocks were once divided into classifications of "acidic" and "basic" based on the idea that differing properties were a result of differing amounts of silicic acid. This idea has been abandoned as we now know it is silica rather than silicic acid that plays a large role in the properties of igneous rock.
Sure. If you can find a fluid that's more dense than the rocks to float them in.
For example, mercury is almost 6 times as dense as granite, so a lump or slab of granite will ride right up there high in a pool of mercury.
==========================================
Pumice, it has air pockets in it. If the weight to water displacement is less any object will float.
answ3. Heavy liquids are used in mineral separation. A poly-bromine - ... etc liquid used to be used , but considerations of ozone layer, and toxicity have led to it being abandoned.
Sodium polytungstate, with a specific gravity of about 3 is now the recommended material. And, some rock minerals will float on it - hence its value.
What are Factors affecting the toughness of rock?
The factors affecting toughness of rock includes;
1. Rock Texture.
2. Rock Structure.
3. Weathering activities.
4. Metamorphism.
