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 type of rock is formed by cool lava or magma?
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
What is a texture where you cannot see the individual minerals in igneous rocks?
It depends on what texture pack your using i recomend lookoing on Minecraft.net
When lava reaches the ocean does it become a rock?
Yes, the heat of the lava may well turn some of the water into steam, but the sea will cool & solidify the lava.
Do igneous rocks have smaller crystals than those formed above the surface?
Igneous rocks formed within the earth crust have larger crystals than those formed on the surface because they have little or no interaction with atmospheric conditions and they cool very slowly.
What word starting with P means the rock can absorb water?
Porous means a rock is able to absorb water.
What igneous rocks does marble turn into?
It's impossible to say what specific igneous rock the rock marble may become after it is melted and becomes mixed with other molten rock before solidification into an igneous rock. It would most certainly have none of the characteristics of the original marble.
Rock made from erosion into small particles, and compacted under great weights of materials above are called, "Sedimentary rocks".
What is Ultrabasic Igneous Rock?
Ultrabasic is a general term, probably first used by J.W. Judd in 1881, applied to igneous rocks containing little or no feldspar and characterized essentially by the abundance of one or more common mafic minerals such as olivine, pyroxene, and amphibole. Chemically, the rocks contain <45% SiO2 and the term ultrabasic is used along with basic, intermediate, and acid (ic) in a chemical classification of igneous rocks as distinct from ultramafic, mafic, and felsic which refer to a mineralogical color index. However, the term ultrabasic commonly is used incorrectly as synonymous with ultramafic to include such rocks as ultramafic pyroxenites that contain as much as 55% SiO2.
Why are dark igneous rocks heaver then light igneous rocks?
Dark igneous rocks usually have higher amounts of heavier elements such as iron. Light-colored igneous rocks tend to be richer in lighter elements like sodium and aluminum.
What can transform igneous rock into sedimentary rock?
Igneous rock can become sedimentary if it is weathered into sediment and then lithified.
Sorry i said you at the end instead of me):
What processes found at hot spots will help igneous rock form?
Igneous rocks are formed around hot spots when there is an increase in temperature, a decrease in pressure, or a change in composition. Igneous rock is formed through the cooling and solidification of magma or lava.
How do geologists classify igneous rock?
Geologists classify igneous rocks based on their mineral composition, texture (grain size and arrangement of crystals), and overall chemical composition. Igneous rocks are further categorized as intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface) based on where they solidified.
Is rhyolite formed at convergent plate boundaries?
Rhyolite can form at convergent plate boundaries where magma is generated from the melting of continental crust material being subducted. Subduction zones can provide the necessary conditions for the production of rhyolitic magma, resulting in the formation of rhyolite.
Why does volcanic rock magnetize?
Volcanic rock, especially basalt, contains some iron. When the rock is still molten the particles of iron are free to move, but are influenced by Earth's magnetic field. When the lava hardens into rock these iron particles are locked in place, essentially recording the orientation of Earth's magnetic field.
Yes
What names is given to the molten rock below the earths surface?
Magma. Magma rises towards the surface when it's less dense than rock around it. Otherwise, it collects in magma chambers and cools, forming igneous rock.
