was used extensively by ancient civilizations for vases and other decorative artwork and is still used for art today (Figure 1). Granite (figure 2) is used both in building construction and for statues.
What are three common uses of igneous rocks?
People use granite for countertops, buildings, monuments and statues. Pumice is also an igneous rock. Perhaps you have used a pumice stone to smooth your skin. Pumice stones are put into giant washing machines with new jeans and tumbled around.
What are two common uses of igneous rocks quizlet?
What are two common uses of igneous rocks? Igneous rocks are used for building and cleaning or polishing.
What makes igneous rocks useful construction materials?
Igneous rocks are often used as setts in areas of heavy wear, because they withstand both weathering and erosion better than most sedimentary rocks, or even concrete. Igneous rocks are often used as a plinth at the base of an office front – for the same reason.
What are examples of igneous rocks?
There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below the Earth’s surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above the Earth’s surface.
What is special about igneous rocks?
The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don’t have much time to grow, so these rocks have a very fine-grained or even glassy texture.

What makes igneous rocks important quizlet?
Igneous rock is so strong because it has interlocking grain textureand many minerals within this type of rock are resistant to weathering.
What are some uses of igneous rocks in the construction industry?
which qualities of igneous rocks have long made them useful for tool and building material? granite is used for building bridges and buildings, basalt is used in gravel roads and pumice is used for abrasives such as pumice stones to remove calasus on our feet.
What are the two types of igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
What are the 5 examples of igneous rocks?
These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.
How do we use igneous rocks in everyday life?
Pumice is used in toothpaste and cosmetic products, while basalt is used in the construction of statues and buildings. Intrusive igneous rocks form when magma hardens below the earth’s surface. Granite is an example. Granite is used in countertops, statues and tombstones because of its durability.
How do you describe igneous rocks?
Igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material. Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material.
What is another name for igneous rocks?
Igneous rocks are also known as magmatic rocks. Igneous rocks are divided into two types: plutonic and volcanic rock.
What are the 3 main types of igneous rocks?
When molten rock, or melted rock, solidifies, igneous rocks are formed. There are two types of igneous rocks: intrusive and extrusive.Extrusive Igneous Rocks andesite. basalt. dacite. obsidian. pumice.
What are 5 facts about igneous rocks?
Quick Facts: – About 95% part of earth’s crust is made up of igneous rock. Even earth’s moon is made up of igneous rock. The lightest rock on the earth, Pumice rock is also an igneous rock. Igneous rocks are helpful in the growth of plants because they contain many minerals which can help a plant to grow.
What are 3 facts about igneous rocks?
Igneous rocks are up! Igneous rocks are formed in molten magma. There are two types of igneous rock. Igneous rock is also formed when magma cools and crystallises into a rock formation. Most of the earth’s crust is made out of igneous rock. Many mountains are made out of igneous rocks.
What is the important of rock?
Rocks have a broad range of uses that makes them significantly important to human life. For instance, rocks are used in construction, for manufacturing substances and making medicine and for the production of gas. Rocks are also extremely vital to scientists as they provide clues about the Earth’s history.
What is the most common igneous rock?
Granite: the most common igneous plutonic rock. Contains essential quartz, plagioclase and alkali feldspar, usually with hornblende and/or biotite and/or muscovite. Granodiorite: a plutonic rock with essential quartz and plagioclase, with lesser amounts of alkali feldspar and small amounts of hornblende and biotite.
What are the 4 types of igneous rocks?
Classification By Mineral Abundance Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic.
What is the major difference between felsic and mafic igneous rocks?
In a widely accepted silica-content classification scheme, rocks with more than 65 percent silica are called felsic; those with between 55 and 65 percent silica are intermediate; those with between 45 and 55 percent silica are mafic; and those with less than 45 percent are ultramafic.
What is the difference between the composition of felsic and mafic igneous rocks?
The difference between Mafic and Felsic rocks are the silica content present. Since igneous rocks are characterised by silica content in them, mafic is the one with less silica content (approx. 45-55%) while felsic is the one with a greater silica content (approx. 70-90%).
What are igneous rocks quizlet?
igneous rock. A type of rock that forms when magma or lava COOLS and SOLIDIFIES. melting and solidification.
What is the economic importance of igneous rocks?
Economic Uses Many types of igneous rocks are used as building stone, facing stone, and decorative material, such as that used for tabletops, cutting boards, and carved figures.
