Igneous form when molten rock cools and solidifies.
Granite is an intrusive igneous rock, meaning it forms when molten rock cools deep underground. There are also extrusive igneous rocks, which cool on the surface after erupting from a volcano.

What igneous rocks that form from magna cools slowly?
Intrusive igneous rocks, like granite.
Is it true that igneous rocks form only beneath earths surface?
It is not true. Extrusive rock forms on the surface from solidifying lava.
What are the economic benefits of igneous rocks?
economic benefits of using igneous rocks are...... igneous rock produces rocks like granite which is impermeable and is strong so good for resovoirs and kitchen work tops which would benefit the area of the place were they mine the granite. there are other rocks but that is proberly the main rock which helps the economic benefits.
Why do igneous rocks form?
Volcanic activity will produce igneous rock.
What happens to ingneous rocks when placed in a cold environment?
nothing an igneous rock is a rock like any other to test this put granite in the freezer.
What igneous rocks that form from magna cools slowly?
Intrusive igneous rocks, like granite.
What type of rocks form from melting and cooling?
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
How is granite like gabbro?
Both of these rocks are intrusive igneous rocks (solidified from molten material under the surface).
Is it true that igneous rocks form only beneath earths surface?
It is not true. Extrusive rock forms on the surface from solidifying lava.
Granite pumica and scoria are igneous rocks Why doesnt granite air have airholes like the other two?
it is because granite is formed by magma that cools under the earth unlike pumica and scoria that form while a volcano erupts.

Which rocks are extrusive igneous rocks where do they form?
Extrusive igneous rocks are formed when magma reaches the Earth's surface and cools. Since this magma is exposed to air and/or water, it cools very quickly, creating finer-grained, sometimes glassy rocks. Obsidian and pumice are both extrusive igneous rocks. Conversely, intrusive igneous rocks, like granite, are created when magma cools in the Earth's crust, which is a slower process.
How are igeneous rock formed?
Igneous rocks are formed by heat, pressure and cooling. They can be formed inside a volcano or outside a volcano. If they are formed outside the volcano the rocks are called extrusive igneous rocks, like basalt. If it is formed inside the volcano the rocks are called intrusive igneous rocks, like granite.
What type of rock are mostly found in mountains?
volcanic mountains are mostly associated with igneous rocks and sedimentary rocks at their slopes can be found due to weathering,but mountains such as fold mountains can contain igneous rocks,metarmophic ro cks and even sedimentary rocks at their slopes
Name the three families of igneous rocks?
This is a very simplistic answer. But, it should reveal the basic processes involved in rock formation.1. Sedimentary, like coal and limestone. They are made from particles of substances that settle and coalesce into a layer that becomes rock.2. Igneous, like granite and basalt. These rocks were formed by heat. Think of lava.3. Metamorphic: Marble and slate. These are rocks that were in another form and got changed by pressure into their present form.
What is a type of rock formed by cooled magma?
Igneous rock is formed from the solidification of magma as it cools.
What igneous rock cools and hardens under surface of crust?
Many types of rock form like this; any igneous rocks with large crystals, such as granite and gabbro (the phaneritic (large-crystaled) version of basalt) would be the most common.
