What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
What are 3 ways igneous rocks are used and which one?
Igneous rocks are used as building materials for construction (e.g. granite countertops), crushed stone for roads and landscaping, and as a source of minerals for industrial purposes such as in the production of ceramics.
Which property most useful for identify igneous rocks?
The most useful property for identifying igneous rocks is their mineral composition, particularly the presence and proportions of key minerals such as quartz, feldspar, and mica. Additionally, texture, which includes grain size and the relationship between crystals, can provide significant insights; for instance, a coarse-grained texture indicates slow cooling, typical of intrusive igneous rocks, while a fine-grained texture suggests rapid cooling, characteristic of extrusive igneous rocks. These features combined help distinguish different types of igneous rocks effectively.
What characteristics make igneous rocks useful?
Igneous rocks are useful because they provide information about Earth's history, such as how they were formed and the conditions of their formation. They also contain valuable resources like metals and minerals. Additionally, igneous rocks are used in construction materials and as decorative stones.

Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Why are igneous are called primary rocks?
Igneous rocks
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
How do fine- grained igneous rocks from?
extrusive igneous rocks =/
What kind of igneous rocks for on earths surface?
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
Are granite rocks igneous rocks?
Yes. More exactly, intrusive igneous rocks.
