What Are Two Common Uses Of Igneous Rocks?
Igneous rocks have a wide variety of uses. One important use is as stone for buildings and statues.

Igneous rocks form when magma or lava cools and solidifies. Sedimentary rocks form when sedi- ments become compacted and cemented. Metamorphic rocks form when existing rocks are changed by heat pressure or solutions.
Why do extrusive igneous rocks usually have smaller crystals than intrusive igneous rocks?
Why are igneous rocks good for building?
Let us understand why igneous rocks make for good construction material. The rock is crystalline in nature with a structure that ranges from fine to coarse grained. This gives the structure very durable. Hence igneous rocks are a top preference for masons who construct houses.
Which two features of igneous rocks are determined by their cooling rate?
Igneous rocks are classified according to their texture and mineral or chemical content. The texture of the rock is determined by the rate of cooling. The slower the rock cools the larger the crystals form.
