Why would the crystals in a intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?

Crystals tend to be large if they form slowly either from the melt or from solution. Intrusive igneous rocks are formed when magma forces its way between existing rocks and then gradually cools and sets. The surrounding rocks provide good insulation, so the magma cools very slowly, and big crystals, such as those in granite, are formed. Chemical sedimentation processes vary, but are usually more rapid than intrusive igneous cooling.

What solid is made up of crystals?
a crystaline solid
What rocks are copper isolated from?
copper is isolated from igneous rocks because it is a sedimentary
What type of rock is a crystal rock?
Virtually all rock contains mineral crystals of various sizes. Most volcanic rocks such as granite contain crystals of quartz and other minerals. Crystal size varies depending on the speed of cooling.
Where do chemical rocks form?
Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
What is extremely rapid cooling of lava in which no crystals form?
Extrusive is when Igneous rock is formed from magma below Earth's surface.
Why would the crystals in an intrusive igneous rock be larger than the crystals in an chemical sedimentary rock.?
Intrusive rocks form beneath the earth's surface, so they cool very slowly, which produces larger crystals.

What are crystals igneous sedimentary or metamorphic?
its igneous and sedimentary and metamorphic
Are large crystals intrusive or extrusive igneous rock?
Intrusive
How are geodes classified?
The igneous geodes are classified as intrusive and the sedimentary geodes are classified as chemical based on properties.
How can you determine if an igneous rock has had an intrusive or extrusive organ?
by the size of the crystals, big crystals intrusive, small crystals extrusive
Can a sedimentary rock be directly transformed into a igneous rock?
Yes, by heat and pressure. It could turn into two types of igneous rocks: intrusive and extrusive. An intrusive igneous rock is formed by heat from a volcano. It is cooled slowly, and has big crystals. An extrusive igneous rock is formed outside a volcano. It cools slowly and has small/ not visible crystals. So basically, if the sedimentary rock gets into a volcano, it can turn into an igneous rock. Hope that answered your question.
What is the type of Igneous rock that forms underground?
Igneous, Metamorphic, and Sedimentary rocks
What is a black intrusive rock with small crystals?
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
Is silica intrusive or extrusive?
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.
