How can you tell if a intrusive rock forms?
Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.
How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
A foliated metamorphic rock forms when crystals .?
A foliated metamorphic rock forms when crystals combine and form visible bands
What kind of rock forms when magma intrudes into other rocks?
Intrusive igneous rocks. These have large crystals because it is warmer underground, therefore it has more time to cool, therefore the crystals have more time to form and grow, thus large crystals.
How can you tell if a intrusive rock forms?

Where did an igneous rock form if the rock contains large crystals?
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
What type of crystals form when magma cools very slowly deep beneath the Earth's surface?
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
Large crystals with well-formed crystal faces tend to form when?
Large mineral crystals can form when magma is able to cool slowly underground, creating intrusive igneous rock.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
A foliated metamorphic rock forms when crystals .?
A foliated metamorphic rock forms when crystals combine and form visible bands
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
What is a glassy rock that forms when crystals do not get to form?
feldspar
What affects the size of crystals formed from magma?
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
What rocks form from cooled magma below the earth sucfaceand has small crstal?
extrustive igneous rock... it forms on the outside of a volcano and has small or no crystals at all.
In what order does magma become a rock?
Magma forms from heated rock--it cools--minerals form--when totally solidified it is a rock.
