igneous rock
Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.
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.
No. Igneous rock forms from the cooling of magma.
When magma cools down it forms a type of rock called igneous rock. Igneous rock can cool inside the earth or it can cool after it has come out on the earth's surface. When it is formed inside it is called intrusive but when it is on the earth's surface it is called extrusive.

Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.

When magma cools slowly, it forms igneous rocks such as granite or diorite, which have large mineral crystals because they had time to grow as the magma solidified.
feldspar
extrustive igneous rock... it forms on the outside of a volcano and has small or no crystals at all.
Magma forms from heated rock--it cools--minerals form--when totally solidified it is a rock.
