How quick does extrusive igneous rocks cool?
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
What type of crystal gain that forms when molten rocks cool slowly?
Intrusive
What type of crystal grain forms when molten rocks cool slowly?
Quartz
Why would the crystals in an intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?
Think about this: When molten rock cools slowly, bigger crystals are created.Then think about this: Intrusive rocks cool quite slowly because they are created in the earth's crust.So... Intrusive igneous rocks have bigger crystals. Molten magma in the earth's crust cools slowly making rocks like granite with big crystals.Get it? got it?GOOD!!
Do intrusive rocks cool quickly?
No. Usually very slowly.

No. Intrusive igneous rocks have large crystals because they cool slowly.
What type of crystal gain that forms when molten rocks cool slowly?
Intrusive
Why do igneous rocks that cool from magma underground cool so slowly?
They are surrounded by hot rock and are insulated by the surrounding material. Rocks are poor conductors of heat.
Which kind of igneous rocks form when magma cool slowly?
intrusive igneous rock
What type of crystal grain forms when molten rocks cool slowly?
Quartz
Do metamorphic rocks cool slowly?
Most do, however some do not, for instance a pseudotachylyte cools quickly.
Did these rocks cool relatively fast or slowly?
Since you have neglected to describe them or provide pictures, that cannot be determined.
Why does basalt rocks cool slowly?
Basalt cools off quickly because it is formed under water.

Why would you expect the crystals in an intrusive rock to be larger than the crystals in an extrusive rock?
Because intrusive rocks cool more slowly which makes the rocks larger.
