Because the surrounding materials are nearly the same temperature as the molten rock material.

What type of crystal grain forms when molten rocks cool slowly?
Quartz
What type of crystal gain that forms when molten rocks cool slowly?
Intrusive
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!!
Does magma cool above ground or beneath?
No. Molten rock under the surface is called magma. Molten rock above the surface is referred to as lava.
Why do igneous rock that solidify underground cools so slowly?
They are insulated by the surrounding rock and are in close proximity or part of a hot, molten, or partially molten igneous intrusion.
What type of crystal grain forms when molten rocks cool slowly?
Quartz
When molten rocks cool it becomes what kind of rock?

What is a type of crystal grain which is formed when molten rock cools slowly?
It is mineral
What type of crystals grain that forms when molten rock cools slowly?
Quartz
Did the diorite rock cool quickly or did it cool slowly?
yes
The size of the mineral crystals found in an igneous rock is directly related to the?
the rate melted rock cools.
Does magma cool above ground or beneath?
No. Molten rock under the surface is called magma. Molten rock above the surface is referred to as lava.
What determines the texture of a rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
