∙ 10y agoWhen molten rocks cool slowly they form "Large crystals" and they are expressed as "Coarse Grained" rocks. This is because the crystals had enough time to form and develop perhaps due to little or no exposure to atmospheric conditions that would make the molten rock cool fast.

What is a type of crystal grain that forms when rock cools Slowly?
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
