It is mineral
Large crystals with a coarse crystal grain texture.
crystal
The texture of the rock product of slow cooling magma is referred to as coarse grained.
its false
Fine crystal grain.
True. Larger crystals form when molten rock cools slowly because the slower cooling process allows atoms to arrange themselves into a more organized and larger crystal structure. In contrast, rapid cooling leads to smaller crystals or even amorphous forms like glass, as there is insufficient time for the atoms to bond into larger structures.
fine
Fine
Small crystal grains form when molten rock cools quickly. In an extrusive igneous rock, it's referred to as aphanitic texture.
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
Quartz
When molten rock cools quickly, fine-grained crystals form. This happens because there is not enough time for larger crystals to grow before the rock solidifies, resulting in smaller crystals being formed.
