Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
Rocks that contain crystals exhibit a coarse texture. The crystals within the rock are generally large enough to be seen with the naked eye, giving the rock a grainy appearance.
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
No, sugar crystals are not considered rocks. Rocks are naturally occurring solid objects made up of minerals, while sugar crystals are formed from a dissolved substance (sugar) that solidifies as it crystallizes.
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.
Yes. All intrusive igneours rocks and many extrusive rocks have crystals.

Not all of them. Volcanic glass does not have crystals.

All rocks have crystals, or at least crystalline structures. Sedimentary rocks may not have crystals as such, but the individual grains have internal crystal structures. All magmatic and metamorphic rocks have crystals, though they may be too small to be seen without the aid of a microscope. Only possible exception is Obsidian (volcanic glass) which may be amorphous.

You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.
There are LARGE CRYSTALS....
No. Intrusive igneous rocks have large crystals because they cool slowly.
