What are two extrusive igneous rock that contain crystals?
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Do igneous rocks that form inside the Earth's crust look different from the igneous rocks that form on the Earth's surface?
Yes. Igneous rock that forms on the surface will have small mineral crystals, or in some cases no mineral crystals. Igneous rock that forms below the surface will have larger mineral crystals, from the additional cooling time afforded by the insulating effects of the surrounding Earth material.

Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.

No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.

Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
Does gabbro have crystals?
Yes. Gabbro is an intrusive igneous rock with visible mineral crystals.
What is a mineral with crystals inside?
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks

The texture of an igneous rock depends on the size and the shape of its what?
mineral crystals
What is Granite crystal?
Granite is an igneous rock with visible mineral crystals.
Some WHAT igneous rocks have individual mineral crystals that are too small to be seen without magnification?
Some extrusive igneous rocks have individual mineral crystals that are too small to be seen without magnification.
