Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.

Do igneous rocks have small crystals large crystals or no crystals?

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.


Do igneous rocks have large crystals?

It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.


What are Igneous rocks that have large crystals and small crystals?

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.


Does melted rock that cools quickly result in igneous rock with large mineral crystals?

No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.


Are large crystals intrusive or extrusive igneous rock?

Large crystals are typically characteristic of intrusive igneous rocks, which form beneath the Earth's surface from slow cooling of magma. Extrusive igneous rocks cool quickly at or near the Earth's surface, resulting in smaller crystals or glassy textures.

Igneous rocks with large crystals?

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.


How can you tell if a intrusive rock forms?

Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.

What Igneous rocks have large crystals and form when melted rock cools slowly and hardens underneath earth's surface?

They are called intrusive igneous rocks.


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.


If the lava cools quickly the crystal are what?

If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.


What is an igneous rock with small crystals?

If you're not looking for anything specific, any extrusive igneous rock will have smaller crystals, if any at all. This is because they cool quickly on the surface, leaving little time for crystals to form/grow.


Why is it that some igneous rock is made of large crystals and some is made of small crystals?

An igneous rock's crystal size is dependent on how long it takes to cool from magma into a solid. Intrusive igneous rocks, the ones that solidify from magma underground, are slow to harden, giving crystals plenty of time to grow larger. Extrusive igneous rocks, formed from lava above ground, cool fairly rapidly, not allowing the crystals much time to grow in size.
