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.
What conditions lead to formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
What is an extrusive igneous rock with large crystals?
granite
How can you tell that a rock is a igneous rock?
Well The Igneous Rock: When it Forms Underground the Pressure combines with Large crystals :)
What is an example of an intrusive igneous rock with large crystals?
Porphyrite of any composition, granite, gabbro, diorite. Most intrusive igneous rocks have crystals large enough to see with the naked eye. Another term used to define an igneous rock with large crystals is coarse-grained.
A type of instrusive igneous rock with large crystals?
Gabbro.
What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
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.
What is the texture called when an igneous rock with large crystals scattered on a background of much smaller crystals?
The texture is called porphyritic. It forms when an igneous rock cools at different rates, resulting in large crystals (phenocrysts) surrounded by a matrix of smaller crystals (groundmass).
What is a seven letter word for an igneous rock with large crystals?
granite
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.
When a igneous rock with large cystals cools what is it?
An intrusive igneous rock has larger crystals than an extrusive igneous rock because it has had a longer period of time to solidify underground.
