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 determines how large the crystals in an igneous rock will be?
The cooling rate of magma determines the size of crystals in an igneous rock. Slow cooling allows larger crystals to form, while rapid cooling results in smaller crystals or a glassy texture. Other factors such as mineral composition and amount of available space for crystal growth also influence crystal size.
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 determines how large the crystals in the igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
What size of rock texture refers to igneous rock?
The size of the mineral crystals in an igneous rock determines the rock's texture.
What igneous rock does not have large crystals?
sedimantry
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 factor determines if an igneous rock has no crystals small crystals or large crystals?
The rate at which the magma cools determines the size of crystals in an igneous rock. Slow cooling allows for large crystals to form, while rapid cooling results in small or no crystals. Other factors such as mineral composition and pressure can also influence crystal size.
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 :)

A type of instrusive igneous rock with large crystals?
Gabbro.
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.
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).
