What else can I help you with?
What does porphyrytic texture indicate about the story of an igneous rock?
it tells you that the igneous rock formed in two stages,stage one occurred deep into the earth were large crystals formed from and then it eruptedas a volcano in stage two were small crystals formed
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
What are two types of igneous rock?
Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.
Rock formed from cooling inside the earth produces large crystals?
Yes, because slow cooling facilitates the growth of large crystals.
A type of instrusive igneous rock with large crystals?
Gabbro.
What igneous rock is formed in the earth?
Igneous rock formed in the earths crust is known as intrusive rock. The magma that forms it cools slowly and therefore, creates rock with large crystals. An example of an intrusive igneous rock is granite.

Igneous--formed inside the Earth?
Intrusive Igneous rock. They are formed voer a long period of itme inside magma chamber creating 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 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 is an extrusive igneous rock with large crystals?
granite
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
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 :)
