What kind of igneous rock texture results from slow cooling magma?
Wiki User

A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture.
The slower the magma cools the more time minerals have to crystallize and thus grow bigger.

∙ 9y agoSince the cooling process is very fast extrusive igneous rocks have very small crystals (fine grained). On the other hand an Intrusive igneous rock cools very slowly beneath the surface and is created by magma. Since the cooling process is very slow intrusive igneous rocks have very large crystals (coarse grained).

The cooling and hardening of magma deep underground results in what?
The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.
Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
Which type of rock forms from magma?
magma is a mixture of several different types of rock.
Name the three major groups of rocks and describe how each forms?
The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
The cooling and hardening of magma deep underground results in what?
The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.
What factors can affect the texture of an igneous rock?
The length of time the magma had to cool
What does magma have to do with igneous rocks?
Igneous rocks are formed by cooling magma.
Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
How does the rate of cooling affect the type of igneous rock formed?
The rate at which the rock cool from the liquid magma determines their texture
What determine the texture of igneous Rock?
The texture is mostly determined by the time spent in cooling from magma or lava. The quicker the transition from molten to solid, the finer the texture.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
What causes igneous rock to form?
Igneous rock is formed from the cooling and solidification of magma or lava.
An intrusive igneous rock will have what type of texture?
Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
