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.

∙ 11y agoTime taken for the cooling process determines the texture of igneous rocks when they form. They may be intrusive or extrusive rocks. If the duration of the cooling process is longer the rock will be smooth, if it is shorter the rock will be rough.

texture
What is the texture of an igneous rock from magma that cools in two stages?
It's texture is porphyritic
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 characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
What could be determined if you knew the texture of an igneous rock?
You could determine whether the rock cooled underground or above the surface.

What is the texture of igneous rock?
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
What texture does and extrusive igneous rock have?
fined grain texture
What is the texture of the rock andesite?
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
What kind of texture does igneous rock have when it cools rapidly?
coarse texture
What are the factors that controls most texture in igneous rocks?
magma or lava controls most texture in igneous rock
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.
What determines the texture of an igneous rock'?
the rate the melted rock cools
What is The crystal size of an igneous rock is described as?
texture
