The texture is determined by the rate it takes the molten to cool to form the rock.
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.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
Obsidian is an igneous rock that has a smooth glass-like texture. It is formed when lava cools rapidly without crystal formation, resulting in a glassy texture.
When magma crystallizes, it becomes igneous rock. Igneous rocks are formed by the cooling and solidification of molten rock material. The texture and composition of the igneous rock are determined by the rate of cooling and the mineral content of the magma.
A term that describes an igneous rock texture with crystals that are present but not visible would be aphanitic. This texture indicates that the individual mineral grains are too small to be distinguished with the naked eye.
The length of time the magma had to cool
The size of the mineral crystals in an igneous rock determines the rock's texture.
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
fined grain texture
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
The effect of weathering is to reduce the volume of the igneous rock.
coarse texture
the rate the melted rock cools

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.
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
