the length of time the magma had to cool
Factors that can affect the texture of an igneous rock include the rate of cooling (fast cooling results in fine-grained texture and slow cooling results in coarse-grained texture), the mineral composition of the rock, and the amount of gas trapped within the magma during solidification. Other factors can include the amount of pressure present during crystallization and any subsequent deformation or alteration processes.
Factors that can affect the texture of an igneous rock include the rate of cooling, mineral composition, and the amount of gas bubbles present during solidification. A slower cooling rate typically results in larger crystals, while a rapid cooling rate usually produces finer-grained rocks. Higher gas content can lead to the formation of vesicles or pores in 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.

The size of the mineral crystals in an igneous rock determines the rock's texture.

The type of igneous rock that forms is primarily determined by the chemical composition of the magma from which it solidifies. Factors such as pressure and temperature can influence crystal size and texture, but they do not affect the type of igneous rock that ultimately forms.

Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
