What is the relationship between an igneous rock's texture and where it was formed?
Answer (3)
where it is formed is probably the reason why it has that certain texture. There could of been a global situation in that place where it was formed.
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.
The texture of igneous rocks reflects their formation process: intrusive rocks form slowly underground and have a coarse-grained texture, while extrusive rocks cool quickly at the surface and have a fine-grained texture. This cooling rate determines the size of the crystals within the rocks. Examples include granite (intrusive) with visible crystals and basalt (extrusive) with small crystals.
