The texture of a rock consists of it's grain or mineral crystal size, the arrangement of the grains or crystals, and the degree of uniformity of the grains or crystals. Examples of rock texture would be: * Coarse grained--visible crystals or grains as in granite.
* Fine grained--small grains, invisible to the unaided eye as in shale. * Porphyritic--large visible crystals in a fine grained matrix as in granite porphyry. * Schistose--layers of flattened micaceous minerals such as in mica schist. * Foliated--a metamorphic rock texture of parallel mineral banding as in gneiss. * Homogenous--same grain apperance in all directions as in basalt.

What 2 properties classify rocks?
They use the mineral composition, color, and texture.
How are rocks idenified?
rocks are idenified by texture
What is the texture of igneous rock?
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
Metamorphic rocks are rocks that?
Usually have a rougher texture
When igneous rocks solidify what kind of texture do they have?
Crystalline texture.
What is the texture of inorganic land derived sedimentary rocks?
what is the texture of all inorganic land derived sedimentary rocks
What is the relationship between an igneous rocks texture and where it 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.
What are rocks that have a glassy texture called?
Obsidian

What are some non examples of texture in rocks?
Texture in rocks is not the same as color or shape. Texture refers to the size, shape, and arrangement of mineral grains or crystals within a rock, while color refers to the outward appearance of the rock. Similarly, shape in rocks refers to their physical form or structure, and not the internal arrangement of mineral grains which defines texture.
Metamorphic rocks that do not separate easily into layers have a what texture?
Non-foliated Texture!
How does the texture of rocks differ?
The texture of rocks differs based on their formation processes and mineral composition. Igneous rocks typically have a crystalline texture, with interlocking mineral grains formed from cooling magma or lava. Sedimentary rocks often exhibit a layered or granular texture due to the accumulation and compaction of sediments. Metamorphic rocks may display a foliated or non-foliated texture, resulting from the alteration of existing rocks under heat and pressure, leading to the alignment of minerals or a more homogenous appearance.
