Does scoria have crystals or grain size?
Scoria typically has a vesicular texture with small gas bubbles, giving it a lightweight and porous appearance. It generally lacks visible crystals and instead features a glassy or fine-grained matrix. The grain size is usually very small, often classified as aphanitic, meaning the individual mineral grains are not easily distinguishable. Overall, scoria's texture is more characterized by its vesicles than by crystal size.
Is pumice has no grain?
Pumice is so fine grained, it actually doesn't have a grain--because it is a natural volcanic glass. The rough texture is caused by the vesicular nature of the rock--trapped pockets of gas bubbles with sharp glassy edges.
What else does rock texture include besides grain size and arrangement?
Grain shape.
What is the texture of cooling magma?
Cooling magma can have a variety of textures, depending on factors like mineral content, cooling rate, and the specific type of magma. Common textures include aphanitic (fine-grained), phaneritic (coarse-grained), porphyritic (mixed grain sizes), glassy (amorphous), or vesicular (with gas bubbles). Each texture provides clues about the conditions under which the magma cooled and solidified.

How does texture affect grain size in rock?
It doesn't. The grain size effects the texture. If a rock has a small grain size, it will have a smooth texture. If the grain size is large, such as pebbles, the texture will be rough. For example, siltstone is one of the smoothest rocks because it contains silt particles, which are .0004cm to .006cm. Conglomerate though contains various particles including cobbles and boulders, which are from 10cm to 100cm.
Are all rocks have the same texture and grain size?
no
What Is Wood Grain?
Wood grain is the rough texture in wood that is made out of tiny little gaps and holes in the wood. It is caused by the way the tree grows: in rings which are produced once a year.
