The texture of a rock depends on the minerals and/or fossils it contains, as well as the processes the components of the rock went through when it was form. For example, a pumice rock (the one that has a lot of holes) has its texture because the magma that form it lost a lot gas, and while the gas escaped the holes started to form. On the other side, some sedimentary rocks have a lot fossils which gives them their specific texture as well as sedimentary rocks can have ripples which means the sediments that constitute that rock were joint together in a beache where waves were moving constantly. The shape of these waves can tell geologists the direction of the current when the rock was formed.
Grain
yes
Grain
A texture that gives the rock a layered appeareance.
a foliated rock is a metamorphic rock with a texture that gives the rock a layered appearance.
The sizes,shapes,and positions of the grains that make up a rock.
Slate rock has a fine-grained texture, with individual mineral grains that are too small to be seen with the naked eye. This gives slate a smooth and dense appearance.
Gneiss rock typically has a coarse texture due to its mineral composition of interlocking grains of quartz, feldspar, and mica. This gives it a banded or foliated appearance, with distinct layers or bands of different mineral compositions.
The word that describes the shapes and sizes of grains in a rock is "texture." Texture refers to the arrangement and size of mineral grains in a rock, whether they are fine-grained, coarse-grained, or other specific characteristics.
no texture
well it depends. if its agray rock, it has a gray texture. if its a gold rock, it has a high value texture. etc
The size of the mineral crystals in an igneous rock determines the rock's texture.
