Grains the particles of minerals or other rocks that give a rock its texture
Texture is the word used to describe a rock's constituent mineral size and arrangement, visible on a freshly fractured surface. Because a rock's surface can be weathered to a smooth or polished surface, the way it feels is not usually included in a description of texture.
The basic division of sedimentary rocks is into clastic and chemical rocks. Clastic rocks are formed when grains form a sediment and are then cemented together, as happens with sandstone or shale. Chemical rocks form when solid precipitates out of solution, for instance when calcium carbonate is formed from sea water to give chalk.
Recipes for diabetes don't have to be bland or tasteless. They are low in carbs and fat, but don't have to be low in flavor. Whole grains and spices give foods more texture and are healthy to eat.

Difference in temperature of the varying layers of the Earth's surface where either of the rocks solidify,causes difference in size of grains of rocks.When solidified below the Earth's surface,the grains are comparatively larger crystals than extrusive igneous ones.Intrusive rocks form underneath the Earth's surface(eg.,granite). Magma cools slowly so it has time to form large crystals.Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form(eg.,obsidian).

Rocks can add colour, and texture to a drawing or painting as well as help to establish the edges of areas. To draw a convincing rock it is advisable to spend some time looking at rocks in nature. The basic shape of a rock is a variation on a sphere. Learning to draw, shade and shadow a sphere with give you the building blocks to draw realistic rocks. After that it is just practice, practice, practice.
