Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.
The grains of a rock are the individual mineral particles that make up the rock's composition. These grains can vary in size, shape, and color, depending on the type of rock and the process by which it was formed. Fine-grained rocks have smaller grains, while coarse-grained rocks have larger grains.

When all the grains in a rock are easy to see the rock is described as what?
Visible crystals or grains would be referred to as a coarse grained texture.
What rock has interlocking grains with no specific pattern?
A rock that has interlocking grains with no specific pattern is known as a non-foliated rock. Examples include quartzite and marble. These rocks form from the recrystallization of minerals under high pressure and temperature conditions, resulting in interlocking grains without a preferred orientation.
What is a rock with long flat mineral grains?
A rock with long flat mineral grains is likely to be schist. Schist is a metamorphic rock characterized by its foliated texture, with mineral grains aligned in a parallel fashion, giving it a distinct layered appearance.
Is sandstone igneous or sedimentary or metamorphic?
Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains themselves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from.
What is the size shape and position of grains that make up a rock called?
The size, shape, and arrangement of grains in a rock is known as its texture. Grains can vary in size from fine (small) to coarse (large), and can be rounded or angular in shape. The position of grains within a rock can be random or show preferred orientation.
What gives rock it's texture?
The sizes,shapes,and positions of the grains that make up a rock.
How do you see rock grains on a rock?
You can see rock grains on a rock by examining its surface closely. Grains may appear as small, distinct particles of various colors and sizes. The use of a hand lens or magnifying glass can help to enhance the visibility of individual grains.
When all the grains in a rock are large easy to see the rock is describe as?
When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
When all the grains rock are large and easy to see the rock is describes as?
When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
When all the grains in a rock are large and small to see the rock is described as what?
When all the grains in a rock are large and small to see, the rock is described as having a bimodal grain size distribution. This means that the rock contains both large and small grains, with little to no medium-sized grains present.
Does granite have rounded grains?
Granite does not have rounded grains but contains interlocking grains. An example of a rock with rounded grains is a sandstone.
What type of grains does metamorphic rock have?
Metamorphic rocks can have various types of minerals, such as quartz, feldspar, mica, and amphibole, which form grains within the rock. These grains can be elongated or flattened, depending on the degree of metamorphism the rock has undergone. The size, shape, and alignment of these grains provide valuable information about the rock's history and the conditions under which it formed.
When all the grains in a rock are easy to see the rock is described as what?

A rock with long flat mineral grains is likely to be schist. Schist is a metamorphic rock characterized by its foliated texture, with mineral grains aligned in a parallel fashion, giving it a distinct layered appearance.
What Tiny grains eroded from rock?
We call them clastic rock also referred to us the sedimentary rock.
