Generally, grains of rocks and minerals can be any shape and is usually dependent on the type of erosion and/or weathering.
Type of erosion/weathering|Grain shape
None |Angular
Water |Round, Smooth
Wind |Round, Pitted
Glacial |Semi-round to Angular with parallel scratches
None |(As formed)
Physical |Angular
Chemical |(In solution)

What determines the grain shape of a rock such as conglomerate?
The mineral composition of the conglomerate determines the grain shape as well the the type of weathering or erosive elements (wind, water, chemicals) that the rock is is exposed to because grain shape is heavily dependent upon whether the rock has been subjected to erosion or not.
What determines the grain shape of a rock?
The grain shape of a rock is primarily determined by the rate at which the rock cooled and solidified. Rocks that cool slowly tend to have larger grains, resulting in a coarse-grained texture, while rocks that cool quickly have smaller grains, leading to a fine-grained texture. Other factors such as the mineral composition of the rock and the amount of pressure it was subjected to during formation can also influence grain shape.
What is the best definition for Sediment sorting layering texture and grain roundness?
Sediment sorting refers to the uniformity of grain size within a deposit, layering refers to the horizontal stratification of sediment, texture describes the size, shape, and arrangement of grains within a sediment, and grain roundness indicates the relative smoothness or angularity of sediment grains.
What is the grain shape for granite?
Granite typically has a coarse-grained texture, with interlocking crystals that are visible to the naked eye. The grains in granite are typically irregular in shape and can vary in size, depending on the specific mineral composition of the rock.
What is one piece of soil called?
A piece of soil is commonly referred to as a soil particle or soil grain. These individual particles can vary in size, shape, and composition.
What is the shape of rice grain?
the same shape as a poo
What are 3 characteristics of a rock?
1.Grain Size 2.Grain Shape 3.Grain Pattern
What is the grain shape of quartzite?
jagged
What else does rock texture include besides grain size and arrangement?
Grain shape.
What is pellet grain for horses?
Pellet grain is really just the type of shape of the grain. Instead of flake grain it is just shaped like a pellet or, if you will, like a perscriptian drug.
What are 3 characteristics of a rocks grain?
Three characteristics of a rock's grain include size (fine, medium, coarse), shape (angular, rounded), and sorting (well-sorted, poorly sorted). These characteristics can provide information about the rock's origin and history.
Is granite jagged?
Yes, granite's grain shape is jagged.
What is the grain shape of marble?
The grain shape of marble is typically interlocking. This means that the individual mineral grains in the marble are tightly interwoven or interlocked with each other, forming a solid and dense structure.
What shape are the quartz crystals in sandstone. are they isometric........ octagonal.........?
The crystal form is hexagonal, but the grain shape is rounded.
What is obsidians grain shape?
Obsidian typically has a smooth, glassy texture due to its quick cooling process when formed from volcanic lava. It has a conchoidal fracture pattern, which means it breaks with curved, shell-like shapes. The grain shape of obsidian is generally fine-grained due to its rapid cooling.
What shape is a grain silo?
A grain silo is typically cylindrical in shape. This design allows for efficient storage and easy unloading of grain, as the round structure helps facilitate the flow of grain towards the discharge point at the bottom. Some silos may also have conical or flat roofs, but the primary body remains cylindrical.
What can be determined by studying the shape of classic grains?
There is a few things that can be determined by studying the shape of classic grain. This is called the palynology study.
