texture
The Wentworth scale measures the grain size of sedimentary rocks, which refers to the diameter of the particles that make up the rock. The scale categorizes sediment grains into different size classes ranging from boulders to clay particles.
The Wentworth scale of grain size measures the average diameter of particles in sedimentary rocks, ranging from clay (less than 0.002 mm) to boulders (more than 256 mm). It helps geologists classify sedimentary rocks based on the size of the particles they are composed of.
The size of the grains in a sedimentary rock can be determined by examining the texture of the rock. Coarser grains indicate a larger grain size, while finer grains indicate a smaller grain size. Other features that can provide clues to grain size include the sorting (uniformity of grain sizes) and rounding of the grains.
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
The fundamental sedimentary rock unit is called a "bed." It refers to a layer of sedimentary rock that is distinguishable from the layers above and below it based on characteristics such as composition, grain size, and sedimentary structures. Beds are building blocks of larger sedimentary structures like formations and sequences.

The Wentworth Scale commonly measures grains of boulders, cobble, gravel, pebbles, sand, silt, clay and calloid.
The Wentworth scale of grain size measures the average diameter of particles in sedimentary rocks, ranging from clay (less than 0.002 mm) to boulders (more than 256 mm). It helps geologists classify sedimentary rocks based on the size of the particles they are composed of.
The Wentworth scale measures the grain size of sedimentary rocks, categorizing particles based on their diameter. It ranges from clay (less than 0.002 mm) to boulders (greater than 256 mm), providing a standardized way to classify sediments. This scale helps geologists understand the depositional environment and processes that formed the sedimentary rock.
The Wentworth scale measures the grain size of sedimentary rocks, categorizing sediment particles based on their diameter. It ranges from very fine silt (less than 0.0625 mm) to boulders (greater than 256 mm), providing a standardized method for classifying sediments. This scale helps geologists understand the depositional environment and the processes that formed the sedimentary rock.
An arenite is a sedimentary rock with a grain size in the sand range on the Wentworth scale.
No, sedimentary rocks are classified based on their grain size, composition, and texture, not by whether they are foliated or nonfoliated. Foliation is a feature typically found in metamorphic rocks, not sedimentary rocks.
texture
The rock with the finest grain size is typically shale. Shale is a sedimentary rock composed of clay particles that are less than 1/256 millimeter in diameter, giving it a very fine texture. This fine grain size allows shale to split easily into thin layers, which is a characteristic feature of the rock.
Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.
Grain refers to the weight of the bullet when measured on a powder scale.
