What sedimetary rock has the smallest grain size?
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
What is the main criterion for classifying detrital sedimentary rocks?
The main criterion for classifying detrital sedimentary rocks is the grain size of the particles they are composed of. Detrital sedimentary rocks are classified based on the size of the sediment particles, including categories such as conglomerate, sandstone, siltstone, and shale.
What lists the rocks in order of increasing grain size and increasing grade of metamorphism?
The list that orders rocks in increasing grain size and increasing grade of metamorphism is: shale (fine-grained) - slate (fine-grained) - phyllite (medium-grained) - schist (medium to coarse-grained) - gneiss (coarse-grained).
What clastic sedimentary rock has a very fine grain?
Siltstone is a clastic sedimentary rock with a very fine grain size, similar to sand but finer than sandstone. It is composed mainly of silt-sized particles and is commonly found in riverbeds, floodplains, and shallow marine environments where moderate energy deposition occurs.
Which features tells you how large the grains of a sedimentary rock are?
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.

What sedimetary rock has the smallest grain size?
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
What is the size of a shale rock?
Rocks don't come in particular sizes. Shale is a type of rock - it can be as small as a grain of sand or as large as a mountain range
What are a couple of examples of sedimentary rocks?
Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.
What turns sediment into shale?
Silt and clay size sediments form shale.
What is obsidian's grain size?

What is the grain size of dacite?
Small to medium grain size.
What is the name of a sedimentary rock usually based on?
Sedimentary rocks are typically classified based on their composition and grain size. Common names include sandstone (composed of sand-sized grains), limestone (composed of calcite or aragonite minerals), and shale (composed of clay-sized particles).
What term has the definition of grain size?
Particle size is another name for the term grain size.
What is the particle size of clastic sedimentary rocks?
Clastic sedimentary rocks are composed of particles ranging in size from clay (<0.004 mm) to boulders (>256 mm). These particles are derived from the weathering and erosion of pre-existing rocks, transported, and deposited to form clastic sedimentary rocks through processes like lithification.
What lists the rocks in order of increasing grain size and increasing grade of metamorphism?
The list that orders rocks in increasing grain size and increasing grade of metamorphism is: shale (fine-grained) - slate (fine-grained) - phyllite (medium-grained) - schist (medium to coarse-grained) - gneiss (coarse-grained).
