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.


How does texture affect grain size in rock?

It doesn't. The grain size effects the texture. If a rock has a small grain size, it will have a smooth texture. If the grain size is large, such as pebbles, the texture will be rough. For example, siltstone is one of the smoothest rocks because it contains silt particles, which are .0004cm to .006cm. Conglomerate though contains various particles including cobbles and boulders, which are from 10cm to 100cm.


What is the grain property of rock fragments?

The grain property of rock fragments refers to the size, shape, and arrangement of mineral grains within the rock. It is important for determining the rock's texture and can provide information about the rock's formation history and the conditions under which it was formed. Grain size can range from fine (tiny grains) to coarse (larger grains), impacting the overall appearance and characteristics of the rock.


What feature of sedimentary rock is measured by the Wentworth scale of grain size?

texture


Does obsidian a glassy rock have a large grain size or a small grain size?

Actually, obsidian doesn't have grains at all. Technically obsidian is a glass, which means it has no internal structure. When geologists refer the the grain size of a rock, they mean how big the crystals that make it up are. Since obsidian has no crystals, it therefore has no grain size.
