Which of the following is a common plutonic igneous rock?
The most common plutonic igneous rock is granite. There are various types of granite based on whether the rock cooled above or below the surface of the earth. The major differences among these types of granitic rock is their crystalline structure.
What is grain according to geologists?
Grain refers to particle or crystal size in rock.
What else does rock texture include besides grain size and arrangement?
Grain shape.
What rock has the finest grain size?
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.
What is the Size of granite grain?
Granite is considered a coarse grained rock.

What is a small grain size rock?
clay
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 grain according to geologists?
Grain refers to particle or crystal size in rock.
What are 3 characteristics of a rock?
1.Grain Size 2.Grain Shape 3.Grain Pattern
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
What solidifies into plutonic rock?
magma
What else does rock texture include besides grain size and arrangement?
Grain shape.
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 is molten rock that squeezes into existing rock and cools?
A plutonic intrusion.Igneous rock.
Wind mostly erodes pieces of rock that are what size?
the size of a sand grain or smaller
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.
