Which 2 groups is broken down into smaller groups by grain size?
Sedimentary rocks and igneous rocks can be broken down into smaller groups based on grain size. In sedimentary rocks, grain size categories include clay, silt, sand, and gravel. In igneous rocks, grain size categories include fine-grained, medium-grained, and coarse-grained.

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.
Which layers are composed of sediments of the largest grain size?
The top layer, known as the topsoil, is composed of the largest grain size sediments in soil. These sediments consist of sand, silt, and clay particles that have undergone weathering processes and accumulated on the Earth's surface.
Suppose sand gravel and clay are being carried by a river As the water enters a lake and slows down In what order will these sediments settle out of the water?
In this scenario, the gravel will settle out first, followed by the sand, and then the clay. Gravel has the largest grain size and weight, so it will settle out of the water column first. Sand will settle out next, followed by clay, which has the smallest grain size and weight.
What is a small grain size rock?
clay
Which has largest grain size sand or mud and clay?
Sand has the largest grain size compared to mud and clay. Sand particles range in size from 0.0625 mm to 2 mm, while mud and clay particles are much smaller, typically less than 0.002 mm in size.
What is clay soil's grain size?
Clay soil has a very fine grain size, with particles smaller than 0.002 mm in diameter. These tiny particles have a flat and plate-like shape, which contributes to clay soil's unique properties like high water and nutrient retention.
What is the smallest detrital grain?
Clay particles. Less than 2 micrometres in diameter.
What are four grain sizes in order from smallest to largest?
1)Clay-sized 2)Silt-sized 3)Sand-sized 4)Pebbles
Which 2 groups is broken down into smaller groups by grain size?
Sedimentary rocks and igneous rocks can be broken down into smaller groups based on grain size. In sedimentary rocks, grain size categories include clay, silt, sand, and gravel. In igneous rocks, grain size categories include fine-grained, medium-grained, and coarse-grained.
Which has the largest grain size the rocks made from mud clay or the ones made from sand?
Sandstone is the classification of rock composed of small rounded rock particles, usually quartz in nature.

What feature of sedimentary rock is measured by the Wentworth scale of grain size?
texture
What are the three grain sizes that make up soil?
The three grain sizes that make up soil are sand, silt, and clay. Sand particles are the largest, followed by silt which is intermediate in size, and clay particles are the smallest. These size differences affect soil properties such as water retention, drainage, and nutrient availability.
Which layers are composed of sediments of the largest grain size?
The top layer, known as the topsoil, is composed of the largest grain size sediments in soil. These sediments consist of sand, silt, and clay particles that have undergone weathering processes and accumulated on the Earth's surface.
Which feature of sedimentary rock is measured by the Wentworth scale of grain size?
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.
