Look for signs of banding or layering that would be evidence of sedimentary strata. Banding also occurs in metamorphic rocks, but the bands may be very distinct in color from one another. If the rock scratches with a knife, it may be sedimentary. High silica content in some igneous rocks may prevent scratching with a knife blade.

What kind of rock has layers and is made from small grain?
A type of rock that has layers and is made from small grains is sedimentary rock. Sedimentary rocks form when sediments such as sand, silt, or clay are compacted and cemented together over time. Examples of sedimentary rocks include sandstone and shale.
Is sandstone igneous or sedimentary or metamorphic?
Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains themselves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from.
What types of grains is sedimentary rock made from?
sand grains
What is the glue that holds sedimentary grains together called?
The glue that holds sedimentary grains together is called cement. Cement is usually made up of minerals like calcite, silica, or iron oxide that fill the spaces between sediment grains and bind them together to form a rock.
Is Mount Everest sand stone?
Mount Everest is made of sedimentary rocks such as shale limestone etc

Can coarse sedimentary rock be made up of pebbles or boulders?
Yes, coarse sedimentary rock can be made up of pebbles or boulders. Coarse sedimentary rocks are formed from the accumulation and cementation of larger grains, such as pebbles and boulders, that are transported by water, ice, or wind. These larger grains are typically found in rocks like conglomerate or breccia.
What is sedimentary rocks made of?
Sedimentary rocks are made out of sediments.
How are rocks and grains different?
Rocks are composed of one or more minerals, while grains are small, individual particles of a mineral. Rocks can be made up of different types of minerals and have a variety of sizes and shapes, while grains are typically uniform in composition and size. Rocks are larger and can be made up of multiple grains, whereas grains are individual, tiny fragments.
What types of grains is sedimentary rock made from?
sand grains
Why do some sedimentary rocks contain rounded grains and some not?
Sedimentary rocks with rounded grains typically form from materials that have been transported over long distances by wind, water, or ice, which causes abrasion and rounding of the grains. In contrast, sedimentary rocks with angular grains often form from materials that have not been transported far and have not undergone as much abrasion. Factors like the energy of the transporting agent and the distance traveled can influence the roundness of the grains in sedimentary rocks.
What is a sedimentary rock made of?
small solid pieces
What are the particles in sedimentary rocks called?
Sedimentary rocks are made from particles called sediment. They are made from layers of sediment (small particles) on the bottom of rivers or seas. The sediments are compressed as more layers build on top of them. The particles then become cemented together to form solid rocks. The layers of rock are called strata. Sedimentary rocks have a grainy structure and they easily crumble.
WHAT ARE two types of sedimentary rocks and describe what they are made from?
Two types of sedimentary rocks are sandstone and limestone. Sandstone is made from grains of sand that have been compacted and cemented together, while limestone is primarily made from the accumulation of the shells and skeletons of marine organisms.
Where is limestone made?
Like most other sedimentary rocks, limestone is composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.
What is the glue that holds sedimentary grains together called?
The glue that holds sedimentary grains together is called cement. Cement is usually made up of minerals like calcite, silica, or iron oxide that fill the spaces between sediment grains and bind them together to form a rock.
