Sedimentary rocks are primarily made from the accumulation and compaction of mineral grains such as clay, silt, sand, and gravel. These grains are typically derived from the weathering and erosion of pre-existing rocks, as well as organic materials like shells and plant debris.

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 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 conglomerate a clastic rock?
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
Sedimentary rock composed of small grains of sand?
The sedimentary rock composed of small grains of sand is called sandstone. Sandstone forms when sand grains are compacted and cemented together over time. It is a common type of sedimentary rock found in various geological settings.
What is a sedimentary rock made up of rock fragments with round edges called?
conglomerate

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.
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 are the two types of crust and what type of rocks are they made of?
igneous rock and sedimentary rock
Is conglomerate a clastic rock?
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
What type of rock forms when small grains of rock are pressed together and become cemented?
Sedimentary rock forms when small grains of rock, such as sand or clay, are compressed and cemented together over time. Examples of sedimentary rock include sandstone and shale.
Sedimentary rock composed of small grains of sand?
The sedimentary rock composed of small grains of sand is called sandstone. Sandstone forms when sand grains are compacted and cemented together over time. It is a common type of sedimentary rock found in various geological settings.
What are standstones made of?
Sandstones are made out of sand sized particles or rock grains. Sandstones are clastic sedimentary rock. Some sandstone is composed of feldspar or quartz.
Is sedimentary rock made from solidified lava?
Rock that is formed from volcanoes are igneous rocks. Sedimentary rocks are formed from other layers of grains that are heaving and over millions of years have enough weight squish the grains into a proper rock. This is why the newest rocks are found at the top of layers.
What is a sedimentary rock made up of rock fragments with round edges called?
conglomerate
How can you tell if a rock made of small grains is igneou or sedimentary?
You can determine if a rock made of small grains is igneous or sedimentary by examining the arrangement of the grains. In igneous rocks, the grains are usually interlocking and crystalline, formed from the cooling of molten magma. In sedimentary rocks, the grains are typically rounded and loosely packed, resulting from the accumulation of sediments over time. Additionally, the presence of fossils or layering in the rock can indicate a sedimentary origin.
What type of rock would have grains cemented together?
That would be a sedimentary rock.
