Sedimentary rock can form in more than one way. The bulk of sedimentary rock is clastic sedimentary rock, formed from the weathering and erosion of existing rock. The steps in its formation are listed below. Numbers 4 and 5 are often listed together as the process of lithification. For further explanation of sedimentary rock formation, see the related question below.
- Weathering of pre-existing rock into smaller pieces.
- Erosion and transportation of weathered rock particles (sediments).
- Deposition of eroded sediments.
- Compaction of deposited sediments.
- Cementation of compacting sediments.

What are examples clastic sedimentary?
Sandstone, conglomerate, and breccia are examples of clastic sedimentary rock, composed of particles of other rocks.
Sedimentary rocks formed from broken fragments of other rocks are?
These are known as clastic or detrital sedimentary rocks. Depending on the size of the clasts they may be claystones (< 4 micro m), siltstones (grain size between 4 and 64 micro m) or sandstones (grain size between 64 micro m and 2 mm). If formed of angular fragments larger than 2mm in a finer grained matrix, this type of rock is known as a breccia. If the fragments are rounded, and larger than 2mm then it is a conglomerate.
What are the 4 ways that geologists classify rocks?
texture,size,show,and colour
What is the 4 step process that forms sedimentary rock?
The four stages of sedimentary rock origins are weathering, transportation, deposition, and compaction/cementation. Sedimentary rocks are formed from other parts of rocks and after going through the four stages form a sedimentary rock.The first phase is weathering, which is when the rocks are exposed to elements in the atmosphere. Then more specifically it is either chemically or mechanically weathered. When a rock is chemically weathered it is broken down by some type of chemical reaction and can go through processes such as oxidation, hydrolysis, or carbonation. When a rock is mechanically weathered it does not go through a chemical change, but rather is physically broken apart such as built up pressure from the earth's movement. These rock parts become the basis for the journey the sediments are about to embark in order to form a sedimentary rock.The next phase is transportation, because after being broken the parts must then travel to become a larger rock. They can be transported by many elements such as water or wind. Larger particles take larger amounts of energy to be transported.The next phase is deposition. This is the end of their transportation for the most part, when the momentum becomes too low to continue transporting and is thus deposited. After it is transported it begins to form the characteristics of the rock by adapting to the location's attributes chemically, biologically, and physically. They gain these attributes in their final formation.The last step is compaction and cementation. The layers of the newly forming parts of the rocks begin to come together to form the sedimentary rock. They become bonded together by the pressure from each of the particles, which releases moisture from the compaction to cement them together. This then forms a sedimentary rock.

What are the 4 types of sedimentary rocks?
There are only 3 types of sedimentary rocks and they are...Clastic RocksChemical RocksOrganic rocks
What are four stages in the formation of sedimentary rock in chronological order?
The four stages in the formation of sedimentary rock always proceed in the same order. This order is 1. Weathering of rocks, 2. Erosion by wind and water carry the products of weathering to a new place, 3. Compaction, 4. Cementation.
4 kinds of sedimentary rocks?
Limestone, sandstone, mudstone and chalk.
What are 4 sedimentary rocks?
Sandstone, limestone, shale, gypsum, & conglomerate
What are the main things about sedimentary rock?
Usually, sometimes sedimentary rocks can be found creating on the side of pool's. And even though sedimentary rock is small, they can be used for big thing. Like houses, or even sculptures. 6 billion years ago when the earth was forming there were no Sedimentary rocks, as well as metamorphic, but there were igneous rocks. It was 3.9 billion years ago when the first sedimentary rocks began to appear!
What are the 4 main rocks of sedimentary rock?
limestone brittle carna reno calum
What are the three types of rock and their formation?
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
What are the main thing about rocks?
Sedimentary rocks are; 1. Stratified. 2. Composed of Fossils.. 3. Non-crystalline. 4. Generally less resistant to weathering.
Is'nt the sedimentary rocks are form of pressure and heat?
No, sedimentary rocks are not formed from pressure and heat. They are formed from the accumulation and compaction of sediments, such as sand, silt, and clay, over time. Pressure and heat are more commonly associated with the formation of metamorphic rocks.
How are metamorphic rocks formed Tell it in a way that a grade 4 can understand it?
Basically a bunch of rocks come together( are pressed together by heat and pressure) in a process called Lithification , those rocks can be either Sedimentary or Igneous rocks.
What is the sequence of events that form clastic sedimentary frocks from solid rocks?
The formation of a clastic sediment and sedimentary rocks involves five processes: 1. weathering 2. erosion 3. transportation 4. deposition 5. lithification
Science note-taking 6 grade worksheet answers?
