Respuesta :
The formation of a clastic sediment and sedimentary rocks involves five processes:
1. weathering
2. erosion
3. transportation
4. deposition
5. lithification

Answer:
The correct answer is:
1) weathering of rocks
2) transport of the weathering products
3) deposition of the material
4) compaction
5) cementation
Explanation:
Sedimentary rocks are rocks formed from fragments of other rocks.
They are the product of the following processes:
- Weathering :
When the rocks are on or near the surface of the earth, they are exposed to the weathering process.
This process implies that the rocks and minerals that are on the earth's surface come into contact with the atmosphere, hydrosphere and biosphere.
The rocks disintegrate or decompose and fracture, facilitating the erosion process.
- Transport of the weathering products:
Once the rocks are fragmented in the weathering process, their transport begins.
The most important agent for this process is water, which moves from the smallest clay particles to the largest rocks.
As they are transported they continue to fragment even more.
Transport agents such as wind, glaciers and mass wear on the slopes also influence.
- Deposition of the material :
The largest materials or sediments that have survived the weathering process, thanks to having enough energy in the means of transport, are usually deposited near their source. They are deposited in the form of one layer over another horizontally.
- Compaction and Cementation:
While the sedimentation process continues, the materials that were already deposited before have an increasing overhead. This causes them to compact and expel the water they carried in the pores.
The dissolved minerals crystallize from the water in these pores and form mineral crusts, gradually cementing the sediments which results in the formation of a new rock.
In this way we can see how an original rock broke down, was transported and formed a new rock.
