Clastic rocks are made from fragments of pre-existing rocks.
Clastic sedimentary rocks form from the breakdown of larger rocks through weathering and erosion. The resulting sediments are deposited and undergo compaction and cementation to form rocks like sandstone, shale, and conglomerate.
Organic sedimentary rocks, such as coal and some types of shale, form from the buildup and compression of plant material over time. These rocks are primarily composed of remains of plants and organic material.
Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.

Clastic rocks are made from fragments of pre-existing rocks.
Sedimentary rocks that form from the breakdown of larger rocks are called clastic sedimentary rocks. These rocks are created when fragments of pre-existing rocks, known as clasts, are weathered and eroded, then transported, deposited, and lithified through processes such as compaction and cementation. Common examples include sandstone, shale, and conglomerate, each varying in grain size and composition depending on the source material.
Organic sedimentary rocks, such as coal and some types of shale, form from the buildup and compression of plant material over time. These rocks are primarily composed of remains of plants and organic material.
Yes, through the process of erosion, transportation, deposition, and lithification, sediments from existing sedimentary rocks can be weathered and broken down to form new sedimentary rocks. The cycle of sedimentary rock formation can involve the breakdown and reformation of older sedimentary rocks.

Sedimentary rocks are formed from the weathering and erosion of pre-existing rocks. This process involves the breakdown of rocks into small particles that are then compacted and cemented together to form sedimentary rocks such as sandstone, shale, and limestone.
Sedimentary rocks form from a few different things. Sedimentary rocks form from sediment is deposited out of air, ice, wind and gravity.
