Clastic rocks are composed of broken pieces of older rocks that have been broken up by the process of weathering and are therefore sedimentary in nature. The "clasts" (bits of older rock) may vary in size.
Clastic rocks are formed from the accumulation and cementation of fragments of pre-existing rocks and minerals, typically through processes like weathering, erosion, and deposition. In contrast, non-clastic rocks, such as chemical or organic sedimentary rocks, form through different processes, including the precipitation of minerals from solution or the accumulation of organic matter. While clastic rocks are primarily composed of solid particles, non-clastic rocks often involve chemical reactions or biological activity in their formation. This fundamental difference in formation processes leads to distinct physical and chemical characteristics between the two types of rocks.
Marble is neither clastic nor detrital; it is a metamorphic rock. It forms from the recrystallization of limestone or dolostone under heat and pressure. Clastic rocks are composed of fragments of other rocks, while detrital refers to sediments that are transported and deposited, which does not apply to marble's formation process.

Clastic and chemical rocks are both types of sedimentary rocks. They form from the accumulation and cementation of sediment particles. Clastic rocks are composed of fragments of pre-existing rocks, while chemical rocks form from the precipitation of minerals from water solutions.
The formation of clastic rocks involves three main steps: weathering, transportation, and lithification. Firstly, existing rocks undergo weathering, breaking down into smaller particles or sediments. These sediments are then transported by natural forces such as water, wind, or ice to new locations. Finally, lithification occurs as the sediments are compacted and cemented together over time, forming solid clastic rock.

Crystallization is not involved in the making of clastic rocks. Clastic rocks are formed through the accumulation and cementation of loose rock fragments, called clasts, through processes like weathering, erosion, transportation, and deposition. Crystallization typically refers to the formation of crystals from a liquid or gas, and is more commonly associated with the formation of igneous or metamorphic rocks.

Yes, sediment transport is a crucial process in the formation of clastic rocks. Clastic rocks are formed from the accumulation and lithification of sediments, which are typically derived from the weathering and erosion of pre-existing rocks. These sediments are transported by natural agents such as water, wind, or ice before being deposited in various environments, where they compact and cement over time to form clastic rock types, such as sandstone and shale.
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.
A major process in the formation of clastic sedimentary rock is lithification, which involves the compaction and cementation of loose sediment particles. These particles are typically derived from the weathering and erosion of pre-existing rocks. Over time, the layers of compacted sediment become solidified into rock through the process of lithification.

Weathering and erosion break down pre-existing rocks into sediments. Transportation of these sediments by water, wind, or ice to a new location. Deposition and compaction of the sediments to form layers, followed by cementation to create a solid clastic rock.
