Sedimentary rock most often forms in the ocean through these processes:

1. Deposition of sediments such as mud, clay, sand, sea life secretions and marine life skeletons on the seafloor.

2. Compaction of these deposited sediments by the weight of continuing depositions of sediments. The crushing weight of further overlying sediments squeezes out the water that exists between sediment particles.

3. Cementation occurs when minerals form between sediment particles. The minerals are formed through a process called "precipitation". When the particles are cemented together in this manner, the resultant solid is a clastic sedimentary rock.

Why do clastic sedimentary rocks generally form underwater?

Clastic sedimentary rocks are generally formed underwater because water provides the necessary medium for the transportation and deposition of sediments. The energy from moving water helps carry and deposit the particles that eventually cement together to form clastic sedimentary rocks. Additionally, underwater environments offer a more stable setting for sediment accumulation compared to terrestrial environments.


What are the three categories of sedimentary rocks?

The three categories of sedimentary rocks are clastic, chemical, and organic. Clastic rocks form from the accumulation of weathered rock fragments, chemical rocks form from the precipitation of minerals from water, and organic rocks form from the remains of living organisms.


What do clastic and chemical rocks have in common?

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.


How are clastic sedimentary rocks different from organic sedimentary rocks?

they form


What type of sedimentary rocks form from the breakdown of larger 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.


How do clastic rocks form?

Clastic rocks are formed when a piece of a larger rock is broken off. Physical weathering is usually the way the piece is broken off.

Is it true that clastic rocks form when a rock fragment are squeezed together?

Yes, clastic rocks form from the accumulation and lithification of rock fragments (clasts) that have been eroded and transported by water, wind, or ice. These clasts are typically cemented together under pressure to form sedimentary rocks such as sandstone, conglomerate, and shale.


What type of sedimentary rocks form the breakdown of larger rocks?

Clastic sedimentary rocks form from the breakdown and erosion of larger rocks, through processes like weathering, transportation, and deposition. These sediments are then compacted and cemented together to form rocks like sandstone, shale, and conglomerates.


Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?

No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
