There is no single process that causes the layering of sedimentary rocks and the layers can be very thin laminae up to very thick beds. Usually the reason why one sees layering is either because there are colour-changes or compositional changes in the sedimentary rocks. I give some examples below.
Very thin layering can be formed by annually varying sediment input. In some lakes a summer- and a winter-layer form a couplet of layers that can be recognized by their differing colour. People use these so-called warves for absolute age dating of sediments.
Layering can also be due to changes in the input of sediment from coarser grained material to finer grained material or the other way round. There are also packages of sediments of sub-marine sediment flows called turbidites, which show a sorting of the grain sizes in each package and that might be stacked to very thick successions.
There are also bedding patterns that are believed to be driven by changes in the Earth's climate via changes in the orbital parameters of our planet, so-called Milankovich-cyclicity. In some marine sedimentary rocks it is possible to pick these cycles up as changes in colour or as changes in the fraction of carbonate present in the rock.
Another type of layering exists in "chemical sediments", these being the products of evaporation of seawater. In restricted basins that periodically fall dry there is a well-defined succession of different minerals precipitating as the water evaporates and one can fined these cycles as stacked layers of carbonate, gypsum, anhydrite, halite (rock salt) and sometimes other highly soluble salts.
What else can I help you with?
What rock cycle process causes many sedimentary rocks to have visible layers?
The rock cycle process that causes many sedimentary rocks to have visible layers is called sedimentation. This process involves the accumulation of sediments, such as sand, silt, and clay, in layers over time. As more and more sediments are deposited and compacted, the layers become more distinct, creating the visible stratification seen in sedimentary rocks.
Whats the process of change sedimentary rock into a metamorphic rock?
Sedimentary rock can be transformed into metamorphic rock through the process of metamorphism, which involves high temperature and pressure deep within the Earth's crust. This causes the minerals in the sedimentary rock to recrystallize and reorganize, resulting in the formation of a new rock with different properties. The original sedimentary layers may still be visible in the metamorphic rock, but they will have undergone significant changes.
What type of rock has visible flat layers?
Sedimentary rock, such as sandstone or shale, often has visible flat layers called strata that form from the accumulation and compression of sediments over time. These layers can be easily distinguished in sedimentary rocks due to their distinct horizontal orientation.
Why are sedimentary rocks formed in layers?
Sedimentation of transported weathered and eroded material is continuous, cyclical, or event based. New sediments are deposited on top of existing sediments, forming layers that may be visible in a sedimentary rock body.
When layers of sediments Are Squeezed Together To Form Rocks Is Called?
It is called sedimentary rock.

How can grains of sand become part of sedimentary rock?
the compaction and heat under the layers of the Earth causes this process to occur

How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
Could a rock with visible layers and no mineral crystals likely formed from lava Harding on earth surface?
A rock with visible layers and no mineral crystals is unlikely to have formed from lava hardening on the Earth's surface. Such characteristics suggest sedimentary processes, where layers accumulate over time from sediments being deposited and compacted. In contrast, igneous rocks formed from lava typically have a more crystalline texture, as minerals crystallize during the cooling process. Therefore, the rock in question is more consistent with sedimentary formation rather than igneous.
Is rock with visible layers and no visible mineral crystals likely to be formed from lava hardening on Earth's surface?
No, rock with visible layers and no visible mineral crystals is likely to be sedimentary rock, formed from the accumulation and consolidation of sediments like sand, mud, or organic material. Rocks formed from lava hardening on the Earth's surface, like basalt, tend to have a uniform texture and lack visible layers due to the rapid cooling process.
