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.
The process by which layers of sedimentary rock are formed is called strata.
Maybe Sedimentary Rocks?
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.
Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.
Yes.

the compaction and heat under the layers of the Earth causes this process to occur

Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.

Sedimentary rock layers. your welcome
The layers in sedimentary rocks are called strata.
temperature and time or deposition and melting or collection and transportation or time and pressure
Minerals cause the layers - each mineral has a certain color (and hardness).
