The type of bedding that occurs depends on the sediment's method of deposition, which can vary based on factors like water energy, sediment size, and environment. For example, horizontal bedding typically forms in calm water settings where fine sediments settle evenly, while cross-bedding occurs in environments with stronger currents, such as rivers or dunes, where sediments are deposited at angles. Additionally, graded bedding can form from sediment-laden flows, where coarser material settles first, followed by finer particles. Thus, the sedimentary environment significantly influences the characteristics of bedding.
Sedimentary rock depends directly on the weathering process that occurs on Earth's surface. Weathering breaks down existing rocks into sediments that eventually form sedimentary rocks through processes like erosion, transport, and deposition.
Graded bedding forms when sediments settle out of a moving fluid in order of decreasing grain size. This typically occurs in environments like rivers, deltas, or deep-sea turbidity currents where strong currents transport sediment before it settles. Heavier grains settle first, followed by progressively lighter ones, creating distinct layers of different grain sizes within a sedimentary deposit.
The two processes that can change sediments into rocks are compaction and cementation. Compaction occurs when sediments are compressed by the weight of overlying sediments, reducing the pore space between particles. Cementation happens when minerals precipitate in the pore spaces, binding the particles together into a solid rock.
it is called a 'dike'
It occurs by more than one method
The layering that occurs in sedimentary rocks is called bedding or stratification. Bedding is formed by the deposition of sediments in discrete layers over time, while stratification refers to the overall layering pattern in a rock formation.
Horizontal bedding refers to a geological phenomenon where sedimentary layers are deposited in a nearly horizontal manner. This type of bedding typically occurs in calm environments where the sediments settle without significant disturbance or tilting. Horizontal bedding is commonly observed in areas like beaches, deltas, and river floodplains.
Frost heaving is the mass movement that occurs when sediments freeze and thaw. During freezing, water in the sediments expands as it turns to ice, pushing particles upwards. When the ice thaws, the sediments settle back down, causing the surface to move vertically over time.
When layers of small sediments stick together because of pressure, compaction occurs. :)

Cross-Bedding is a feature that occurs at various scales, and is observed in conglomerates and sandstones. It reflects the transport of gravel and sand by currents that flow over the sediment surface (e.g. in a river channel). sand in river channels or coastal environments. Graded Bedding means that the grain size within a bed decreases upwards.
The dropping of sediments by any agent of erosion is called deposition. This process occurs when the transporting capacity of the agent (such as water, wind, or ice) decreases, causing the sediments it was carrying to settle on the Earth's surface.
Sediments turn into rock through a process called lithification, which involves compaction and cementation. Compaction occurs when sediments are squeezed together by the weight of overlying layers, forcing out water and reducing volume. Cementation occurs when minerals dissolved in groundwater precipitate and bind sediment grains together to form solid rock.

To glue sediments together, a process of lithification occurs. This involves compaction under pressure, cementation by minerals like calcite or silica, and sometimes recrystallization. Over time, these processes solidify the sediments into sedimentary rocks.
