Stratification.
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.
Sedimentary rocks, such as sandstone or shale, erode to expose layering due to the distinct horizontal beds created during the deposition process. The layering, or bedding, in sedimentary rocks forms as sediments settle and accumulate over time, preserving a record of the Earth's past environments and processes.
Layering in sedimentary rock is due to seasonal or event based deposition of small rock particles which reflect the environment at the time of deposition. Layering in metamorphic rocks (foliation) is due to the realignment and alteration of minerals from heat and pressure.
Sedimentary rock forms from the layering of eroded rock material, which accumulates and undergoes compaction and cementation over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
In undeformed strata, the rocks are typically the densest at the bottom of the sequence. This is due to the process of gravitational settling, where denser rocks sink and accumulate at the bottom over time, creating a denser layering pattern in the strata.

The layering in sedimentary rocks is called stratification. This process occurs as sediments are deposited over time, accumulating in horizontal layers that can vary in composition, color, and thickness. Stratification reflects changes in the environment and conditions under which the sediments were deposited, providing valuable information about Earth's history.
Sedimentary Rocks. Sedimentary rocks are created from stratification by the layering of materials on one another which then get compacted and cemented by sedimentation process over long period of time. The whole process of formation of sedimentary rocks from sediment is called Diagnesis. Examples of sedimentary rocks are limestone, chalk, and sandstone.
Metamorphic Rocks
Layering in sedimentary rock is due to seasonal or event based deposition of small rock particles which reflect the environment at the time of deposition. Layering in metamorphic rocks (foliation) is due to the realignment and alteration of minerals from heat and pressure.
They are called sedimentary rocks.
Sedimentary rock forms from the layering of eroded rock material, which accumulates and undergoes compaction and cementation over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
The idea that rocks form over long periods through slow geologic processes is called the rock cycle. This process involves the continual transformation of rocks from one type to another through processes like weathering, erosion, and lithification.
In undeformed strata, the rocks are typically the densest at the bottom of the sequence. This is due to the process of gravitational settling, where denser rocks sink and accumulate at the bottom over time, creating a denser layering pattern in the strata.
Stratification refers to the layering of sediments and rocks based on differences in composition or grain size. It occurs as sediments are deposited over time by processes like water or wind, with each layer representing a distinct period of deposition. These layers can provide valuable information about the Earth's history and environmental changes.
Sedimentary rock, such as sandstone or limestone, typically shows a pattern of layering due to the deposition of sediments over time. Each layer represents a different period of deposition, providing insights into the Earth's history and environmental conditions.
