It is called stratification.
Rock that erodes to expose layering is known as sedimentary rock.
Sedimentary 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.
Both rocks display foliation or banding although the processes involved in creating the foliations are different. Sedimentary rock layering occurs because of sediment deposition, and metamorphic foliation is a mineral alignment response to heat and directional pressure.
Look for signs of banding or layering that would be evidence of sedimentary strata. Banding also occurs in metamorphic rocks, but the bands may be very distinct in color from one another. If the rock scratches with a knife, it may be sedimentary. High silica content in some igneous rocks may prevent scratching with a knife blade.

Sedimentary rocks.
Rocks formed by layering.
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.
They are called clastic sedimentary 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.
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
Both rocks display foliation or banding although the processes involved in creating the foliations are different. Sedimentary rock layering occurs because of sediment deposition, and metamorphic foliation is a mineral alignment response to heat and directional pressure.
Sedimentary rocks are formed by the layering of materials, as new layers are added, they compress the lower layers which eventually physically adhere together.
The layers in sedimentary rocks are called strata.
