In geology a bed is the smallest division of a geologic formation or stratigraphic rock series marked by well-defined divisional planes (bedding planes) separating it from layers above and below. Concurrently the character of the bedding planes be they eroded, cemented, bored, bioturbated, or depositional surfaces is used to aid in the interpretation of these sedimentary rocks. Concurrently the character of the bedding planes be they eroded, cemented, bored, bioturbated, or depositional surfaces is used to aid in the interpretation of these sedimentary rocks. Bedding plane definition, the surface that separates one stratum, layer, or bed of stratified rock from another. See more.
Strata (singular: stratum) are the horizontal layers, or beds, present in most sedimentary rocks. During or immediately after the accumulation of sediments, physical, biological, and chemical processes produce sedimentary structures. Carboniferous limestone is a sedimentary rock formed in the Yorkshire Dales around 300 million years ago. These rocks were laid down on the sea bed and made up of layers of ancient corals and skeletons of sea creatures living in the shallow seas at that time. The tilted bedding planes of Sauratown Mountain are visible in this photograph. The quartzite layers that make up the pinnacle of Pilot Mountain also comprise the erosion-resistant cap rocks of Hanging Rock and the two ridges that separate these pinnacles.
Surface separating layers of sedimentary rocks. Each bedding plane marks termination of one deposit and beginning of another of different character, such as surface separating a sand bed from a shale layer. (geology), forms and spatial position of rocks in the earth’s crust. Sedimentary and metamorphic rocks usually occur in the form of layers or strata bounded by roughly parallel surfaces. Bedding, bedding planes: layering formed in sedimentary rocks as the rate of sediment deposition varies. Layer boundaries are called bedding planes.

The layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth s surface, as from lava flows and volcanic fragmental deposits. Planes of parting, or separation between individual rock layers, are termed stratification planes. These are cross-bedding, which is common in fluvial or eolian deposits, and graded bedding, which reflects transport by density (or turbidity) currents or, in certain cases, varved deposits. Geology humor!!!! – surface separating layers of sedimentary rocks and deposits. Each bedding plane marks termination of one deposit and beginning of another of different character, such as a surface separating a sandstone bed from an overlying mudstone bed.
