Compare and contrast graded bedding and cross-bedding?
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.
Which features tells you how a sedimentary rock is layered?
The features that indicate how a sedimentary rock is layered include bedding planes, which represent the boundaries between different layers of sediment, and graded bedding, where grains are sorted by size within a layer. Additionally, cross-bedding can show inclined layers within a sedimentary rock, indicating the direction of sediment deposition.
What is the wavy line between layers of rock called?
The wavy line between layers of rock is called a "cross bedding." Cross bedding forms when sediments are deposited at an angle due to currents, resulting in distinct layers that intersect at an angle to the horizontal bedding.
How do you recognize an ancient turbidity current deposit now exposed in the mountain?
An ancient turbidity current deposit found in a mountain may be recognized by characteristic sedimentary structures such as graded bedding, cross-bedding, and lamination. These deposits often consist of fine-grained sediments that settled out of a high-energy underwater current. Additionally, fossils or paleocurrent indicators within the deposit can provide further evidence of its origin as a turbidity current.
5 types of sedimentary rock structures?
Bedding or stratification: Layers of sediment that are typically horizontal and represent different depositional events. Cross-bedding: Inclined layers within sedimentary rocks that are formed by the migration of sediment in a current. Ripple marks: Small-scale features on the surface of sedimentary rocks caused by the action of water or wind. Graded bedding: Layers with gradually changing grain sizes, typically indicating a decrease in the energy of the depositional environment. Concretions: Rounded masses of mineral matter that are often found in sedimentary rocks, forming within the rock after its initial formation.

Is it possible for a layer of cross bedding strata show graded bedding as well?
Absolutely: there are many possibilities. The only issue is that as the cross-bedding is often not on a massive scale, this may cause graded bedding to become unnoticeable. It is clearer in a rock with only graded bedding. As the beds are often quite shallow, grading is often unnoticeable, yet it still may exist on a slight scale.

What is planar bedding and cross bedding?
In planer bedding Surfaces are without cross lines, but cross-bedding is inclined.

What is the type of bedding that occurs depends upon the sediments method?
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.

What is trough cross-bedding?
A common variety of cross bedding. Generally at a relatively low angle it resembles scooped grooves. It is formed by sand dune migration (large or small scale)
What are An upward decrease in grain size in a single bed is known as?
Cross bedding
