Is it possible for a layer of cross-bedded strata to 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.

∙ 10y agoI don't see why not, cross bedding just shows a current ripple, it seems entirely plausible that gravity settling could have occured on a small scale in the same bed.

What is another name for strata?
Layers or beds / bedding are other names for strata in geology.
What features tell you how a sedimentary rocked is layered?
Sedimentary rocks are often deposited in layers as strata. The feature that tells how a sedimentary rock is layered is called the bedding.
What process must ocurrs for an unformity to form?
first is erosion cause it wears away the land in the particular layer second is folding of strata and third is faulting of bedding plane forth is tectonic moment
What is the Geologic maps definition?
A geologic map or geological map is a special-purpose map made to show geological features. Rock units or geologic strata are shown by color or symbols to indicate where they are exposed at the surface. Bedding planes and structural features such as faults, folds, foliations, and lineations are shown with strike and dip or trend and plunge symbols which give these features' three-dimensional orientations.Stratigraphic contour lines may be used to illustrate the surface of a selected stratum illustrating the subsurface topographic trends of the strata. Isopach maps detail the variations in thickness of stratigraphic units. It is not always possible to properly show this when the strata are extremely fractured, mixed, in some discontinuities, or where they are otherwise disturbed.
What is the layer of sediment called?
It is called sedimentation.

What is a bedding plane?
A bedding plane is a geological term for the planar surface between adjacent strata.
What is the angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
What is the definition of bedding plane in geological view?
A bedding plane is the area of separation between rock strata made by a cyclical or situational deposition of sediment. Bedding planes are originally parallel to the horizon, but the strata inclination can be altered by crust moving events.
What is the definition angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
Which of the following best characterizes an angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
What is a possible explanation for why strata may be absent from outcrop?

What is graded bedding?
Graded bedding is a sediment deposit characterized by coarse sediments at its base, which grade upward into progressively finer ones. Graded beds generally represent depositional environments which decrease in transport energy as time passes, but also form during rapid depositional events. They are perhaps best represented in turbidite strata, where they indicate a sudden strong current that deposits heavy, coarse sediments first, with finer ones following as the current weakens. They can also form in terrestrial stream deposits.
