4. sedimentary structures can tell geologists a lot about past environments. cross bedding is among the more common and useful of these structures. what is crossbedding? what does it tell us about the environment the rock formed in?

As explained below.

Explanation:

Sedimentary rocks ar he secondary rocks to form over the earth due to the competition and solidification of sediments in various layers of rocks. In geologically cross-breeding is the cross-stratification of the rocky mass layering which is aligned to the angle of the bedding plane. It forms depositional of the inclined surfaces such as triples and dues. And is indicated by the depositional environment of the earth like the deltas. The cross-bedding tells the geologist of the area's historical significance and the conditions in which the present landscape has evolved. Other sources being the internal sorting patterns and Geometries like the tabular horizontally extended beds and the cross-beds formed by the inclined base of the rocks. An example of the phenomenon is cross-bedding in the Waddens Cove formation of Nova Scotia.
