The degree of vertex D is if it is an indegree or outdegree, it is 1 degree in vertex D.
You could identify a sedimentary rock as a conglomerate because it consists of rounded fragments from pre-existing rocks that are larger than 4 mm. They often are found setting in finer-grained sedimentary matrix rocks. An example of conglomerate rocks are Breccia conglomerates which are rocks that have an angular and rounded clast.
I believe the answer would be A. Diffusion is "the spreading of something more widely" Which fits in with this.
Answer:
The correct answer is D. Synonymous with craton
Explanation:
Craton is referred to as a large immobile block of earth crust composed of ancient crystalline basement rock and have deep lithosphere roots that extends deeply into the earth's mantle.
Cratons are often seen as shields because the basement rock crops out at the surface, and in platforms, the basement is overlaid by sedimentary rock.
Geographically, a shield and a surrounding platform together are synonymous with craton.
