Question

question 9
step 12 in figure above is the__________.
fault
fold
brown layer
nonconformity
angular unconformity
red layer
pink layer
disconformity

Explanation:

A nonconformity is a type of unconformity where sedimentary rocks overlie igneous or metamorphic rocks. In geological diagrams, it is often represented as a boundary between different rock types (here, likely between the sedimentary layers above and the igneous/metamorphic - like rock below). A fault is a fracture with displacement, a fold is a bend in rock layers, angular unconformity has tilted layers below, disconformity is between parallel sedimentary layers. The red layer is just a color - described layer (not a geological structure name in the context of unconformities etc. as a key term here). The brown layer is also just color - based. The pink layer is color - based.

Answer:

Nonconformity
