What are the three types of unconformities, and what is each missing? What will be an ideal response?

Question 2

What do unconformities represent? What will be an ideal response?

Answer to Question 1

Disconformities are a surface of erosion or nondeposition separating younger from older rocks, both of
which are parallel to one another. An angular unconformity is an erosional surface on tilted or folded
strata over which younger strata are deposited. The strata below the unconformable surface generally
dip more steeply than those above, producing an angular relationship.

Answer to Question 2

Unconformities represent missing time; the geological record is not complete at an unconformity. In a
sequence of sedimentary rock layers, some rock may be missing due to nondeposition, erosion, or
both, and this means that that time period is not represented. A nonconformity is an erosional surface
cut into metamorphic or igneous rocks and covered by sedimentary rocks. The principle of inclusions
can be used to determine the relative ages of the igneous (or metamorphic) and sedimentary rocks
