Select the types of unconformities seen in rock strata.
A
disconformity
B
nonconformity
C
angular unconformity
D
angular discontinuity
Explanation: 

Detailed explanation-1: -Nonconformity: develops where sediments are deposited on top of an eroded surface of igneous or metamorphic rocks. Paraconformity: strata on either side of the unconformity are parallel, there is little apparent erosion. Angular unconformity: strata is deposited on tilted and eroded layers (such as at Siccar Point)

Detailed explanation-2: -There are three kinds of unconformities: disconformities, nonconformities, and angular unconformities.

Detailed explanation-3: -An angular unconformity is a type of unconformity in which younger flat rock layers were deposited over older tilted, eroded rock layers.

Detailed explanation-4: -An angular unconformity is an erosional surface that truncates older, tilted sedimentary layers and that is overlain by younger layers, oriented parallel to the unconformity.

Detailed explanation-5: -ANGULAR UNCONFORMITIES. DISCONFORMITIES. NONCONFORMITIES.
