Assume that you have just examined several flat-lying sedimentary layers. After much study you determine that there is a conside
rable span of time for which no sedimentary rock layer exists at this site. You have just discovered a(n) __________. a. angular unconformity
b. series of conformable strata
c. disconformity
d. example of cross-cutting relationships
Disconformity is a type of unconformity between parallel layers of sedimentary rock indicating interruption of sedimentation. It maybe caused by erosion or a period of no deposition. Therefore, on the site above the considerable span of time for which no sedimentary rock layer exists is an example of disconformity.
