Assume that you have just examined several flat-lying sedimentary layers. after much study you determine that there is a considerable 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

c. disconformity

Explanation:

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.

landlessness of ordinary people

^^something like that^^^

i believe this is
