Children of Jewish heritage are usually given a Hebrew name for religious purposes and are sometimes also given a local language version of that name for secular purposes. By custom, Ashkenazi Jews (Jews of German or Eastern European descent) name their children after deceased relatives.
The notion of the general incompleteness of the geologic record is an important one to keep in mind while interpreting Earth history from the rock record. Types of Unconformities. There are three principal types of unconformity, namely, the disconformity, the nonconformity, and the angular unconformity [Fig. 1]. The disconformity (alternately referred to as the paraconformity) is an erosional surface which exists between and parallel to layers of parallel strata.
Click the image to see the animation. Use the movie controls to examine the stages. An unconformity is a gap in the sedimentary rock record. This animation shows the formation of an angular unconformityone where the layers above and below the unconformity are not parallel to each other, but form an angle. Examine how the final result allows you to infer the sequence of the rocks' formation.
