select the correct answer from each drop - down menu. complete this passage about relative dating. barry is applying the principles of relative dating to a building that has been constructed. analyzing a section of the building, barry says that the lowest part of the section must have been constructed drop - down 1 the parts above it were constructed. he bases this conclusion on the principle of drop - down 2. also, looking at a crack in the building wall, he says that the crack must be drop - down 3 the wall. barry used the principle drop - down 4 to arrive at this conclusion.

Answer

Brief Explanations:

Relative - dating principles are used. The principle of superposition states that in an undisturbed sequence of sedimentary rocks or in a construction context, lower layers or parts are older and were constructed first. So the lowest part of the building section was constructed before the parts above it. For the crack in the wall, the principle of cross - cutting relationships is used. A feature that cuts across another is younger. So the crack must be after the wall was constructed.

Answer:

  1. before
  2. superposition
  3. after
  4. cross - cutting relationships
