Respuesta :

Superposition of strata

Younger

Cross-cutting relationship

Explanation:

Barry says the lowest part of the section must have been constructed  before the parts above it based on the principle of superposition of strata.

Using the cracks, the cracks are younger than the wall; Barry used the principle of cross-cutting.

  • Relative dating places rock strata based on geologic event.
  • Several principle guides the application of this dating method.

According to the principle of superposition "in an undeformed sequence of rock strata, the oldest layer is at the bottom and the youngest on top".

The principle of cross-cutting states that "intrusion and faults are younger than the rocks they cut through".
