• igneous intrusion

Which of the following statements is FALSE about cross-cutting relationship?

• A fault is always younger than the rock it breaks

• Rocks above an igneous intrusion is always younger

• Igneous extrusion is oldest than other rock layers

• An igneous intrusion is younger than the rocks it intruded

Why does a parent radioactive isotopes decays into a daughter isotope?

• because it is unstable

• because it is stable

• because it is used for relative dating

• because it is used for absolute dating

statements is TRUE?

• The top layer is the oldest.

• The rock inclusion is the oldest.

• The bottom layer is the oldest.
