What do the law of

Question

superposition and the law of
inclusion have in common?
Both laws are about
the ages of intruding
rocks.
Both laws are about
matching fossils in
different areas.
Both laws give the
exact ages of rocks.
Both laws describe the
relative ages of rocks.

Answer 1

Both the law of superposition and the law of inclusion describe the relative ages of rocks.

• The law of superposition states that in undeformed sedimentary rock layers, the oldest layers are at the bottom and the younger layers are at the top.
• The law of inclusion states that any rock fragments that are included in another rock must be older than the rock in which they are included.

Both laws are used to determine the chronological order of geological events and help build a relative timeline of Earth's history.
