What type of rock/s usually undergo cross- cutting on rock layers?

• Igneous Rock

• Stratified Rock

• Sedimentary Rock

• . Metamorphic Rock

Why is there a need for correlation of rock layers?

• It provides information that the rock layers are connected to each other long ago.

• Fossils embedded in the rock layers serve as a proof of their correlation.

• It gives the relative age of the rocks.

• All of the above
