Rock Strata

The idea that an earthquake is younger than the rock layer it cuts through is called ___________________.

• superposition

• intrusion

• extrusions

• cross cutting

Nicolas Steno came up with the Law of ________________ that puts the rock layers in order by age from youngest to oldest.

• superposition

• intrusion

• extrusions

• cross cutting

How do geoloists use the Geologic Time Scale when they are looking at rock strata?

Pick two.

• When earthquakes happen, they cut through the rocks.

• Geologists use the Law of Superposition. A stack of rocks has older rocks on the bottom and younger rocks on the top. Index fossils tell the age of the rocks.

• Index fossils tell the age of the rocks.

• Unconformity happens when older rocks meets younger rocks.

Identify J and G. Choose two answers.

• G shows intrusion where magma pushes through rock and cools.

• G shows extrusion because magam forces through rock strata to the surface of the rock.

• J shows unconformity because it is a wavy line where older rock meets younger rock.

• J shows crosscutting because it is an earthquake that cuts through the rock.

Choose a scientific explanation about major events in this area. Choose 3.

• M is a fault line where rock layers shift.

• L is a fault line where rock layers shift.

• S is unconformity where older rock meets younger rock.

• S is an earthquake because it is wavy.
