States that younger rocks lie above older rocks if the layers have not been disturbed

• Law of crosscutting
• Law of superposition
• Relative Dating
• Unconformity

This is the age of rocks and geologic features as compared with other rocks and geologic features nearby.

• relative age

• absolute age

• superposition

• cross-cutting relationships

• inclusions

According to this Principle, in undisturbed rock layers, the oldest rocks are on the bottom.

• Superposition

• Original Horizontality

• Lateral Continuity

• Cross-cutting Relationships

• Uniformitarianism

What geologic principles(or law) is best displayed here? CHOOSE 2.

• Superposition

• Original horizontality

• Cross-cutting relationships

• Inclusions

What is the definition of Unconformity ?

• A record of the geologic events and life forms in Earth’s history
• The breakdown of a radioactive element, releasing particles and energy
• Fossils of widely distributed organisms that lived during only one short period.
• A place where an old, eroded rock surface is in contact with a newer rock layer

Which statement best describes the layers of rock in this picture?

• The layers would have been deposited as they are pictured, so nothing has happened to them.

• The layers have been disturbed since they would have been deposited horizontally .

• The layers are all the same age since they are all in the same location.
