Sediments are deposited in large, continuous sheets in all lateral directions.

• Original horizontality

• superposition

• lateral continuity

• inclusion

• cross-cutting relationship

If one geologic feature cuts across another feature, the feature that cuts across is older.

• Original horizontality

• superposition

• lateral continuity

• inclusion

• cross-cutting relationship

Most rock-forming materials are deposited in horizontal layers.

• Original horizontality

• superposition

The K-Pg boundary is the layer of iridium that was left when an asteroid hit Earth. Scientists believe that this caused the dinosaurs to become extinct. What evidence could scientists find to prove their theory?

• Iridium is naturally found on the Earth and is not found in asteroids. There are no dinosaur fossils found above the K-Pg boundary.

• Iridium is not naturally found on the Earth, but is found in asteroids. There are no dinosaur fossils found above the K-Pg boundary.

• Iridium is not naturally found on the Earth, but is found in asteroids. There are a lot of dinosaur fossils found above the K-Pg boundary.

• There is no evidence

What could cause the layers in a geologic column to be out of order?

• Fossils are never out of order

• Fossils decided one day to switch the order

• Since the fossils are out of order, there must have been a minor geologic events such as erosion.

• Since the fossils are out of order, there must have been a major geologic event such as mountain building or tectonic plate subduction to change the order.
