History of Earth review

What evidence would a scientist use to determine the age of rock in a layer?

• index fossils
• living fossils
• resin fossils
• trace fossils
  

The diagram shows rock layers taken from two different locations that may be far apart from each other.What can be concluded based on the diagram?

• Location 1 has terrestrial fossils, and Location 2 has aquatic fossils.
• The layers in Location 1 are much older than the layers in Location 2.
• The layers in Location 1 are younger than the layers in Location 2.
• Layers from both locations with similar fossils are about the same age.
  

The diagram shows a section of land that has been undisturbed and includes a fossil.What can be concluded about the fossil?

• It is younger than the limestone.
• It is older than the shale.
• It is approximately the same age as the limestone.
• It is approximately the same age as the sandstone.
  

The image shows fossils found in a section of sedimentary rock.In which layer are the oldest fossils found?

• Layer A
• Layer B
  
• Layer C
• Layer D
  

Which statement can be best supported by the fossil record?

• Most of the organisms on Earth have not changed over time.
• Most life forms that existed on Earth are now extinct.
• Humans and dinosaurs have existed on Earth at the same time.
• Human have lived on Earth for most of geologic history.
  

Which condition best supports fossil formation?

• A dead organism is eaten by scavengers and shredded.
• A dead organism is slowly decomposed by bacteria and insects.
• A dead organism is washed away in a flood and buried under rocks.
• A dead organism is quickly buried under mud and sand.
