UNIT QUIZ- Earth System

CLASS PERIOD

• 3rd
• 5th
• 6th
• 7th

The maximum concentrations of ozone are found in the:

• mesosphere.
• troposphere.
• exosphere.
• stratosphere

Which statement best compares relative dating and absolute dating?

• Relative dating determines the order of prehistoric events, and absolute dating determines the order of present day events.
• Relative dating estimates the age of materials in comparison to the rock layers around it, and absolute dating determines a more exact age of materials.
• Relative dating determines the exact age of minerals and absolute dating determines the exact age of fossils.
• Relative dating estimates the age of organic materials, and absolute dating estimates the age of inorganic materials.

Which statement about the species of animals and plants that existed on Earth in the past is best supported by the fossil record?

• Most became extinct.
• Most lived on land.
• Most were preserved in metamorphic rock.
• Most appeared during the Cambrian time period.

Which of the following is used in relative age dating?

• Carbon-14
• Radioactive Decay
• Principle of Superposition
• Potassium-Argon Dating

According to the timeline, what most likely led directly to the appearance of the first birds during the Jurassic Period?

• The evolution of dinosaurs
• The appearance of the first reptiles
• The appearance of the first flowering plants.
• The minor extinction during the Triassic Period.

How does the geologic time scale support the theory of evolution?

• It suggests that new life forms emerged and then changed over time.
• It suggests that some organisms have a higher level of fitness than others.
• It suggests that life forms evolve in response to changing environmental conditions.
• It suggests that massive extinction events result from the diversification of organisms.

What can be learned by studying the Earth’s history?

• We can see how climate has changed over time in natural ways to make predictions about the future.
• We are able to see what past life forms existed, how they changed over time and what might have caused them to go extinct.
• We are able to study past tectonic events and how they affected the area around them.
• We are able to learn about all of the above events listed to help us understand what future changes may take place on our planet.

Which of the following is used in absolute age dating?

• Radiocarbon dating
• Stratigraphy
• Superposition
• Cross-cutting intrusions

Why is the "Law of Superposition" critical to the study of fossil life forms?

• It allows us to time-sequence fossils
• It tells us that organisms are usually replaced by more highly-adapted ones
• It states that heavier rocks are on the bottom and light rocks rise to the top
• It specifies that each layer of rock is a different type of mineral
