UNIT QUIZ: Unit 13 Review Quiz

Take this quiz only after you've gone over the materials for this unit (Geologic Time and the Age of Earth).

This quiz contain 35 questions about the topics/ideas/concepts discussed in this unit and will be used to measure your understanding of these topics/ideas/concepts. Questions will be taken from both the readings and video resources presented in this unit.

You can take this quiz multiple times, but you'll need to get 80% or higher before you can proceed to the next unit. If you do not reach 80% on your first attempt, use it to identify your knowledge gaps (concepts from the video that you are still struggling to understand). Once you identify these gaps, go back to the reading and video materials and review these concepts BEFORE starting your second attempt at the quiz. Only the highest grade among all your attempts will be uploaded to the gradebook.

The essential learning outcomes for this unit are:

• Define geologic time and explain the difference between relative and numerical ages;
• Explain the key geologic principles used to decipher relative ages;
• Identify basic types of fossils and explain how they form;
• Sketch unconformities, explain how they form, and interpret what they represent;
• Describe the basis for correlating stratigraphic formations, and explain how correlation led to the development of the geologic column;
• Discuss how geologists determine numerical age by using isotopic dating;
• Explain the basis for establishing the geologic time scale and for determining the age of Earth;
• Describe the earliest life and how life evolution is linked to atmospheric evolution and geologic evolution;
• Identify key stages in the evolution of life through the Phanerozoic.
