This resource turns geological time scale into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.

The set includes questions like "What type of rock is primarily found in the Hadean Eon?", "What characterizes the Hadean Eon in terms of Earth's formation?", and "Which event is associated with the end of the Hadean Eon?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 26 pages in total

All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
