Help your students build real understanding of what explains crustal ages through ninety questions that move from basic recognition to genuine reasoning about how the Earth works.
Sample questions include "What does the presence of fossils in rock layers indicate?", "What is the significance of isotopic ratios in dating rocks?", and "What is a primary method for dating sedimentary rock layers?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned earth science unit. The unit also covers Crustal Age Patterns, Mid Ocean Ridges and Age, Radiometric Dating as a Tool, Plate Tectonic Movements, Engaging in Argument, and Continental Shield Crust, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS1-5.
