Classify relative dating
Free printable Grade 8 science worksheet for "Classify relative dating" — practice geologic time. No-prep, print or assign online.
Middle-school students classify concepts related to relative dating — such as superposition, cross-cutting relationships, and index fossils — in this challenging Earth and Space Science worksheet on Geologic Time. Teachers can use it to assess whether students can apply these principles to determine the relative age of rock layers and geological events. It fits within the Grades 6–8 geologic time sequence and supports scientific reasoning from physical evidence.
Learning objectives
- Classify relative dating principles (superposition, cross-cutting, index fossils) by type
- Apply relative dating principles to determine the sequence of geological events
- Explain how relative dating differs from absolute dating and when each is used
