About this app
How Old Is This Rock is an interactive geology learning app covering absolute dating, relative dating, and geological eras. Explore half-life with Carbon-14, Potassium-40, and Uranium-238, infer rock order from layers and intrusions, and identify eras using index fossils. Mission-based activities guide learners through each concept with adjustable diagrams and explanations.
Use cases
- High school students studying Earth science
- Teachers demonstrating rock-dating principles
- Learners practicing half-life calculations
- Classes reviewing relative age and unconformities
- Students identifying geological eras from fossils
Features
- Interactive half-life models with adjustable isotope and remaining parent material
- Absolute-age examples using Carbon-14, Potassium-40, and Uranium-238
- Layer and intrusion controls for determining relative age
- Unconformity toggle showing missing geological time
- Geological-era timeline with representative index fossils
- Guided missions with reset and next controls
