Final answer:
The dating method principle for potassium-argon, uranium series, and radiocarbon dating is radioactive decay. The dating method principle for geomagnetism is aligning particles to the Earth's poles. The dating method principles for electron spin resonance and thermoluminescence are accumulation of energy or particles over time.
Step-by-step explanation:
1. Radioactive decay - potassium-argon, uranium series, radiocarbon dating
2. Aligning particles to the Earth's poles - geomagnetism
3. Accumulation of energy or particles over time - electron spin resonance, thermoluminescence
