The two correct answers that scientists study to determine air temperature at the time it was formed are:
1. **Ice formed thousands of years ago**
2. **Chemical isotopes in foraminifera shells**
Tree rings and fossilized pollen can provide information about past climates and environments, but the other two directly relate to temperature reconstruction over geological timescales.
