Which is one way that analyzing ice benefits scientists who study ancient climates? Scientists can analyze frozen volcanic dust to help predict eruptions.
Scientists can study the layers of ice cores to gather information about past atmospheric composition.
Scientists can use pollen grains in ice to make inferences about the climate area.
Scientists can study tree rings in ice to learn more about past climates.

Ice cores provide a unique contribution to our view of past climate because the bubbles within the ice capture the gas concentration of our well-mixed atmosphere while the ice itself records other properties. Scientists study the gas composition of the bubbles in the ice by crushing a sample of the core in a vacuum.
