Scientist drill into ice and remove ice cores for study. Scientist analynze air trapped in the ice to learn how the atmosphere has changed. Scientists can develop an accurate history of overall weather patterns over time.

What can scientists learn from studying ice cores?
Scientists use ice core samples as a way to determine what kind was in the atmosphere at different times in history. They melt the ice core under a vacuum hood to retrieve any gases in the ice. They then take the water and run it through different instruments to determine what type of pollution, dust, ash, radiation, and metals were trapped in the ice. This helps determine what the weather was like at different points in time.
What does we are all stardust mean?
It means that everything was once part of a star. A very very very long time ago.... a massive star died (went supernova) and all the material left over from that supernova started being pulled together by gravity, starting nuclear fusion, and the Sun was born. From the leftover "star dust" the planets began forming and one of those was Earth.
What two metals are found in large amounts in the inner core?

What way scientist can learn about the past is to study?
Scientists can learn about the past by studying various sources such as fossils, ice cores, sediment layers, and historical documents. By analyzing these sources, scientists can piece together information about events, climates, and life forms that existed in the past. These studies help provide insights into how the Earth and its inhabitants have changed over time.
