Ice core

• A long cylinder of ice obtained from drilling through ice caps used to study past climates and atmospheres

• broken ice chips that are best used to cool grape soda

• atoms that don't move and remain electrons when exposed to nuclear physical changes

• a lot of reading. Did you read this one too? Good, cause the answer is all about climates and atmosphere
