6、 formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles(气泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate. By examining ice, we know carbon dioxide in the atmosphere is higher now than in the last
