1. Ice Cores and Their Stories
By: Melissa Turner

2. What are ice cores?
Ice cores are cylinders of ice that are drilled out from sheets of ice.
Ice cores can be drilled almost 2 miles deep.
The creation of ice cores has been around since the 1950s.
Most ice cores are from Antartica or Greenland.

3. What are ice cores used for?
Ice cores can be used to tell the air chemistry of another year/time.
Scientists can measure the exact amount of certain gases, such as carbon dioxide and methane that were in the atmosphere at a certain time.
Ice cores are used to study climate change in general and its past and current effects on the air and environment.

4. How do ice cores work?
Ice cores collect air bubbles inside of them which hold the information about the atmosphere during certain dates.
Snow accumulates and creates a high plateaux, there is a very slow ice flow inside of these plateaux's which keeps the ice preserved and the information still there.

5. Information gathered from ice cores?
The carbon dioxide levels in the atmosphere have increased by 40% since the industrial revolution.
The increase of fossil fuel usage and deforestation has increased the carbon dioxide levels in the atmosphere by a great amount.
