Ice cores are essentially big ice blocks that are taken from glaciers and ice caps. They show levels of dust and atmospheric gasses trapped in the ice which show the different levels at different stages in the earth's cycle of climate change.
There are many different 'sites' where they take these samples from including Greenland and Antarctica (to name a select few).

What are ice cores for climate analysis drawn from?
The cores are drilled from the ice itself - ice sheets in Antarctica and Greenland.
How does a ice cores change?
You can see it!
Where do scientists obtain ice cores from?
Glaciers and/or the Arctic/Antarctic ice caps.
What are Ice Cores used for?
to determent past climates
Why do scientist use ice cores?
to find out what the composition of the atmosphere was
How can ice cores be used to be determine past climates?
pudding
Why are ice cores good indicators of past climate?
Ice cores contain tiny bubbles that contain a sample of the atmosphere from that time period. By studying the ice bubbles, it is possible to reconstruct the composition of the atmosphere at that time and thus the climate.
Why do ice cores taken from polar regions contain much older information about Earth's climate than ice cores taken from mountaintops?
Because the snow is very compressed in the polar regions
Differences between ice cores and tree rings?
Ice Cores shows the layers of snow it tell about atmosphere... The Tree show it age in tree rings and shows dryness mostly about the weather...
Can you use Ice Core in a sentence?
Ice cores are very brittle due to the quick change in pressure.
How do tree rings and ice cores help scientist understand how Earth has changed over time?
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.
Which part of earths history is shown by analysis of ice cores?
Changes in climate
