When ice freezes it can freeze gas and other material inside of it and some ice may have been there from thousands of years ago and scientists may want to find out how much carbon dioxide was in the atmosphere then etc.

Where do scientists obtain ice cores from?
Glaciers and/or the Arctic/Antarctic ice caps.
What have scientists learned from studying ice cores?
hi mazz stop stairin at the window
What are ice cores for climate analysis drawn from?
The cores are drilled from the ice itself - ice sheets in Antarctica and Greenland.
Why do scientist use ice cores?
to find out what the composition of the atmosphere was
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...
Where do scientists obtain ice cores from?

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.
In antarctica scientists study environmental changes that occurred over tousands of years by taking.?
Generally, the data source you're thinking of is ice cores.
Has anyone ever tried to bring back ice from antarctica?
Ice cores taken by scientists to study the health of planet earth are returned under refrigeration to scientific laboratories on other continents.

How do scientists learn about the climate in Antarctica thousands of years ago?
Ice cores are useful for scientists who want to learn about the climate in Antarctica thousands of years ago.
What are ice cores for climate analysis drawn from?
The cores are drilled from the ice itself - ice sheets in Antarctica and Greenland.
Scientists are able to accurately determine the atmospheric composition from thousands to hundreds of thousands of years ago by what means?
analysing cores of ice and rock formations
What do scientists call the study of ice and its impact on the environment?
Hmm, I Really Wouldn't Know.
Why are scientists drilling into the Antarctic ice?
Ice cores drilled in Antarctica -- and in many other ice sheets throughout the world -- can be analyzed in the lab for the atmospheric contents present during the period when the ice froze. These data give scientists treasure troves of data that have to do with climate and climate change over tens of thousands of years of Earth's atmospheric history.
How does a ice cores change?
You can see it!
Why do scientists come to antarctica?
Scientists work and live in Antarctica temporarily, to study the health of planet earth.
