What are ice cores for climate analysis drawn from?
The cores are drilled from the ice itself - ice sheets in Antarctica and Greenland.
Where do scientists obtain ice cores from?
Glaciers and/or the Arctic/Antarctic ice caps.
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...
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.

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.

The cores are drilled from the ice itself - ice sheets in Antarctica and Greenland.
Why is jack hall taking ice core samples from antarctica?
Jack Hall was studying the greenhouse gases in ice cores from Antarctica because runaway greenhouse gases are causing global warming.
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.
How does a ice cores change?
You can see it!
What other clues did scientist use to learn about ice man life?
He use Weapon with a stone
The Antarctic ice cap was found to be an abdudant source of?
The Antarctic ice sheet contains about 70% of the earth's fresh water and about 90% of the earth's store of ice. As well, the ice sheet can be drilled. Studying cores reveals a history of planet earth's environment going back millions of years.
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
