to determent past climates
What are two major methods that climatologists use to find out the earths past climate history?
Studying tree rings, Dendrochronology is one way.Studying ice cores is another, in particular looking at the ratio of 16O to 18O. This ratio (in precipitated water) is sensitive to the ambient temperature.
How can ice cores be used to be determine past climates?
pudding
Why do scientist use ice cores?
to find out what the composition of the atmosphere was
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?
