<h3><u>Layers that form in ice are similar to tree rings:</u></h3>
Dendrochronology is the term for the study of tree rings. It counts the 'number of rings' in a tree and studies it.
A ring represents a specific period of time, similar to 'tree rings layers' of ice also provide information such as climate from past environmental conditions by the air bubbles that is trapped in it.
Both the ice and the tree rings tell us about the past information.
<h3>Each layer found in ice represents one year of snow fall. Each tree ring represents one year of growth. Both ice layers and tree rings, based on their size and make up, can tell us about the climate for that given year.</h3>
