Scars present in tree rings indicate

• fire

• disease

• insect damage

• all of the above

People count tree rings to find out

• what kind of tree it is.

• the kind of soil the tree needs.

• the age of the tree.

• how long the tree will live.

How do scientists collect evidence about climate?  

• using remote sensing from space with satellites
• by ground-based measurements of surface temperatures, carbon dioxide concentration and sea level
• by collecting “proxy data” from tree rings, ice cores, and historical records
• all of the above
