AThe soil type it once grew in
BThe height it reached each season
CThe climatic conditions each season
DThe species of its nearest neighbour
Answer & Solution
Correct answer: C. The climatic conditions each season
1. Each year of growth lays down one ring, so counting rings gives the age of the tree.
2. The nature of the rings, such as their size and cell wall thickness, records the prevailing climatic conditions during each season.
3. So climate is the extra information the rings carry.
4. Soil type, neighbouring species and yearly height are not read off the rings.
