Question

Dendrochronology involves dating of historic and geologic events through the study of: a.growth layers in shells. b.oxygen isotope profiles in glacial ice. c.remnant magnetism in iron-rich minerals. d.annual growth rings in trees.

Answer 1

D. Annual growth ring in trees.

Explanation: Dendrochronology is the study of the growth of tree rings. In each growth season, trees create a new ring that reflect the weather condition of that growth season. When hundreds of tree rings are put together, it tells us more about the environmental condition of the time in a specific year of the growth of the tree and the age of the tree at felling.
