Question

what absolute - age dating technique uses information about seasonal and environmental conditions?
dendrochronology
radiometric dating
superposition
radiocarbon dating

Explanation:

Dendrochronology is the study of tree rings. Tree rings are formed seasonally (a new ring each year). The width and characteristics of these rings are influenced by environmental conditions (such as rainfall, temperature) during that growing season. Radiometric dating (including radiocarbon dating) is based on the decay of radioactive isotopes. Superposition is a principle in geology about the order of rock layers (not related to seasonal/environmental info for dating in the way the question asks).

Answer:

dendrochronology
