Question

what statement is accurate based on the study of tree rings?
trees near the arctic will have thicker rings than those near the equator.
trees with a pattern of thin rings indicate a wet, warm climate.
size and density of tree rings can give information on past climates.
the number of rings indicate how much fruit the tree can bear.

Explanation:

Tree - ring analysis (dendrochronology) is used to study past climates. Thicker rings usually form in favorable growing conditions (warm and wet), while thinner rings are from less - favorable conditions. The size and density of tree rings can be correlated with historical climate data. Trees near the arctic generally have thinner rings due to harsher conditions. Thin rings indicate a less favorable climate, not a wet and warm one. The number of rings indicates the age of the tree, not fruit - bearing capacity.

Answer:

Size and density of tree rings can give information on past climates.
