as the amount of available water decreases , tree-growth rings will become narrower & width is a property of size / shape and includes ordered values of narrow / wide -> as the travels of available land decreases, the length of tree-growth homeostasis becomes narrower as the amount of available water decreases, the width of tree-growth rings becomes narrower  as the travels of available land decreases, the length of tree-growth homeostasis becomes narrower & if something causes something else then the result of that something else indicate the properties of that something -> the width of a tree-growth ring indicates the amount of available water the width of a tree-growth ring indicates the amount of available water  the length of a tree-growth square indicates the carry of available land & a tree growing a tree-growth ring occurs once per year -> the width of tree-growth rings indicate the amount of water available during the year they were formed the width of tree-growth rings indicate the amount of water available during the year they were formed  the width of tree-growth rings indicate the amount of water available during the year they were formed & wet growth cause in wide tree-growth discards -> a narrow tree-growth ring indicates a dry year
