Detailed explanation-1: -Drought, disease, temperatures that are too hot or too cold and shading or crowding by other trees can slow down tree growth, leaving narrow rings. Studying rings from many trees across the landscape can help scientists understand how the climate may be changing and affecting forest ecosystems over time.
Detailed explanation-2: -The cambium cells on the outside become part of the tree’s phloem, a band of inner bark through which the tree’s food supply moves. The cambium cells on the inside become the xylem, a system of tiny tubelike cells that carry the tree’s water supply. These xylem layers give us the annual rings.
Detailed explanation-3: -Answer. Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings.
