The term 'IT HAS RINGS' can be solved by the word 'TREE', which is a four-letter word. Trees are a type of plant that have been around for millions of years and are found in many different climates and habitats. They are characterized by their tall trunks, branches, and leaves, and they often have rings that can be seen when the trunk is cut open. These rings indicate the age of the tree and can be used to study the history of the environment.
