Tar is a thick, dark, sticky substance that is often used in road construction and repair. It is a result of heating coal or petroleum and is used to bind materials together, such as in asphalt for paving roads. Tar is also used in roofing and waterproofing. It has a strong, unpleasant odor and can be harmful if not handled carefully.
