The opposite of a downward slope is an upward slope. An upward slope is a gradually rising surface or incline. It is the opposite of a downward slope, which indicates a decline. In other words, while a downward slope points in a direction of decrease or fall, an upward slope indicates a direction of the increase, growth or rise. Upward slopes are often found in mountains, hills, and on several roads. In contrast, a downward slope may be found on a regular slope or hill, incline, slide, or any surface that declines in height or steepness. Therefore, although the term "downward slope" often has a negative connotation, the term "upward slope" usually carries a positive connotation.
