Both winter activities that involve sliding down a hill or slope on either skis or a snowboard. The main difference between the two activities is the equipment used and the way the user moves down the slope. Skiing involves two skis, one for each foot. Skiing techniques involve a side-to-side motion and the use of poles to propel the skier downhill. Snowboarding, however, involves the use of one board attached to the user’s feet and the user moves down the slope by controlling the board’s edges with the user’s feet. Snowboarding techniques involve an up-and-down motion and the use of the user’s hands/arms as well to control edges, as well as terrain elements such as jumps and rails.
