Olympic cross-country skiing is many people racing to see who can get to the finish line faster by cross-country skiing, or skiing on flat land.

No, nordic skiing is same as cross-country skiing.

No cross-country skiing and skiing are two completely different things. They require different equipment. There are "slope" skis which most people are used to that attach to your foot and boot completely. The cross country skis have your heel loose to make it easier to propel yourself forward. Skiing is done on a slope or mountain and cross country isn't necessarily on a hill. They go across all sorts of terrain.

Cross country skiing is like cross country running, except on skis.

The skis used for cross country skiing are long and thin. Your leather ankle boots are attached only to the toe of the binding. You use poles to push off, and then throw your feet forward to continue the motion.

Cross country skiing is easy to learn, and only takes practice. There are many good skiing trail in the rocky mountains of Alberta.
