Summarize this article for a 10 year old
Roller skiing is an off-snow equivalent to cross-country skiing. Roller skis have wheels on their ends and are used on a hard surface, to emulate cross-country skiing.[1][2] The skiing techniques used are very similar to techniques used in cross-country skiing on snow.
First created as a summer training exercise, roller skiing grew into a competitive sport in its own right. Annual championships are held in various locations around the world.[3] Most, if not all, national cross-country ski teams around the world roller ski during the off-season for specific physical training simulating winter skiing. In Norway, separate roller ski facilities have been constructed to allow exercise off public roads.[4]
