Final answer:
Snow skis were first made from the bones of large animals and used primarily for traveling on flat ground. It wasn't until advancements in technology that skiing became a popular sport.
Step-by-step explanation:
Snow skis were first used in northern Europe and Asia thousands of years ago.
They were likely fashioned from the bones of large animals and strapped with strips of leather to the boots of skiers.
These early skis were primarily used for traveling on flat ground.
The loose bindings made them unsuitable for downhill movement.
It wasn't until the development of better skis, more secure fastening methods, and ski lifts that skiing became a recreational and competitive sport.
