Final answer:
Surfaces that provide poor traction include icy roads, which have a low friction coefficient. More friction is desirable when climbing a steep slope to maintain a better grip and avoid slipping.
Step-by-step explanation:
Surfaces that provide poor traction are those that have low friction coefficients. For example, icy roads have a low friction coefficient due to the ice layer covering the surface, making it difficult for tires to grip the road. Another example where more friction is desirable is when a person is climbing a steep slope. In this case, increased friction between the person's shoes and the ground helps them to maintain a better grip and avoid slipping.
