Explanation:

Friction is a force that opposes the relative motion between two surfaces in contact. Sliding a book across a desk involves contact between the book and the desk surfaces, creating friction. Tires gripping the pavement also involve friction as it helps in movement and stability. A deep canyon with a river is a geographical feature (not related to friction in the context of the force between two surfaces in relative motion). Inflating a balloon is about air pressure (not friction).

Answer:

• sliding a book across a desk
• tires gripping the pavement of a road
