Final answer:
Driving on gravel provides less traction than when driving on concrete.
Step-by-step explanation:
Driving on gravel provides less traction than when driving on concrete. Gravel is a loose surface that does not provide as much grip as the smooth surface of concrete. When driving on gravel, the tires can easily slip and slide, resulting in less control and traction compared to driving on concrete. For example, when driving on a gravel road, the tires may skid or spin, especially during braking or acceleration. This is because the gravel particles are not compacted and the tires cannot make good contact with the road surface. On the other hand, when driving on concrete, the tires have better traction due to the smoother and more stable surface, providing more grip and control.
