Final answer:
It is true that leaves can remain wet and slick long after rain, posing slippery conditions similar to ice for drivers. Increased friction is also favorable in sports like basketball, where proper footwear enhances grip. While a light rain makes roads slippery due to oil and gasoline, heavy rain can wash these substances away, improving traction.
Step-by-step explanation:
The true or false statement: 'Long after rain, leaves on the road may still be wet and slick as ice,' is true. Wet leaves on the road can act similarly to ice, causing a reduction in traction for tires, which poses a hazard to drivers. This is because leaves retain moisture, and when combined with road oils, they create a slippery surface that is very slick and similar to driving on ice. It is always advisable to exercise caution when driving in conditions where wet leaves are present on the road surface.
Another example where more friction is desirable besides when driving over icy roads with winter tires, is when playing basketball. Players prefer sneakers with rubber soles that grip the court surface to prevent slipping, enhancing performance and safety.
Oil and gasoline leaks on road surfaces can make driving conditions dangerous, especially during a light rain, as these substances create a slippery mixture lowering vehicle control. A heavy rain, however, can dilute and wash away these substances, potentially improving traction compared to lightly wet conditions.
