Final answer:
Hydroplaning is when the tires of a car lose contact with the road surface due to water, reducing control and making it harder to steer, brake, and accelerate.
Step-by-step explanation:
When a heavy rain occurs, the tires of a car can begin to ride on the water that is on top of the road pavement. This phenomenon is called hydroplaning. Hydroplaning happens when the tires lose contact with the road surface due to the presence of water. It can significantly reduce the control of the car, making it harder to steer, brake, and accelerate.
