The term is hydroplaning.
It is called hydroplaning. Tires are designed to shed water from the grooves. When they can't shed enough water, the water will build up in front of the tire and eventually lift it completely off of the road. Once that happens, and there is no more friction from contact with the road, the tires will slide across the sheet of water like skis until the car either runs into something, or slows down enough that the tires regain contact with the road.
When a vehicle hydroplanes, the friction the tires are against is something other than the roadway - typically, it's a layer of water between the tires and the roadway. As the water has much less resistance and friction than asphalt, the tires spin much more freely.
Runoff is best described as the movement of excess water over land surfaces, often resulting from precipitation. It can lead to erosion, flooding, and transport of pollutants and sediments into water bodies.
Because there is less friction between the hull and the water than there is between the road surface and the tires.
Water, ice, snow, sand.
Because the water on the ground acts like an oil diminishing the grip. And when the ground is wet the water molecules resides between the ground and tires so, the tire is not in total contact with the ground.
Runoff refers to the flow of water over the surface of the land after precipitation, which can lead to erosion. Sheet erosion is the process where a thin layer of soil is removed uniformly from a large area by the action of water flowing over it. In essence, runoff can cause sheet erosion as the water moves across the land.
The water creates a layer between your tires and the road so your tires don't grip the road, they lose traction.
Salt water can be described as water that has salt in it.
Water is way too heavy to put in tires, plus in the winter it will settle and freeze so your tires will be off balance. Also about the winter part, if you completely filled your tires with water and let the water freeze, the tires would explode, since water expands when it freezes.
A layer of water formed to cause the tires to hydroplane, causing no traction on the road surface.
