Final answer:
On and off ramps/bridges get icy quickly due to temperature change and moisture. Applying salt or de-icing chemicals and using proper drainage systems can help prevent ice formation.
Step-by-step explanation:
In the context of physics, the quick formation of ice on on and off ramps/bridges can be explained by the change in temperature and the presence of moisture. When the temperature drops below freezing, any moisture on the surface of the ramps/bridges will freeze, creating ice.
This happens quickly on ramps/bridges due to their elevated position, which allows cold air to circulate underneath and around them, cooling the surface rapidly. Additionally, cars driving on the ramps/bridges can contribute to the formation of ice by spreading moisture from their tires onto the surface.
To prevent icy conditions, measures can be taken such as applying salt or other de-icing chemicals, as well as using proper drainage systems to remove excess moisture. These methods help to lower the freezing point of water and prevent ice from forming.
