Question

question 9
what is black ice?
select one:
a. dry ice.
b. a thin film of ice covering the road.
c. lake ice.
d. another name for hydroplaning.

Explanation:

Black ice is a thin, nearly transparent layer of ice that forms on road surfaces, making it hard to spot. Dry ice is solid carbon dioxide, lake ice is ice on lakes, and hydroplaning is a vehicle sliding on wet roads, so none of these match the definition of black ice.

Answer:

b. A thin film of ice covering the road.
