Final answer:
Unattended breaks in paved surfaces can lead to hazardous buckling in hot weather and worsened damage in cold due to thermal expansion and contraction. Other materials, biological structures, and the environment are also affected by these temperature-induced stresses.
Step-by-step explanation:
When breaks in paved surfaces are left unattended, a variety of issues can arise due to the thermal expansion and contraction that materials undergo as temperatures change. In hot weather, roadways without sufficient expansion joints can buckle, creating hazards for vehicles.
In colder temperatures, materials may contract and exacerbate existing cracks, leading to further damage. This is not exclusive to roadways; materials across various industries and infrastructures, including power lines, plaster walls, and metal objects, can suffer from thermal stress when not properly managed. For example, heavy rust can afflict metal when exposed to continuous moisture and salt spray, causing surface breakdown and cracking, as observed on the links of a chain near the Golden Gate Bridge.
Biological and environmental impacts are also significant. Food quality can be compromised when the cellular structure of frozen items is damaged due to frequent thawing and freezing. Moreover, a notable part of the sea level rise due to global warming is attributed to the thermal expansion of seawater. Therefore, it is vital to address breaks in pavements and other structural damages promptly to maintain the integrity of safety of our infrastructure, environment, and food supply.
