问题 单项选择题 案例分析题

如图示意一天内不同时刻沿水泥混凝土面层(指路面最上层)深度的温度变化状况,读图回答下列各题。

分析图示信息所得出的结论中,可以确定的是()

A.水泥混凝土比热容小,不适宜作路面建设材料

B.表层剧烈的温度变化会导致路面开裂,铺设水泥混凝土路面应做防裂处理

C.铺设水泥混凝土路面是缓解城市热岛效应的有效方法

D.一天中10:00~14:00水泥混凝土面层表面增温最快,应进行洒水降温

答案

参考答案:B

解析:

结合上题分析可知:水泥路面的表层气温变化大于路面深处,故不同程度的温度变化导致的不容程度的热胀冷缩会使路面开裂,所以本题B正确。

考点:本题主要考查大气受热过程。
