该图为“地球圈层结构示意图”,读图回答问题。

下列有关地球圈层特点的途述,正确的有()

A.①圈层为人类主要活动环境

B.②圈层的厚度陆地较海洋大

C.③圈层横波不能穿过

D.④圈层的物质状态为固体

答案

参考答案:B

解析:

人类活动的主要环境是陆地环境,不是①所代表的平流层。地震波在地球内部传播的过程中,只是地表以下大约2900千米处的古登堡面处突然消失,在地壳和③所在的软流中是可以通过的,横波不能通过④所在的圈层,说明它是处于一种准液态状态,故选项ACD都是错误的。只有选项B的说法是正确的,②所代表是地壳,地壳的最大特点是厚度的不均一性和硅铝层的不连续分布,大陆地壳是双层结构既有硅铝层,也有硅镁层,比较厚;大洋地壳为单层结构,只有硅镁层,比较薄。故选B

考点:地球各大圈层分布状况

点评:本题不仅要求考生熟悉地球内部各大圈的名称与分布,同时还要求对各圈层所在的距地表的深度数字都比较熟悉,难度虽然不大,但识记性较强。
