S：横波。（2）无论纵波还是横波在经过a 界面时，速度都明显加快，a 为_界面，其以上部分 A为_;横波经过 b 界面时消失，纵波速度突然减缓，b 为_界面，其以下部分C为_，其以上部分B为_。8.读图，地球的外部圈层示意图，回答：（1）填图：在图中填出地球的四大圈层。A.岩石圈 B.水圈 C.大气圈 D.生物圈（2）从图中可以看出，四大圈层尽管组成物质、分布空间不同，但他们都是以_为共同球心的圈层。20XX 年 12 月 26 日印度洋地震发生在_圈，由此引发的海啸主要发生在 _圈，流行性疾病主要在_圈传播。1 B 点拨：整体上把握地球的圈层结构。2 C 点拨：此题考查了有关地球内部圈层的划分依据。地球内部的知识，目前主要通过对地震波的研究来获得。A B 只能研究地壳的一部分。3AC点拨：此题考查了有关地震波的知识，地震波分为纵波和横波，纵波的传播速度快，能通过固态、液态和气态三态物质，而横波的传播速度慢，只能通过固态的物质。4 B 点拨：此题考查了不连续界面的位置，莫霍界面是地壳和地幔的界线，古登堡界面是地幔和地核的界线。5BC点拨：此题考查了有关岩石圈的知识。岩石圈是由岩石构成的，它包括地壳和上地幔顶部（软流层以上部分）。它和地球的外部圈层关系密切。6 A 点拨：地球的外部圈层包括大气圈、生物圈、水圈等，这些圈层相互联系、相互制约、形成人类赖以生存和发展的自然环境。7点拨：此题考查了地震波传播速度与地球内部圈层划分的关系。从图中可以看出：虚线表示地震波传播速度慢，应该是横波；实线代表纵波。从深度上和内部圈层的划分的图上信息可以看出：a 是莫霍界面，A是地壳，b 是古登堡界面，C 是地核，B为地幔。【答案】（1）图略，左侧虚线处填S，右侧实线处填P。（2）a 是莫霍界面，A是地壳，b是古登堡界面，C 是地核，B为地幔。8点拨：联系实际，考查学生对四大圈层的理解及读图、填图能力。图 1-17 地球的外部圈层示意图文档编码:CV2X10T3J1L5 HG10B1V2K3C2 ZO2A7G4H1S6文档编码:CV2X10T3J1L5 HG10B1V2K3C2
