【解析】

试题分析:

(1)板块运动学说认为,由岩石组成的地球表面并不是一块整体,而是由亚欧板块、太平洋板块、非洲板块、美洲板块、印度洋板块和南极洲板块六大板块拼合而成。据图可知:A为亚欧板块;B为非洲板块;C为印度洋板块;D为太平洋板块;E为美洲板块;F为南极洲板块。

(2)板块运动学说认为,组成地表的各大板块处于不停的运动中。一般来说,板块的内部地壳比较稳定,板块与板块交界的地带即板块边缘地带,有的张裂拉伸,有的碰撞挤压,地壳比较活跃,容易形成火山、地震。

(3)据图可知:澳大利亚所在的板块是印度洋板块,太平洋板块是几乎全部位于海洋的板块。

(4)科学的避震方法在一定程度上可以降低人员伤亡。地震发生时,如果在室内(楼房),可选择在坚实的家具下或小跨度卫生间、厨房等处躲藏;在教室里要在教师指挥下迅速抱头、闭眼、蹲在各自的课桌下。地震一停,迅速有序撤离;无论在何处躲避,都要尽量用棉被、枕头、书包或其他软物体保护头部,发生地震时应远离建筑物、危险品,就近采取防护措施,因此躲在高大建筑附近、高架桥下是错误的,故本题选B。
