题目分析:(1)地球表层是由六个大板块拼合而成,其中:A是亚欧板块,C印度洋板块, E美洲板块,(2) 各大板块处于不断运动之中。一般来说,板块内部地壳比较稳定,板块与板

块交界地带,地壳比较活跃,多火山、地震。(3)我国是一个多地震的国家,因为我国位处在环太平火山地震带和地中海-喜马拉雅火山地震带之间。(4)从图2可以看出,日本是一个多火山地震的国家,主要是因为它位于亚欧板块和太平洋板块的交界处。

点评:本题还可以考查地壳的板块结构:(1)六大板块:名称、位置、范围、背图(2)大部分板块与大陆、大洲、大洋的范围一致。注意:亚欧大陆的阿拉伯半岛、印度半岛不在亚洲板块上而在印度洋板块上;亚欧大陆的东北角不在亚欧大陆而在美洲板块上,只有太平洋板块为唯一的大洋板块。应用:①红海不断扩大:印度洋板块与非洲板块的张裂运动;②地中海在不断缩小:亚欧板块与非洲板块碰撞运动;③喜马拉雅山的形成、珠穆朗玛峰的不断升高:亚欧板块与印度洋板块碰撞运动;④日本、台湾多地震:亚欧板块与太平洋板块的碰撞运动;⑤太平洋不断缩小:太平洋板块的周边板块向其作碰撞挤压运动。
