【题目】根据板块构造学说,下列说法正确的是( )
A. 海洋和陆地的分布是固定不动的 B. 地球表面由整体的一个板块构成
C. 板块的交界处地壳比较稳定 D. 世界火山、地震主要分布在板块的交界地带
【答案】D
【解析】
试题
地球表面形态处于永不停息的运动与变化之中.地质学家经过长期的研究,提出了板块构造学说,认为全球由六大板块组成,一般来说板块内部比较稳定,板块与板块交界地带,地壳比较活跃,多火山、地震.地球表面形态处于永不停息的运动与变化之中,海洋可以变成陆地,陆地可以变成海洋,因为海陆变迁需要漫长的时间,所以人们短期内察觉不到.实际上海洋和陆地的分布是不断变化的,所以A错。板块构造学说认为全球由六大板块组成,所以B错。 一般来说板块内部比较稳定,板块与板块交界地带,地壳比较活跃,多火山、地震,所以C错。 一般来说板块与板块交界地带,地壳比较活跃,多火山、地震,所以D对。

【题目】阅读下列材料回答相关问题
厉害了!我的国
(一)西成高速铁路,简称“西成高铁”,是国家八纵八横高铁网络规划中“京昆通道”的重要组成部分。高铁自西安北站引出,自北向南穿越关中平原、秦岭山脉、汉中平原、巴山山脉进入四川盆地,与成绵乐城际铁路相连,接入成都东站。西成高铁全线于2017年12月6日开通运营,西安至成都的运行时间将由普快11个小时缩短为4小时。
(二)2017年11月28日,由中国国电集团公司与神华集团有限责任公司合并重组的国家能源投资集团有限责任公司在北京正式成立。据悉,重组后的国家能源集团资产规模超过1.8万亿元,拥有33万名员工、8家科研院所、6家科技企业。拥有四个世界之最,分别是世界最大的煤炭生产公司、世界最大的火力发电生产公司、世界最大的可再生能源发电生产公司和世界最大煤制油、煤化工全司。
(三)2017年12月10日,是洋山深水港四期码头开港试生产的日子。它在上海东南部,远离陆地逾30公里,一座东海上的小岛扩张近6倍,从深渊“造”出800万平方米土地,摇身变为全球单体最大的全自动化码头!有了它,上海港的集装箱吞吐量,连续7年排名世界第一,洋山四期开港后,将助推上海港年吞吐量,突破4000万标准箱,等于美国所有港口吞吐量之和!整个码头和堆场内将不再有人,不仅岸桥不需要人驾驶,连集装箱卡车也不再需要,直接由自动运行的无人驾驶AGV小车把集装箱运到堆场,堆场的桥吊也是无人操作。原先的码头操作员全部转移到监控室,对着电脑屏幕就能完成全部作业。
(四)港珠澳大桥是中国的一座跨海大桥,是连接香港、珠海、澳门的超大型跨海通道。全长55公里,建成后将成为世界最长的跨海大桥。其中,工程量最大、技术难度最高的是长约29.6公里的桥一岛一隧集群的主体工程。主体工程“海中桥隧”长35.578公里,其中海底隧道长约6.75公里。建成后将会为G4 -京港澳高速以及G94 -珠三角环线高速的一部分。
港珠澳大桥沉管隧道是全球最长的公路沉管隧道和全球唯一的深埋沉管隧道,生产和安装技术有一系列创新,为世界海底隧道工程技术提供了独特的样本和宝贵的经验。2017年11月14日,港珠澳大桥主体工程荷栽试验完成,于2018年元旦建成通车。
(1)“西成高铁’’中的“西”指的是 。
