2024年四川省成都市地理高考试题与参考答案

2024年四川省成都市地理高考试题与参考答案一、单项选择题(本大题有16小题,每小题3分,共48分)1、某旅游团从成都出发,沿川藏公路进入西藏,沿途欣赏到了美丽的自然风光,也感受到了独特的藏族文化。
该旅游团沿途依次看到的自然景观是( )A. 森林、草原、荒漠B. 荒漠、草原、森林C. 草原、荒漠、森林D. 森林、荒漠、草原答案:A解析:本题考察的是对川藏公路沿线自然景观的理解。
选项A,川藏公路沿线,从成都出发,首先会经过亚热带季风气候区,这里降水较多,适合森林的生长,因此首先看到的是森林景观;随着海拔的升高,气候逐渐变得干旱,降水减少,植被由森林逐渐变为草原;当到达高原地区时,气候更加干旱,植被稀疏,逐渐变为荒漠景观。
因此,A选项正确。
选项B,川藏公路沿线并非先经过荒漠再经过草原,这与实际情况不符,故B错误。
选项C,川藏公路沿线并非先经过草原再经过荒漠,而是先森林后草原再荒漠,故C错误。
选项D,川藏公路沿线并非先经过森林再经过荒漠,荒漠景观应出现在草原景观之后,故D错误。
2、2013年4月20日,四川省雅安市芦山县发生了7.0级地震。
地震发生时,成都市民感到房屋摇晃,但持续时间很短。
关于这次地震,下列说法正确的是 ( )A. 成都市民感到的摇晃是由纵波造成的B. 芦山县地震释放的能量来源于地球内部的核裂变C. 芦山县地震发生时,P波和S波传播方向相反D. 芦山县地震的震源位于地壳中答案:D解析:本题考察的是地震波的特点、地震能量的来源以及地震的震源位置。
选项A,成都市民感到的摇晃主要是由横波(S波)造成的,因为横波传播速度较慢,但振幅较大,能引起地面的上下和左右晃动,故A错误。
选项B,芦山县地震释放的能量主要来源于地球内部的放射性元素衰变,而非核裂变,故B错误。
选项C,在地震发生时,无论是P波(纵波)还是S波(横波),它们的传播方向都是相同的,都是从震源向四周传播,故C错误。
选项D,芦山县地震的震源位于地壳中,因为地壳是地球固体地表构造的最外圈层,整个地壳平均厚度约17千米,其中大陆地壳厚度较大,平均约为39-41千米,因此地震的震源大多位于地壳中,故D正确。
