题目内容

【题目】根据板块运动的规律推测,以下叙述正确的有( )

(1)红海面积将扩大 (2)地中海将会消失 (3)亚欧大陆将分裂

(4)非洲大陆与南美大陆将发生碰撞

A.(2)(3)B.(3)(4)C.(1)(4)D.(1)(2)

【答案】D

【解析】

本题主要考查板块构造学说。

红海处于非洲板块和印度洋板块生长边界,也就是说两块板块距离是越来越远的,随着两块板块的漂移,红海面积就会变大,故红海海域会不断扩张;地中海位于亚欧板块与非洲板块交界处,两个板块碰撞挤压导致地中海面积减小,最终将会消失;亚洲大陆和欧洲大陆是一个大板块,板块内部相对比较稳定;非洲大陆与南美大陆之间隔着大西洋,而大西洋面积会不断扩大,因此二者不可能发生碰撞。所以(1)(2) 根据板块运动的规律推测正确。故选D
