【题目】下列说法正确的是( )

A. 红海正在不断缩小,几千万年后将会消失

B. 地中海在不断扩张,几千万年后将会成为新海洋

C. 由于印度洋板块不断挤压亚欧板块,因而珠穆朗玛峰还在不断升高

D. 地球的“伤疤”—东非大裂谷在不断隆起,这条“伤疤”将会从地球上消失

【答案】C

【解析】

根据地球表层不是整体一块,而是由板块拼合而成。全球大致划分为六大板块,各大板块处于不断地运动中。一般来说,板块内部地壳比较稳定,板块交界地带,地壳比较活跃,多火山和地震。板块和板块之间运动频繁,但力的方向不同。板块发生张裂运动时,其运动方向相反,板块之间的距离不断扩张,形成海洋或裂谷;板块发生挤压运动时,其方向是相向运动,板块之间的距离缩小,地表还会不断隆起,形成山脉,进行分析解答。

红海位于非洲板块与印度洋板块的张裂拉伸处,其面积逐渐扩大,故A错误;

地中海位于欧亚板块与非洲板块的碰撞挤压处,其面积逐渐缩小,几千万年后将会消失,故B错误;

珠穆朗玛峰位于印度洋板块与欧亚板块的碰撞挤压处,其海拔逐渐升高,故C正确;

东非大裂谷位于板块的张裂拉伸处,不会在地球上消失,故D错误。

故选:C
