地壳中的沉积岩随着层状物质的聚集以及上层物质的压力使下层物质变为岩石而硬化。某一特定沉积岩层中含有异常数量的钇元素被认为是6000万年前一陨石撞击地球的有力证据。与地壳相比,陨石中富含钇元素。地质学家创立的理论认为,当陨石与地球相撞时,会升起巨大的富钇灰尘云。他们认为那些灰尘将最终落到地球上,并与其他的物质相混,当新层在上面沉积时,就形成了富含钇的岩石层。 下述哪一点,如果正确的话,能反对短文中所声称的富含钇的岩石层是陨石撞击地球的证据
A. 短文中所描述的巨大的灰尘云将会阻碍太阳光的传播,从而使地球的温度降低。
B. 一层沉积岩的硬化要花上几千万年的时间。
C. 不管沉积岩层中是否含有钇元素,它们都被用来确定史前时代事件发生的日期。
D. 6000万年前,地球上发生了非常剧烈的火山爆发,这些火山喷发物形成了巨大的钇灰尘云。
E. 大约在钇沉积的同时,许多种类的动物灭绝了。所以一些科学家提出了庞大恐龙的灭绝起因于陨石与地球相撞的理论。
