三种岩石

上周末去了Lulworth,上了一点地质课。英国南方的中学,多半都会组团带中学生去Lulworth了解地质。 英国学生学地理,是要到户外考察的,是要真正触摸泥土和石头的。

我在80年代上中学,上地理课的经历是很惨痛的,教地理的老师原来都不是地理系出身的,他们没有专业训练,平常只会摇头摆脑念课文,一字不漏的念,要我们一字不漏的背。这样的老师,上课之前也是没有备课的。这样的老师,还不只一个。

话说回Lulworth的地质,让我有初识的惊叹,让我有当学生的童真,让我想起,原来有很多东西,我们曾经那么努力地背过,背过后,考试过后,又忘得一干二净的。

还记得组成地球岩石圈的三种主要岩石吗?

沉积岩(水成岩)(Sedimentary Rock)

岩浆岩(火成岩)(Igneous Rock)

变质岩 ( metamorphic rock)

 在Lulworth,所有的岩石都属沉积岩(水成岩)(Sedimentary Rock) 。
