Niagara Falls has been a famous honeymoon spot for over a hundred years: some honeymooners have been more faithful to it than to each other.
一百多年来,尼亚加拉大瀑布一直是著名的蜜月旅行圣地:许多新婚夫妇对它情有独钟,甚至胜过对配偶的忠诚度。
When The Falls Formed
瀑布何时形成
Since the falls were formed during the late Pleistocene period, about twelve thousand years ago, they have been subject to the force of erosion.
大瀑布形成于更新世时期晚期,距今一万两千多年,此后大瀑布一直遭受着外力侵蚀。
shicha121.jpgAs they erode, the falls are moving upstream, so they will one day disappear into Lake Erie.
随着不断被侵蚀,大瀑布也在逐渐向上游移动,因此,终有一天,大瀑布将消失在伊利湖。
Like all waterfalls, Niagara erodes because water wears away the softer rock at the base of the cliff, where a turbulent pool forms below the waterfall.
像所有的瀑布一样,尼亚加拉大瀑布遭受侵蚀是因为水流不断地冲刷悬崖底部硬度较低的石头,而瀑布下方形成湍流池。
Because erosion affects the base of the cliff, the old cliff face will collapse and the new edge will be slightly upstream.
因为侵蚀会影响悬崖底部,陈旧悬崖因侵蚀坍塌,新的悬崖形成并将逐渐往上游移动。
