来到瑞芳镇水湳洞的「黄金瀑布」，这座位在公路旁背倚无耳茶壶山的层叠瀑布，因含有丰富的黄铁矿与硫砷铜矿，让地表呈金黄色，也是形成阴阳海的主要水源，当奔腾的瀑水流泄而下时就像是一座堆满金矿的瀑布般，耀眼动人，一幕清澈的水帘直冲金黄色的地表让人一时兴起玩水念头，不过由於这里的水质含有大量重金属物质，为了自身安全，还是三思而后行，黄金瀑布位於本山六坑口下方的自强桥畔及长仁矿区，因为早期在上游采铜矿，山泉水与雨水渗入，矿砂沉积溪床，又有菌类附着滋生、地势落差较大所以形成金黄色的瀑布奇观，黄金瀑布是金瓜石当地很有特色的一个景点，平时也很容易遇到来此地拍摄婚纱的新人。

As the result of his work, he could announce the Law of Seriation of Rare Earths: all salts of rare earths fall in the same order of solubility, except the ethyl sulfates and the nitrates.

Using the latest satellite imagery and 3D graphic animation, trade-winds, tornadoes, lightning, monsoon, and hurricanes are examined in detail. From the aurora borealis to the bizarre downpouring of fish and frogs, we learn that the earths atmosphere is a delicate and ever-changing environment. Finally we delve into the past to discover how earths volcanic origins helped create weather as we know it.

信风、龙卷风、闪电、季风与飓风被用最新的卫星影像与三维动画图像演示详尽地分析研究；从北极光到鱼蛙稀奇古怪的倾盆大雨，我们懂得了地球的大气是个微妙多变的环境……最后，我们将深入历史，去探索火山这一源头是如何造出我们所知的天气的。
