Along a special line of latitude, known as the 30th parallel north, lie numerous sites of ancient civilisations and impressive natural features. Ancient civilisations appeared on the parallel, includingBabylon, with its famous tower; Egypt, with its pyramids; China, with its Sanxingdui culture, etc. These civilisations appeared at a similar time, and all developed advanced bronze-making techniques. Were they part of a single super-civilisation, as some think? It's argued that the 30th parallel north is a line of great natural energy, with frequent earthquakes and volcanic eruptions. This creates amazing natural features, including Mount Qomolangma, the Dead Sea, and rivers, such as the Nile, theMississippi and the Yangtze. Lacking any concrete evidence, some even claim it was supernatural powers! Scientists, however, dispute these theories. It's more likely, they argue, that civilisations arose on the 30th parallel north because the climate there is generally warm and wet. Major tectonic plates meet at this latitude, causing earthquakes, which helped form the Himalayas. The rest, they say, is either coincidence or fantasy. 1. Why is the 30th parallel north mysterious? 2. What are some unusual explanations for it? 3. What are some possible scientific explanations?
