伊莉絲‧卡茲: 為什麼一天會有兩次潮汐？

為什麼一天會有兩次潮汐？

在十七世紀，牛頓首次用引力的角度來解釋潮汐。他的發現沒錯，潮汐變化的編排來自天體的運動，而地球的潮汐主要由月球所帶動。但這種關係的本質其實相當微妙。伊莉絲‧卡茲透過這支影片來解釋太陽和月球如何影響潮汐。

Earth experiences two high tides every day, the result of a delicate dance between the Moon’s gravity and the planet’s rotation. The Moon pulls ocean water toward it, creating a bulge, while the Earth’s motion forms a second bulge on the opposite side. Ancient armies like Alexander the Great’s once faced tidal phenomena such as a tidal bore along the Indus River, centuries before Newton explained the science. The Sun’s gravity, local geography, and even the movement of distant planets all weave together to produce tides that shape our world and others.
