The Fertile Crescent / Agricultural Revolution The area between Saudi Arabia and Iran was just dry land.Īpparently, the land, which now lies at the bottom of the Persian Gulf, was fertile and home to highly developed human settlements. Until about 8,000 years ago, there was no Persian Gulf, and therefore no Arabian Peninsula. The year 13000 BC is significant because before then, humans would not have been able to pass through the glaciers that covered Canada, also clearly visible on the map. Humans first arrived in the Americas sometime around 13000 BC after crossing the Bering Strait between Russia and Alaska. You can see the Bering Strait land bridge in the video as it gradually submerges and disappears around 8000 BC. The land bridge between Russia and Alaska Interesting things to look out forĪfter watching the video several times, here are a few of the interesting things that caught my eye. Or skip to the bottom of this post to view it as an interactive map ( full screen version). If the video is too fast, head over to Youtube and watch the original 2-minute timelapse. To fully appreciate this one, it’s worth watching it a few times. There are so many interesting things to notice, some very subtle, all happening at the same time Watch our planet evolve, from the last ice age to 1000 years in the future Ī few weeks ago I posted another graphic by the same team at ZHAW, which showed 24 hours of global air traffic condensed into a four-second flurry of yellow dots. Timelapse of the Earth’s surface, 19000 BC – 3000 AD From 19000 BC to 3000 AD, it shows the evolution of the Earth’s surface, including sea levels, coast lines, ice cover, and vegetation. What if we had satellite imagery of the Earth going back thousands of years into the past? Or into the future?Ī team at the Zurich School of Applied Sciences has created exactly that: an animated, and quite realistic-looking, map of the earth covering 21,000 years. That’s a short time frame on the scale of planetary shifts, but the images still show some striking trends, such as the recent shrinkage of the polar ice cap. Today we have satellite images that let us see how the Earth’s surface changes from year to year.
