NASA Reveals How The Earth Would Look If The Oceans Were Drained
6Then comes more land
According to scientists, the continental shelves include some of the land bridges that were used by early man and animals to migrate over to other continents. With time those land bridges got eroded by water before being completely submerged. There was a time when people could walk from one continent to another.
7How did these landmasses get submerged?
According to scientists who have been researching the Earth’s landmass for years they have concluded that there were land bridges that our ancestors could use to walk from continental Europe to the UK and also from Siberia to Alaska. These are not visible anymore because the Ice Age destroyed them. To be more accurate the thaw after the Ice Age destroyed them.
8What happened during the ice age?
When the ice age took place a lot of Earth’s water was frozen still due to which there was more landmass covering the earth’s surface. During this time the percent of Earth covered with the land was more than we know today. This is when these land bridges were used. But, unfortunately when the ice melted these landmasses got covered once more.
9The video shows a world that once was
The video was meant to show how the world once looked before it was covered with water and how it looks today. The video slowly progresses from what the world looks like today and by slowly draining the water meter by meter we end up seeing what the world would look like if all the water was to be drained from the planet.
10Do we need all this water?
While many will argue the world as we know it would’ve even existed if it were covered by only 50% water instead of the 71% it is today. There are some who say this is why there is life on Earth and that this is the balance that we need. The land and water are two different biomes that work together to keep things in balance.
