Earth In 200 Million Years
Δημοσιεύτηκε στις 11 Σεπ 2014
Find out about a new supercontinent
in the making, called Pangaea Ultima. Previously, there was Ur, then
Kenorland, Protopangaea, Nuna, Rodinia, Pannotia, and Pangaea. The break
up of Pangaea beginning around 100 million years ago set the stage for
the world we know, with its particular mix of continents and oceans.
Geologists
have been able to piece together the history of Earth’s continents by
looking at where and when mountain ranges formed, and by studying
magnetic signatures that link rocks found in disparate locations.
They
have found that plate motions have been accelerating. Over the last two
billion years, the rate at which continents have collided or shifted
their positions has doubled. What new patterns are emerging now in the
volcanoes and earthquakes that rattle our planet from year to year?
The
continents we know today will fragment and recombine as they have in
the past. Plants and animals will continue to evolve as they have for
hundreds of millions of years. Will mammals dominate the new
supercontinent? Or will another life form take over? Will humans still
live on Planet Earth?
