- 3710 - EARTH - in 300,000,000 years? The Pacific Ocean currently measures 6200 miles from one end to another and is shrinking at a rate of about a few centimeters per year. The formation of the next supercontinent will dramatically alter Earth’s ecosystem and environment.
--------------------- 3710 - EARTH - in 300,000,000 years?
- My birthday is coming up and the Pacific Ocean will be gone in 300 million years afterwards. I will miss the World's continents drifting and combining into a single continent.
-
- The Earth’s seven continents are distributed across the surface, with North and South America occupying one hemisphere, Africa, Europe, Asia, and Australia occupying the other, and Antarctica sitting alone around the South Pole.
-
- However, these continents were arranged in entirely different configurations throughout Earth’s history. They formed super-continents like “Gondwana” from 550 to 180 million years ago and “Pangaea” from 335 to 200 million years ago surrounded by “superoceans.”
-
- Eventually, the Earth’s tectonic plates will come together again to form this next supercontinent. This will happen roughly 200 to 300 million years from now. This will involve the Americas drifting westward until they collide with Australia and Asia eliminating the Pacific Ocean and Antarctica moving north to join them. This will give rise to the new supercontinent named “Amasia”.
-
- The research team ran a series of 4-D modeling on a supercomputer to simulate how super-continents form. These simulations took into account Earth-like plate tectonics and mantle convection over the course of a “supercontinent cycle,” during which the continents will separate and come together again.
-
- Over the past two billion years, Earth’s continents formed a supercontinent cycle every 600 million years, which means that they are due to come together again in a few hundred million years.
-
- The resulting new supercontinent has already been named Amasia because some believe that the Pacific Ocean will close as opposed to the Atlantic and Indian oceans when America collides with Asia. Australia is expected to play a role in this important Earth event, first colliding with Asia and then connecting America and Asia once the Pacific Ocean closes.
-
- The formation of Amasia will also mean the elimination of the Pacific Ocean, which is what remains of the Panthalassa superocean that surrounded the supercontinent Pangaea. The Pacific began to form 700 million years ago as Pangaea began to break apart making it the oldest ocean on Earth, and it has been shrinking ever since.
-
- The Pacific Ocean currently measures 6200 miles from one end to another and is shrinking at a rate of about a few centimeters per year. The formation of the next supercontinent will dramatically alter Earth’s ecosystem and environment.
-
- Earth as we know it will be drastically different when Amasia forms. The sea level is expected to be lower, and the vast interior of the supercontinent will be very arid with high daily temperature ranges.
-
- Today the Earth consists of seven continents with widely different ecosystems and human cultures. What will the world look like in 200 to 300 million years’ time?
