Pacific Ocean shrinking, may form new supercontinent in 300 million years

The Pacific Ocean, Earth's largest ocean, is slowly shrinking as tectonic plates converge along its edges. Subduction zones are consuming the ocean floor faster than new crust is being generated. Scientists estimate this process could close the Pacific entirely within 200 to 300 million years. The closure would draw continents together, potentially forming a new supercontinent called Amasia.
