Fresh warning as experts say Pacific Ocean closing off to form new super continent

"Here we address this question through 4-D geodynamic modelling using realistic tectonic setups.”The world's oldest known supercontinent, Nuna, came together about 1.8 billion years ago, and Chuan Huang, from Curtin's Earth Dynamics Research Group says a supercontinent is due to form in a "couple of hundred of million years' time".He said: “Over the past 2billion years, Earth's continents have collided together to form a supercontinent every 600million years, known as the supercontinent cycle.
