The North and the South America will “squeeze” together, and the Caribbean Sea and the Arctic Ocean will disappear. It was concluded in a new study that Asia and America will merge.
Researchers are examining the changes that will be happening over several tens of millions of years. Geologist Zeng-Xiang Li, after an earthquake, traveled to Nepal in order to use new seismic instruments and study collisions between the Indian and Eurasian tectonic plates.
Why Amasia? The idea of the Earth forming a new supercontinent, named Amasia is not new. But available seismological devices and techniques enable experts to study those changes in more detail. Although scientists agree that the process of supercontinent formation is already happening, the subject of the debate is exactly where it will be formed.
The North and the South America will “squeeze” together, and the Caribbean Sea and the Arctic Ocean will disappear. It was concluded in a new study that Asia and America will merge. These changes will be visible in 50 to 200 million years. Despite the fact that Indian plate is already merged with the Eurasian plate, it keeps moving towards north, a couple of centimeters per year, which causes tectonic activity.
However, other continents are moving towards each other as well. Each year, a couple of centimeters of the Pacific Ocean disappears, which will eventually end up in merging America and Eurasia. Australia is moving 7.8 centimeters per year towards Asia, and it will also merge with Eurasia.
“It will take at least 10 million years, maybe even hundreds of millions of years, for the changes to happen”, said Li
Scientists can compare this process to the previous supercontinent Pangaea, which was formed around 1.3 billion years ago. It broke into seven continents and resulted in the birth of the Atlantic Ocean about 100 million years later.
Researchers believe that Pangaea was the third one of four supercontinents in the Earth’s history. Seven major and several minor tectonic plates formed the Earth’s surface. These plates are moving at various speeds, from a few millimeters to two centimeters per year, which is the speed of human fingernails growth.
