Layer & # 39; out of the World, solid shell that depart on, is made from broken pieces, such as shell & # 39; broken egg. These pieces, the tectonic plates, moving around the planet in & # 39; & # 39 speeds, a few centimeters a year. Every so often come and join & # 39; supercontinent, which remains & # 39; a few hundred & # 39; & # 39 million; years before breaking down. The plates are then dispersed or spread and go & # 39; apart, until eventually – after 400-600 million years – bringing together again.
The last supercontinent, Pangea, formed about 310 million years ago, and began to declare about 180 million years ago. It has been suggested that the next superkontinent will form f & # 39; 200-250 million years, so we now we are halfway the dispersed phase of the current cycle & # 39; superkontinent. The question is: how will form the next superkontinent, and why?
There are four & # 39; basic scenarios for the formation of the next superkontinent: Novopangea, Pangea Ultima, Aurica and Amasia. As each form depends on different scenarios but, ultimately linked to & # 39; as Pangea separated, and as the world's continents are still moving today.
The breakup of & # 39; Pangea led to the formation of & # 39; the Atlantic Ocean, which is still open and is becoming more widely & # 39; today. Consequently, the Pacific Ocean was closed and more restricted. The Pacific is home to circle & # 39; & # 39 areas; subduzzjoni along its edges (the fire circle), where the ocean floor or drop deductible under continental plates and inside the Earth interior. Here, the ancient ocean floor is recycled and can & # 39; enter into & # 39; qajliet volcanic. Atlantic, b & # 39; contrast, has a great ocean line to produce new ocean plate, but it is only home to two areas & # 39; subduzzjoni: the Ark of the Lesser Antilles in the Caribbean and -Ark of & # 39; Scotja between America t & # 39; South and Antarctica.
Assuming that the present conditions persist, continue to the Atlantic & # 39; open and the Pacific remains & # 39; closes, we have a scenario where the next superkontinent forms at antipodi of & # 39; Pangea. The Americas will collide with the north & # 39; Antarctica to the north, and then to Africa Eurasia already crashed. The superkontinent then forms a Novopangea been named, or Novopangaea.
