The ever-changing world we now live shows its evolution because of Plate tectonics forming braking up and reforming land masses on this planet. The Earth’s earliest supercontinent was Vaalbara and it was formed around 3.2 to 3.5 billion years ago. Then 3 billion years ago Ur assembled and is the smallest of supercontinents. Then 2.7 billion years ago the third supercontinent Kenorland was assembled and was responsible for one of the planet’s greatest climate disasters essentially it also allowed for life as we know it to exist. Then around 1.8 to 1.9 billion years ago the supercontinent Columbia, also known as Nuna was assembled. Then around 1.3–0.9 billion years ago the supercontinent Rodinia was assembled. Then around 650 to 600 million years ago the supercontinent Pannotia, also known as Vendian was assembled. Then around 300 million years ago the supercontinent Pangaea or Pangea was assembled.
