This concept can simply called BREAKUP of Pangae.
At about 200million years ago , Pangae isn't quite Pan-Gae as Southeast Asia and China ,as well as portions of iran and tibet, have not quite attached.
Just as pieces of China are begining to attach,Laurasia (north America +Eurasia) breaks away.It is tempting to wonder if the two events might be connected.
Around 130-100 million years ago, Gondwana land break apart.At about 80 million years North America and Eurasia Splitted apart.
Then Greenland with Europe was attached to North american Plate
the last major breakup happened 50 million years later Australia Breaked up frm Antartica
And in these Transformations great Mountains,Hills and River were formed .,.,(i.e Himalaya,Nile and many more)
THese can be the following comments on it
