Pangea formed due to the migration of continental plates (the regions of the crust that float on the liquid mantle), there is no reason ‘why’ the higher land masses collided and joined together to form a super continent, they just move around with the edges becoming eroded and new material forming all the time, eventually some of them will merge.
It is worth noting that the continent that now makes up most of China never joined Pangea.
As an aside, I believe that lakes are fresh water and seas are saltwater.
