the\u00a0<strong>distribution of the oceans and the continents.<\/strong>\n<ul class=\"wp-block-list\">\n<li>According to the theory,&nbsp;<strong>all the continents formed a single continental mass- Pangea and mega ocean- Panthalassa surrounded it.<\/strong><\/li>\n\n\n\n<li>Pangaea started splitting and broke down into two large continental masses as&nbsp;<strong>Laurasia and Gondwanaland<\/strong>&nbsp;forming the northern and southern components respectively.<\/li>\n\n\n\n<li>Subsequently,&nbsp;<strong>Laurasia and Gondwanaland continued to break into various smaller continents that exist today.<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>The Continental drift must have moved&nbsp;some animals from&nbsp;one continent to&nbsp;others and few getting stuck&nbsp;in the
