成人快手

Why what are now mountains may once have been under the sea. Fossils have been found on the tops of some of the world's highest mountains, which would suggest they were pushed up by an unbelievable force. The programme provides an explanation of how moving continents pushed up the earth's crust to create mountains and oceans.

This is a programme from the 成人快手 World Service Archive and was originally broadcast in 1998.
