Document Summary
Physical geography is concerned with the process that shape earth"s landforms, climate and vegetation. The processes that create the world"s varied landforms - mountain ranges, continents, and the deep ocean floor - are some of the most powerful and slow-moving forces on the planet. Internal processes can move entire continents, often taking hundreds of millions of years to do their work. External processes form many of earth"s landscape features, such as beautiful waterfall or a rolling plain. Geomorphologists study these two processes that constantly shape and reshape. Two key ideas related to internal processes in physical geography are the pangea. The geophysicist alfred wegener first suggested the pangaea hypothesis in 1912. Proposes that all the continents were once joined in a single vast continent called. Pangea (meaning all lands ), which then fragmented over time into the continents we know today.
