Alfred Wegener, father of continental drift

Wegener thought that the continents were once connected. Continents fit into each other Landforms, like mountains Fossils of continents meshed in key areas People did not go along with theory, because they could not figure out what force would be strong enough to move a continent. Continents would crack if pushed through ocean Gravity would not make them go “downhill” Spin of the Earth was not fast enough Wegener died on expedition to Greenland Probably died by falling into a crevice When digging in Greenland, when you are are deep as you are going to go, one yells “I’ve found Wegener”. Theory widely accepted in early 1960’s

What kind of plate boundary is this a representation of?

What kind of fault is THIS a representation of?

Convergent zones can be Continent to continent (mountains) Continent to Ocean (ocean trench, and mountains) Ocean to Ocean (island arc ~ Japan)

This is oceanic vs. continental crust This is oceanic vs. continental crust. Name a place where this is happening.
