What are the proposed hypothesis of Alfred Wegener about the formation of continents?
Wegener’s Continental Drift Hypothesis Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. Wegener put his idea and his evidence together in his book The Origin of Continents and Oceans, first published in 1915.
What did Alfred Wegener call his hypothesis?
Alfred Wegener, in full Alfred Lothar Wegener, (born November 1, 1880, Berlin, Germany—died November 1930, Greenland), German meteorologist and geophysicist who formulated the first complete statement of the continental drift hypothesis. …
What happens when oceanic crust collides with continental crust quizlet?
When two plates carrying oceanic crust collide the more dense crust sinks under the less dense one and creates a trench. When two continental plates collide they form mountain ranges and volcanoes. When an oceanic and continental plates collide the more dense oceanic crust sinks under the less dense continental crust.
When two plates carrying continental crust collide What is it called?
At convergent boundaries, tectonic plates collide with each other. The events that occur at these boundaries are linked to the types of plates — oceanic or continental — that are interacting. Subduction Zones and Volcanoes. At some convergent boundaries, an oceanic plate collides with a continental plate.
What happens when oceanic crust collides with continental crust at a plate boundary a the continental crust moves closer to the mantle B the oceanic crust floats above the continental crust C some oceanic crust is consumed into the mantle D fresh oceanic crust is formed?
Oceanic crusttends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
