Front 10

is it true if the continents existed as Pangaea, the rocks found in a particular region on one continent should closely match in age and type those in adjacent positions on the adjoining continent

Back 10

true

Front 11

What is one objection that critics had about Wegner's continental drift hypothesis

Back 11

Wegner could not propse a mechanism capable of moving the continents

Front 12

It is true or false that most scientists in Wegner's time supported his continental drift hypothesis

Back 12

false

Front 13

It is trye or flase that Wegner propsed that during continental drift, larger continents broke through the oceanic crust

Back 13

true

Front 14

By 1968, data collected about the ocean floor, earthquake activity, and the magnetic field led to a new theory called
