Plate Tectonics Review

Wegener’s continental drift hypothesis stated that all the continents once joined together to form:

• 2 supercontinents
• 2 supercontinents and 3 small continents
• 1 supercontinent
• 1 supercontinent and 3 smaller contients

The supercontinent in the continental drift hypothesis was called: 

• Mesosaurus
• Africa
• Laurasia
• Pangea

One kind of evidence that supports Wegener’s hypothesis is that 

• same magnetic directions exist on different continents
• fossils of the same organism have been found on different continents
• major rivers on different continents match
• land bridges still exist that connect major continents

What was the main reason Wegener’s continental drift hypothesis was rejected

• He could not provide a mechanism for the movement of the continents
• His evidence was incorrect
• He could provide only illogical explanations for the movement of the continents
• He was not well liked by other scientists

The lithospheric plates move an average of:

• 50 inches per year
• 50 centimeters per year
• 5 inches per year
• 5 centimeters per year

What kind of plate boundary occurs where two plates grind past each other.in opposite directions?

• Convergent
• Bent
• Divergent
• Transform

A divergent boundary at two oceanic plates can result in a ____.

• plateau
• rift valley
• subduction zone
• trench

What type of boundary occurs where two plates move together, causing one plate to sub-duct or go under the other plate?

• Transform
• Divergent
• Convergent
• Bent

Which of the following is a geographic example of a transform fault boundary?

• San Andreas Fault in California
• East African Rift valley
• Andes Mountians
• Mid Atlantic Ridge

New ocean crust is formed at ____.

• convergent boundary
• transform boundary
• divergent boundary
• continental volcanic arc
