Plate Tectonics

Who was the German meteorologist and geophysicist who proposed the "Continental Drift Theory"?

• Alfredo Wegener

• Alfred Wegener

• Alfred Wagener

Continental drift theory suggests that a single supercontinent called Pangaea existed millions of years ago. What do you mean by the Greek word "Pangaea"?

• all lands

• both lands

• same lands

How did Wegener arrive at the idea of "Continental Drift Theory"?

• He presented evidences which are continents are near to each other, share different languages and culture and having the same beliefs.

• He presented evidence which are continents have unities in trading system, same rules or laws which they impost and they share same oceans to have resources.

• He presented evidences which are continents fit together like a jigsaw puzzle, there are some identical fossils in the different continent and they share common geological features.

What do you call to the other plates that are smaller compare to the major plates?

• macroplates

• microplates

• middle plates

What is the type of plate which are made up of silica-magnesia-rich material or basalt?
