Plate Tectonics and Pole Reversal

What is Pole Reversal?

• When the north pole and south pole switch places

• When because of magnetic reversal the north pole switches on a compass to the south pole

• When because of magnetic reversal the north pole and south pole switch places

• When the compass shows north in the wrong direction

On average how long does it take for a pole reversal to occur?

• About 200,000 to 300,000 years

• 1-2 million years

• 20 million years

• 600,000-800,000 years

How long has it been since the last pole reversal?

• 700,000-800,000 years

• 200,000-300,000 years

• 400,000-500,000 years

• 500,000-600,000 years

What was the last Pole Reversal called?

• The last pole reversal

• Pangea

• Matuyama-Brunhes reversal

• Brunhes-Matuyama reversal

What is continental drift?

• Pangea

• The 7 continents

• Movement of continents across the earth's surface overtime

• large pieces of land moved

What has this definition "cracks in the earth's crust along which movement occurs"?

• faults and fractures

• cracks

• earthquakes

• mountains
