Plate Tectonics and Continental Drift Theory

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• The would all decrease.
• They would stay the same.  
• Temperature would decrease, but pressure and density would increase. 

Plate movement is caused by ______________.

• the rotation of the Earth
• ocean tides
• convection currents in the mantle
• the moon's gravity

Who is the person credited with developing the theory of continental drift?

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

This layer of Earth is the thickest part

• crust
• outer core
• mantle
• inner core

Earth's plates are...

• constantly moving and changing the face of the earth
• Never moves
• Moves seldom and very fast
• Moves when it feels like it

What was the name given to all the continents when they were joined as one super continent? 

• Supreme Continent
• Eurasia
• Plate tectonics
• Pangea

Which of the following occurs because of convection currents?

• Tectonic plates on the crust move.
• The mantle increases in size.
• Pressure in the crust increases.
• Pressure in the crust decreases.

Scientists think that convection currents that move the plates flow in Earth's

• Continental crust
• Oceanic crust
• Asthenosphere
• Lithosphere

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• The would all decrease.
• They would stay the same.  
• Temperature would decrease, but pressure and density would increase.
