Plate Tectonics

This layer of Earth is the thickest part

• crust
• outer core
• mantle
• inner core

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.
