The average density of one crustal plate is 2.8 g/cm^3 and the average density of an oceanic plate is 3.2 g/cm^3. If these two plates came together, what could be expected to happen?
The two plates would push apart and form a rift zone
The oceanic plate would rise up over the continental plate
The oceanic plate would be pushed under the continental plate
The two plates would meet head on and rise up to form mountains

Both the temperature and pressure increase
Both the temperature and pressure decrease
The temperature decreases and the pressure increases
The temperature increases and the pressure decreases

Scientists believe the Earth's inner core to be solid. This is probably due to extremes in?
Depth
Density
Pressure
Temperature
The Earth's mantle is made up of very hot material that rises to the top of the mantle, cools, then sinks, reheats, and rises again, constantly repeating the cycle. This action, which causes the Earth's crust to move is known as?
