What type of rock is most commonly found in the Earth's crust?
Igneous rock
Metamorphic rock
Sedimentary rock
34% got this right

48 random squares
Which type of crust is denser: oceanic or continental?
Oceanic crust
Continental crust
48% got this right
Oceanic crust is denser than continental crust due to its composition, which is primarily basalt.

What is the process by which lithospheric plates move?
Plate tectonics
Convection currents
Mantle plumes
53% got this right
Plate tectonics is the process responsible for the movement of lithospheric plates on the Earth's surface.

What geological feature is formed when two lithospheric plates collide?
Mountain range
Ocean trench
Rift valley
Volcano
50% got this right
Mountain ranges are formed when two lithospheric plates collide, causing the crust to buckle and rise.
