The lithosphere comprises the Earth’s

crust and uppermost mantle.

Colliding heat particles result in

thermal expansion which causes a

fracture between the dense and

lesser-dense areas.

When plates collide perpendicularly,

they can be destroyed causing the

denser oceanic crust of one plate to

submerge and fall under the lighter

continental crust of the other plate.

As the top plate is consumed by the

mantle beneath it, it melts and the

crumbles upwards to form a mountain

range.
