Subduction of oceanic plates

Rifting of a supercontinent called Pangaea

Collision of continental plates

Formation of volcanic islands

Both plates consist of oceanic lithosphere

Both plates consist of continental lithosphere

One plate subducts beneath the other

Plates move apart, forming a mid-ocean ridge

It becomes thinner and less dense

It becomes cooler, denser, and accumulates more sediment

It becomes hotter and less dense

It remains unchanged

The oceanic plate is pushed down under the continental plate, forming trenches and volcanoes.

The continental plate is pushed down under the oceanic plate, forming mountains.

Both plates move away from each other, forming rift valleys.

The plates move parallel to each other, forming fault lines.

Formation of deep ocean trenches.

Formation of high mountain belts with folded and faulted rocks.

Formation of volcanic islands.

Formation of flat plains with no geological activity.

Rift valleys.

Oceanic trenches.

Fault lines.

Plateaus.

They are the tallest and deepest mountains in the world, growing at a rate of about 1 cm/year.

They are formed by volcanic activity and grow at a rate of 10 cm/year.

They are underwater mountain ranges formed by oceanic plate collisions.

They are flat plains formed by erosion over millions of years.

They are shallow valleys formed by erosion.

They are deep, arc-shaped valleys marking the boundary between two plates.

They are flat plains formed by sediment deposition.

They are volcanic islands formed by magma cooling.
