Which geographical phenomenon includes volcanic, tectonic plate, and orogenic processes?

Correct answer: Diastrophism. Diastrophism is the large-scale deformation of the Earth’s crust, including folding, faulting, and mountain building.

Background: The word comes from the Greek diastrephein, meaning “to twist”.

• Erosion: Erosion is the wearing away of land.
• Weathering: Weathering is the breakdown of rocks in place.
• Deposition: Deposition is the laying down of material.

Did you know? Orogenic movement is the type that builds mountains.

Memory trick: Diastrophism = crust movements.
