Physical Geography

Which plate boundary is primarily responsible for the formation of deep ocean trenches and volcanic island arcs?

A river's discharge increases dramatically after a heavy storm. Which change to the river profile is most likely over several years?

Which process best explains how weathering and erosion together transform a plateau into a range of isolated hills over geologic time?

During continent-continent collision, which outcome is most likely for crustal thickness and surface elevation?

Which scenario best describes how rivers contribute to sediment delivery to a continental margin?

Which evidence would most strongly support past horizontal movement between two crustal blocks along a transform fault?

Erosion rates generally increase where vegetation cover is removed from slopes, leading to faster landscape denudation.

All mountain ranges form at plate boundaries; isolated volcanic islands cannot form far from plate margins.

River meanders migrate laterally over time because of faster flow and erosion on the outer bank and deposition on the inner bank.
