Which best describes how wedge basins form?
A) When two plates move apart, the weaker part of Earth's crust moves down at normal faults where sediments are
deposited until a basin forms.
B) At the area where two bent plates slide past each other, a depression forms where sediments are deposited.
C) When two plates collide, the non-subducting plate scrapes the subducting plate and forms a depression where
sediments gather.
D) At the area of a depression between two plates, sediments continue to get deposited and become compacted.

The option that best describes the formation of wedge basins is C, " When two plates collide, the non-subducting plate scrapes the subducting plate and forms a depression where sediments gather."

In geography, a basin is considered to be any major depression of the Earth's crust. These basins can be of six types:

Forearc
Foreland
Passive margin
Rift
Strike-slip
Wedge

all of these are caused by the interaction between large portions of the Earth's surface.

A wedge basin is formed when two plates collide, the non-subducting plate scrapes the subducting plate and forms a depression where sediments gather, being described perfectly by option C.
