Forces in Earth's Crust

Question 1 • RMA FL-2001310-Earth/Space Science Semester 2

Which best describes how wedge basins form?

Answer
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.

Explanation

Wedge basins form at convergent plate boundaries, where one plate is subducted beneath another. The overriding, non-subducting plate scrapes against the subducting plate, creating a depression that collects sediments. Choice C describes this process; choice A instead describes a basin formed as crust drops along normal faults.
