Which process works with erosion to break down rock?

deposition

settling

transportation

weathering

The correct answer is - weathering.

The weathering and the erosion go hand in hand. The weathering is the process that manages to break up the rocks into smaller pieces, while the erosion is the process that is moving away the broken pieces from the place where the weathering took place.

In this way, the rocks lose their initial shape, break apart, and eventually disappear. But also, this processes enable the formation of the sedimentary rocks, as they are the ones that provide the material for their latter formation.

Option (4)

Explanation:

The weathering of rocks is usually defined as the break down of rocks. It disintegrates the rocks and forms smaller particles which are commonly known as sediments. This weathering that takes place can be of different types, such as-

Physical weathering Chemical weathering Biological weathering

This process together with erosion leads to the breakdown of rocks. Both these process creates sediments that again consolidates and lithifies and forms sedimentary rocks.

Hence, the correct answer is option (4).
