* Weathering is the process of breaking down rocks into smaller pieces. This can happen through physical weathering (like frost wedging) or chemical weathering (like acid rain).

* Metamorphic rocks are rocks that have been transformed by heat and pressure.

* Sediments are small pieces of rock, minerals, or organic matter that are created by weathering.

Therefore, weathering can break down metamorphic rocks into smaller pieces, which are then considered sediments.
