What process describes the production of layers of sediment?

1. Recrystallization

2. Weathering

3. Erosion

4. Metamorphism

The correct answer is: Erosion

The production of layers of sediment is best described by the process of erosion. Erosion involves the removal and transportation of soil and rock materials from one location to another, often by wind, water, or ice. As these particles are moved, they can accumulate in various environments, such as river beds, lakes, or ocean floors. Over time, these sediments can build up in layers, creating sedimentary deposits. While processes like weathering and metamorphism play important roles in the rock cycle, they do not primarily focus on the formation of sediment layers. Weathering refers to the breakdown of rocks into smaller pieces, and metamorphism involves the transformation of existing rocks under heat and pressure, rather than the accumulation of sediments. Recrystallization is a specific type of metamorphic process where minerals change in size and shape but does not contribute directly to sediment layer formation. Therefore, erosion is the key process responsible for the production of layers of sediment.
