What is the role of weathering in the rock cycle?

• A. It forms new rock layers from molten material
• B. It erodes mountains to create plains
• C. It breaks down rocks into sediments for sedimentary rock formation
• D. It solidifies igneous rocks into metamorphic rocks

Answer: (C)

Weathering plays a crucial role in the rock cycle by breaking down rocks into smaller particles or sediments, which can then contribute to the formation of sedimentary rocks. This process occurs through physical, chemical, and biological mechanisms that alter the structure and composition of original rocks. When rocks weather, they are disintegrated into smaller fragments or dissolved minerals, which can be transported by water, wind, or ice and eventually accumulate in different environments, such as riverbeds, lakes, or oceans. Over time, these sediments can become compacted and cemented together, leading to the formation of sedimentary rock. Thus, the function of weathering is instrumental in transitioning materials within the rock cycle, enabling the continuous transformation and recycling of Earth's materials.
