Which set of processes can transform metamorphic rock into sediment?
Answer: To transform metamorphic rock into sediment, several key geological processes are involved. Here’s a step-by-step breakdown of these processes:
-
Weathering: This is the first step where the metamorphic rock is broken down into smaller particles. This can occur through physical weathering (like freeze-thaw cycles or abrasion) and chemical weathering (like acid rain or oxidation).
-
Erosion: Once weathered, these particles are transported away from their source by natural agents such as water, wind, or ice. This process gradually wears down the rock into finer sediment.
-
Transportation: The eroded materials are moved by rivers, oceans, glaciers, or wind to new locations. During this process, the particles can become more rounded and sorted by size.
-
Deposition: Eventually, the sediment is deposited when the transporting medium (water, wind, etc.) slows down, losing the energy required to carry the particles. This can occur in rivers, lakes, oceans, or even deserts.
-
Sedimentation: Over time, layers of sediment build up. With enough accumulation, these sediments can start to compact and cement together, eventually forming sedimentary rock.
Summary: Metamorphic rock transforms into sediment through weathering, erosion, transportation, deposition, and sedimentation. Each step gradually breaks down and relocates rock particles until they accumulate as sediment.
