I have no words but you are on target i guess
Yes, the rock formed by the pressure-induced transformation of layers of mud is indeed sedimentary rock. To understand why, let's break it down:
1. Sedimentary rock formation: Sedimentary rocks are formed through the processes of deposition, compaction, and cementation of sediments. Sediments can include particles like sand, silt, clay, and organic materials. Over time, these sediments accumulate in layers and undergo geological processes that result in the formation of sedimentary rocks.
2. Mud: Mud primarily consists of fine-grained particles, predominantly clay and silt, mixed with varying amounts of water. When mud is deposited in a suitable environment, it can eventually become sedimentary rock.
3. Pressure-induced transformation: As layers of mud accumulate over time, the weight of overlying sediments and the natural compaction process increase the pressure on the underlying layers. This pressure compresses the sediments and drives out excess water, causing the sediment particles to become densely packed. As a result, the mud undergoes the transformation into a more solid, compact, and layered rock known as shale.
Therefore, the answer to your question is that the rock formed by pressure changing layers of mud is sedimentary rock, specifically shale.
