Statement 1 is correct: Rocks are continuously undergoing transformation through the rock cycle (igneous to sedimentary, sedimentary to metamorphic, etc.). They are not static entities. Statement 2 is correct: Transformation is indeed caused by various processes. Weathering and erosion break down rocks, which is a necessary step in the formation of sedimentary rocks. Metamorphic action (heat and pressure) directly transforms existing rocks into metamorphic rocks. These processes are key drivers of the rock cycle.
