The limestone rock in the attached 3D model appears to have a lighter color and smoother texture compared to granite. Limestone is composed mainly of mineral calcite, while granite is a coarse-grained igneous rock made up of multiple minerals such as quartz, feldspar, and mica. Limestone is formed primarily from the accumulation of marine organisms' shells and sediment, while granite is formed through the solidification of molten rock deep within the Earth's crust. Limestone is softer and more porous compared to granite, making it more prone to weathering and erosion.
