rock boulder 3d model

Characteristics of the Rock: • Smooth, rounded surface — Water currents carry sand and gravel, eroding sharp edges and making them rounded and slippery to the touch. • Flat or slab-like shape — Often found in layered rocks or rocks fractured along natural strata, giving them a plank-like appearance. • Darker color when wet — The actual color becomes more vibrant, such as dark gray, brown, or dark green from thin layers of moss. • Dense, hard surface — Because soft rocks are eroded quickly, the remaining rocks are usually hard rocks such as hard sandstone, granite, or basalt. • Some rocks have small grooves — These are formed by swirling water currents creating pathways in the rock's surface.
