What shape a rock would be weathered if there were no cracks in it?

If a rock has no cracks, it would likely weather into a more rounded or spherical shape over time. This is because weathering typically involves the gradual breaking down of surfaces and edges through processes like abrasion, freeze-thaw cycles, and chemical reactions. Without cracks, the rock's surface would erode evenly, leading to a smoother, more rounded appearance. Overall, the absence of cracks would influence the rock's weathering patterns, promoting a more uniform shape.
