1. water seeps into cracks in the rocks and then freezes, as water turns to ice it expands cracking the rock

2. Hot sunshine followed by cold night temperatures makes rocks expand and then contract. This also makes the rock crack.

How will weathering affect a sandstone statue?

As cool as sandstone statues may look, it is inevitable that, if exposed to the elements, the statue will slowly be weathered away. The most likely culprits for statue weathering are wind and water, unless of course ice somehow gets involved. Regardless of what does it, the process will likely look the same. The sharpest, most defined features will be weathered away first. Either the wind will slowly eat away at the particles or the water will do the same. Think of a rough surface on a piece of wood. As you rub it continuously with sandpaper, it slowly becomes smooth and less defined. The same works with weathering. Over time, the beautiful statue of Caesar or Napoleon will become a featureless lump of sandstone.
