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.

The statue of liberty turned green because of chemical weathering.
Dry climate ultimately. And no access to things that can scrape it especially water. Sandstone primarily contains Quartz and clays. Both will not weather under dry and wind free conditions.
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.
Weathering has affected the Statue of Liberty because the statue was once a coper color. Acid rain soon caused it to become a green color. Wind, water, snow, and the sun (forms of weathering) also caused the statue's natural color to wash away.
The original color of the Statue of Liberty was copper. The Statue of Liberty turned green because the weathering oxidized the statue.
The weight of a sandstone statue will depend on the size of the statue. Larger statues will weigh more than smaller statues. Sandstone generally weighs 150 pounds per cubic foot.
It is changing by weathering because when it rains a lot and the Statue of Liberty is made from a little bit iron, the iron gets wet and rusts the Statue of Liberty.
The Statue of Liberty is an example of a landmark that has been affected by weathering. Wind, rain, and snow have all affected the statue.
No, the column is granite, the sculpture on top is sandstone.
they crumble by acid rain and they rain makes hole in the statue they crumble by acid rain and they rain makes hole in the statue they crumble by acid rain and they rain makes hole in the statue
Marble is more sensible.
rebuild it
