The Hadrian's Wall is primarily constructed from local stone, specifically limestone and sandstone. The stone was quarried from nearby areas, with limestone being predominant in the eastern sections and sandstone more common in the western parts. This choice of material contributed to the wall's durability and integration with the surrounding landscape.
Iron-rich limestone can range in color from rusty red to brown or yellow, depending on the amount of iron present. The iron minerals in the limestone can oxidize and create different hues of color.
Carbon dioxide is a colorless gas.
It depends on the location, if the limestone wall is on the coast, ocean waves would cause it, if it's inland in Mexico or Florida for example.....slightly acidic rain water trickling down through the layers would dissolve the limestone creating caverns and stalactites and stalagmites. What causes the acidic water? Namely plants and decomposing matter that dissolve in the water from up above. Volcanic activity and pollution can cause acidic rain as well.
The common name for limestone is simply "limestone".
