The nature of the rocks reveals their origins. Geologists believe that "the present is the key to the past." After observing lava erupting from a present-day volcano or limestone forming in marine waters, we infer that similar types of ancient lavas or ancient limestones formed in virtually the same ways.Expert Answer.

For buildings constructed in the 1800s, power tools did not exist, so they had to get creative with their stone cutting techniques. Luckily, limestone is relatively soft compared to other stones and cuts more easily.
Limestones originate by three main processes: (1) precipitation of calcium carbonate in an initially stony condition, as in travertine and organic reefs; (2) lithification of calcium carbonate sediments, which includes various steps beginning with changes of grain mineralogy, and includes addition of concentric coatings to grains, selective dissolution of matrix and/or grains, precipitation of ...
