Limestone forms in such a way that there are often blocks, as there are cracks perpendicular to the strata. These cracks allow water to actually flow. When the water flows, it dissolves calcite from the limestone, making the crack more pronounced. Water can flow vertically and horizontally in this way. This, after many years, erodes large caverns in the rock.
Limestone bedrock is commonly found in regions with caves and sinkholes. Limestone is susceptible to erosion by slightly acidic groundwater, which can create underground caves and cavities over time. Sinkholes often form when the roof of a cave collapses, leading to the characteristic landscape features in such regions.
Sandstone is the rock type most likely to contain fossils, as it is formed from compacted grains of sand that can preserve the shapes of organisms. Granite, marble, and basalt are less likely to contain fossils, as they are formed through processes that typically do not preserve organic remains.
Most basalt is found in the oceanic plates. Most granite is found in the continental plates.
Exposed limestone in southern Florida would weather faster than exposed granite in northern Canada due to several factors. Limestone is more susceptible to chemical weathering, particularly from acidic rain and humidity, which are prevalent in Florida's subtropical climate. In contrast, granite is a harder igneous rock that weathers more slowly, and the colder climate of northern Canada can limit the effects of physical weathering processes. Thus, the combination of limestone's composition and Florida's warm, humid conditions accelerates its weathering compared to granite in a cooler environment.
The three major classes of rock that you would expect to find as bedrock in Mount Shasta are metamorphic rocks, igneous rocks (such as andesite, dacite, and basalt), and sedimentary rocks. Metamorphic rocks would likely include schist, gneiss, and marble, while igneous rocks might be found in the form of lava flows and volcanic rocks. Sedimentary rocks like limestone and sandstone could also be present in the region.
A warm and humid climate would lead to rapid soil formation from limestone bedrock. The combination of warmth, moisture, and chemical weathering would accelerate the breakdown of the limestone and the formation of soil.
sedimentary bedrock
karst topography will contain mostly easily erodable bedrock, such as limestone and dolomite.
Soil would form fastest from limestone bedrock in a humid and warm climate. These conditions promote faster chemical weathering of the limestone, leading to the development of soil at a quicker rate compared to dry or cold climates.
Sedimentary rock and igneous rock would most likely have a zone of contact metamorphism between them. When molten magma intrudes into the surrounding rock, the heat and fluids released can alter the mineral composition of the adjacent rocks, leading to contact metamorphism.
All kinds, but by far the most common is granite. Granite is North Carolina's bedrock. If you were to dig down about six to eight feet you would find granite.
Marble as it is a carbonate rock which is soluble in acids.

If you find a piece of granite in an area where the local bedrock is sandstone, limestone or some other rock you could deduce that the granite was not local to the area but was probably either a glacial eratic or had been moved there by people. the same would apply to any rock which wasn't local to the area in which it was found.
