"The two basic rocks found in the Mammoth Cave area are limestone and sandstone. Limestone is the "soft" rock (more water soluble) that is dissolved more easily by water. Sandstone and shale are the rocks that are on top of the cave. They are "harder" (less water soluble) and don't let the water soak into the cave."

Limestone does not belong, as it is primarily composed of calcite, while the other three - shale, sandstone, and basalt - are all composed of different mineral compositions (clay minerals, quartz, and basaltic minerals, respectively).
Sandstone: Formed from compacted sand grains. Limestone: Comprised of calcium carbonate from marine organisms. Shale: Made up of fine-grained sediment particles. Conglomerate: Consists of rounded rock fragments cemented together.
There are many different kinds of sedimentary rock. Four examples of this type of rock are shale, sandstone, limestone and coquina.
Limestone, shale, and sandstone are all sedimentary rocks formed through the accumulation and compression of sediments. They are all composed of mineral particles such as quartz, calcite, and clay minerals. Additionally, these rocks are commonly used in construction and as building materials due to their durability and strength.
Shale usually crumbles easily because it is composed of fine-grained clay minerals that lack cohesion. The rock's sedimentary nature means it has undergone compaction and cementation relatively less than harder rocks like sandstone or limestone. This makes shale prone to breaking into small pieces when stressed.
