Which of the following is the best indication that limestone caves could be present at depth?
A) springs
B) cliffs and overhangs along rivers
C) large quartz crystals laying on the surface
D) gently sloping hills
E) limestone pillars and sinkholes
Limestone Caves
Natural cavities formed within limestone rock due to the dissolution of carbonate minerals by water, known for their unique formations and speleothems.
Quartz Crystals
Hard, crystalline minerals made of silica (SiO2), used in various applications due to their piezoelectric properties.
Sinkholes
Depressions or holes in the ground caused by the collapse of a surface layer, occurring in areas where the rock below is limestone, carbonate rock, salt beds, or other rocks that can be dissolved by groundwater.
- Determine the attributes of caves and karst landscapes, encompassing speleothems such as stalactites and stalagmites.

Final Answer :
E
Explanation :
Limestone pillars and sinkholes are direct indicators of karst landscapes, which are formed from the dissolution of soluble rocks, including limestone. This process can lead to the formation of caves, making E the best indication of potential limestone caves at depth.
