Which of the following is a feature of limestone regions?
Answer Details
Stalagmites are features of limestone regions. Limestone is a sedimentary rock formed from the accumulation of organic and inorganic materials, such as the remains of marine organisms and minerals, over time. It is composed primarily of calcium carbonate. Limestone regions are characterized by karst topography, which is characterized by sinkholes, caverns, and underground drainage systems. Stalagmites are formed in caves as a result of water dripping from the cave ceiling, depositing calcium carbonate on the cave floor over time. The resulting cone-shaped deposit grows upwards from the cave floor, forming a stalagmite.
