Answer:
Rainwater absorbs carbon dioxide (CO2) as it falls. The CO2 combines with water to form carbonic acid. The slightly acidic water sinks into the ground and moves through pore spaces in soil and cracks and fractures in rock. The flow of water underground is groundwater. Groundwater is described further in the chapter Water on Earth.
When water sinks into the ground, it becomes groundwater
When water sinks into the ground, it becomes groundwater.[Figure2]
Groundwater is a strong erosional force, as it works to dissolve away solid rock (Figure above). Carbonic acid is especially good at dissolving the rock limestone.
Cave Formation
Working slowly over many years, groundwater travels along small cracks. The water dissolves and carries away the solid rock, gradually enlarging the cracks. Eventually, a cave may form (Figure below).

Sinkholes
If the roof of a cave collapses, a sinkhole could form. Some sinkholes are large enough to swallow up a home or several homes in a neighborhood (Figure below).

Groundwater Deposition
Groundwater carries dissolved minerals in solution. The minerals may then be deposited, for example, as stalagmites or stalactites (Figure below). Stalactites form as calcium carbonate drips from the ceiling of a cave, forming beautiful icicle-like formations. The word stalactite has a c, and it forms from the ceiling. Stalagmites form as calcium carbonate drips from the ceiling to the floor of a cave and then grow upwards. The g in stalagmite means it forms on the ground.
