Caves are one of the types of landforms created by groundwater erosion. Working slowly over many years, groundwater travels along small cracks. The water dissolves and carries away the solid rock. This gradually enlarges the cracks.

How caves are formed in ground water?
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Can erosion create caves?
Sea caves or littoral caves are formed primarily from erosion caused by waves. They can be formed along the ocean coast and lakeshores where water impacts bedrock. Most sea caves are formed along weaknesses in the rock, such as faults, fractures, or bedding/foliation planes and can occur in nearly every type of rock.

Are caves formed by weathering or erosion?
These caves are formed by the dissolving of the rock along and adjacent to joints (fractures), faults, and layers in the rock. The processes involved are both chemical corrosion and physical erosion.

Are caves caused by wind erosion?
Erosional caves are those formed by the action of water or wind, carrying abrasive particles capable of carving rock. With respect to water, the processes involved are very much like those when a surface canyon is carved, and such speleogens as fluting and potholes may be formed.

What type of weathering can create caves?
Sometimes, chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst. In these areas, the surface rock is pockmarked with holes, sinkholes, and caves.

How does water get into underground caves?
Most water that enters the cave comes down through the joints, which connect the cave with the surface. Where there are many joints, sinkholes can form on the surface. Sinkholes act like funnels, collecting rain water from the surface and funneling it into the cave.

Are caves formed by wind or water?
A cave is defined as an opening in the earth large enough to hold a person. Most caves are created when slowly-moving water dissolves, or eats away at limestone rock, creating spaces, caverns, and tunnel-like passages.
