How was Yarrangobilly Caves was formed?
Yarrangobilly Caves were formed by the dissolving of limestone by acidic groundwater over millions of years. The caves contain various formations such as stalactites, stalagmites, and columns created by the deposition of minerals from dripping water. The underground chambers were ultimately carved out by the slow erosion process of water flowing through the limestone bedrock.
How natural caves are formed?
Natural caves are primarily formed through the process of erosion, typically by water. When rainwater seeps into the ground, it can become acidic by dissolving carbon dioxide, which reacts with minerals like limestone. Over time, this acidic water erodes the rock, creating cavities that can develop into larger cave systems. Other methods of cave formation include volcanic activity and the collapse of underground tunnels.
Can sandstone dissolve?
Yes, sandstone can dissolve over time when exposed to acidic groundwater or rainfall. The minerals in the sandstone can react with the acidic water, leading to dissolution and erosion of the rock. This process usually occurs slowly and can result in the formation of unique landforms like caves and sinkholes.
How are erosion caves formed?
Erosion caves are formed through the processes of chemical and physical weathering, primarily involving water. When acidic rainwater seeps into the ground, it can dissolve soluble rock, such as limestone, creating openings and passages over time. Continuous flow of water further erodes these openings, leading to the development of larger cave systems. Other factors, such as wind and temperature fluctuations, can also contribute to the erosion and shaping of caves.
How are snottites formed?
Snottites are formed in caves by much the same process as stalactites, except that snottites are composed of living bacteria, thriving on volcanic sulphur compounds contained in water dripping down over them from above.
What do you call caves made by water?
Karst caves, and it is the majority of caves; formed by acidic ground-water dissolving the limestone.
Why is the water in some caves highly acidic?
"Highly" might be a bit of an overstatement. Water in caves is frequently mildly acidic, because of dissolved organic acids and carbon dioxide, but it's generally not what would be considered highly acidic.
What type of chemical weathering is most evident in the US caves?
Same as in any caves of the same types anywhere in the world, which in karst caves is dissolution of the host limestone by weakly-acidic ground-water.
How does a acid cave form?
An acid cave forms when acidic groundwater dissolves limestone or other carbonate rocks, creating underground voids and passageways. Over time, the acidic water enlarges these cavities and forms unique underground features such as stalactites and stalagmites. Factors like the presence of carbon dioxide in the water contribute to the acidic conditions that lead to cave formation.
How do underground limestone caves for?
Underground limestone caves form through the chemical weathering of limestone rock by water that is slightly acidic. Over time, this process dissolves the rock and creates caverns and passageways underground. Factors such as the presence of cracks and fissures in the limestone, as well as the flow of water, contribute to the formation of these caves.
What types of erosion forms caves?
Caves are mainly formed through the process of chemical weathering, particularly the dissolution of limestone by acidic water. This process is known as karst erosion. Additionally, caves can also be formed through mechanical erosion, such as the action of flowing water wearing away softer rock layers.
How was waitomo caves made?
From god. +++ The question is "how", not "by whom"! They are still active, carrying a stream, so are still-developing karst caves in limestone, i.e. formed by dissolution of their host limestone by weakly-acidic water.
What type of rock is dissolved by slightly acidic groundwater?
Slightly acidic groundwater can dissolve limestone, which is a type of sedimentary rock made up of calcium carbonate. Over time, the acidic water can create underground caves and formations such as stalactites and stalagmites.
What are most caves made out of?
Most caves are made out of limestone, which is a sedimentary rock composed of calcium carbonate. This rock is easily dissolved by acidic water, leading to the formation of caves through a process called chemical weathering and erosion. Other types of caves can also form in volcanic or igneous rock, such as lava tubes.
How was Yarrangobilly Caves was formed?

The underground chambers were ultimately carved out by the slow erosion process of water flowing through the limestone bedrock.
Why most caves form by limestone?
Limestone is susceptible to dissolution by acidic water, which is common in most natural environments. Over time, this dissolution process carves out cavities underground, leading to the formation of caves. Additionally, limestone is a common and widespread rock type, which contributes to the prevalence of limestone caves.
What agent of erosion is responsible for creating limestone caves?
Water erosion, specifically through the dissolution of carbon dioxide in water to form weak carbonic acid, is the primary agent responsible for creating limestone caves through the process of chemical weathering. Over time, this acidic water dissolves the limestone, creating caves, sinkholes, and other karst topography features.
