All over the place!
** The principle caving areas, from North to South, are:
The NW Pennines (the largest and with the most caves)
Peak District (Derbyshire)
Forest of Dean
South Wales - esp. Mynydd Llangattwg and near Swansea
Mendip
South Devon.
** Then there are various other scattered areas with fewer but still interesting caves. Again, N to S;
Assynt (Scotland)
Isle of Skye and Applecross
Northern Pennines, N.York Moors and various parts of the extensive Permian outcrop and the NE end of the SW-NE coast-coast Jurassic limestone band (Excalibur Pot).
Morecambe Bay / Furness
North Wales
Portland (karst, mass-movement and sea- caves).
** Various isolated caves in minor outcrops of limestone, and surface karst features, including:
Knapps Quarry Cave, all on its own near Combe Martin, N. Devon.
A small phreatic relict nr Bridport, w. Dorset.
Karst features on the Jurassic outcrop including an active swallet in Wiltshire. Surface karst features in Lincolnshire and vague traces on the Cotswolds. The marker stone for the "Source of the Thames" is rather bizarrely next to a shallow doline right up on the Cotswold Hills!
Also a few caves and other karst features in the Chalk: e.g., Beachy Head Cave, and Culpepper's Dish and numerous smaller dolines on the Dorset Heath.
No, not all caves are made of limestone. Caves can be formed in various types of rocks, including granite, sandstone, and volcanic lava flows. Limestone caves are common because limestone is soluble and can be eroded by water to create cave systems, but caves can also form in other types of rocks through different geological processes.
Limestone Caves e.g The Marble Arch Caves in Northern Ireland(Fermanagh)
They are both caves
Other way round! Water and/or air are in caves.:-) Most of the world's caves have formed / are forming in limestone.
A stalactite is a structure that hangs from the ceiling of a cave and is formed by the precipitation of minerals from dripping water.
Limestone is the rock that is in Caves. When carbonate acid is reacted to the limestone in the caves, it will corrode forming strange caves landforms.
Limestone is formed in caves through a process called cave formation or speleogenesis. This occurs when water containing dissolved minerals, like calcium carbonate, seeps through cracks in the rock and evaporates, leaving behind deposits of limestone. Over time, these deposits can accumulate to form intricate cave structures.
Limestone caves are common because limestone is a soluble rock that dissolves easily in water. Over time, groundwater flowing through cracks in the limestone gradually enlarges these passages to form caves. Additionally, limestone is often found in areas with karst topography, characterized by sinkholes, underground rivers, and other features that promote the formation of caves.
Limestone caves are formed through a process called karstification, where rainwater picks up carbon dioxide from the air and soil, creating a weak carbonic acid. This acidic water dissolves the limestone rock over time, creating underground cavities and passages. As the water drains away, it leaves behind caves and unique formations such as stalactites and stalagmites.
generally, in limestone uplands, where the limestone is sufficiently massive to hold caves, and particularly but not exclusively where the local surface drainage can concentrate rainwater into discreet streams than can then form sink caves when they flow onto the limestone.
Limestone is a type of rock that is easily eroded by water, which can create caves over time. Water dissolves the limestone rock to form caves through a process known as chemical weathering. Additionally, limestone can also be carved out by underground rivers or other natural forces, resulting in the formation of caves.
Yes Missouri is famous for its limestone caves.
