Hello friends.....
underground passages and caves are found in rocky landscapes across the world. They are common in areas with a lot of limestone.
cave systems from when acidic water etches its way through rock. Rainwater becomes acidic when it takes in carbon dioxide from the atmosphere, while groundwater can pick up acids from soil. the water causes existing cracks in the water flows through, creating channels. over time, the following water opens up passages and caverns, and more rocks weaken and fall, creating larger caverns.
the surfaces of these caverns can become covered with a variety of crystalline deposits, which from when mineral,- enriched water evaporates. leaving behind solid structures called stalactites and stalactites.
Inside Earth.....
The gradual weathering of limestone rock by acidic water can create incredible cave system. over thousands of years, small caves steadily grow, creating huge interlinked networks are created, filled with thousands of stalactites and stalagmites.
karst....
Bare limestone - rock landscapes produced by chemical weathering are called Karst. They feature deep trenches and Sharp limestone pinnacles.
how gorges form...
The development of cave system means large amount of limestone rock is removed from a landscape. underground cavities are enlarged by rock falls and form caves. Eventually, the caves roofs collapse, creating sinkholes, which can then merge to form larger sunken regions with steep sides, known as gorges.
The cave system is a very wonderful and artistic, perfect and profitable beneficial system of our ancient times. In ancient times, it was used to make a confidential route and to protect it from war.
