Why do caves only form a certain type of rock?
Caves are formed by rainwater dissolving away limestone or sandstone.
What kind of weathering has created most limestone caves?

How is limestone worn away?
Limestone can be worn away through a process called chemical weathering, where rainwater and acidic pollutants cause the rock to dissolve slowly over time. Physical weathering, such as freeze-thaw cycles and abrasion by wind and water, can also erode limestone by breaking it into smaller pieces. These processes combine to create features like caves, sinkholes, and cliffs in limestone landscapes.
Water often passes through beds of limestone because?
limestone is a permeable rock that allows water to flow through its cracks and pores. As water moves through limestone, it can dissolve the rock, creating caves, sinkholes, and underground rivers. This process is known as karstification.
How are limestone caves and sea caves alike?
They are both caves
Is rainwater a weak acid that dissolves limestone to form caves?
yes
Where can limestone caves befound?
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.
Why do caves only form a certain type of rock?
Caves are formed by rainwater dissolving away limestone or sandstone.
Why there are large caves and tunnels where the main rock is limestone?
Limestone, CaCO3, is reactive with naturally acidic rainwater which helps dissolve it.
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 type of rock is usually present in areas with a lot of caves?
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
What process hollows out limestone in caves?
The process that hollows out limestone in caves is called chemical weathering. This occurs when rainwater combines with carbon dioxide in the atmosphere to create a weak carbonic acid, which gradually dissolves the limestone over time, resulting in the formation of caves and caverns.
What type of rock is usually present in area with a lot of caves?
Limestone is the most common type of rock present in areas with a lot of caves. This is because limestone is easily dissolved by acidic groundwater, forming caves through a process known as karstification.
What are the different kinds of caves?
The most common types of cave are limestone caves.
What kind of weathering has created most limestone caves?
chemical weathering called karsting and it createskarst topography. ... Dissolution of soluble limestone creates limestone cavessource yahoo answers
How lime- stones caves formed?
Limestone caves are formed through a process called chemical weathering. Rainwater, which is slightly acidic, dissolves the limestone rock over time, creating small cracks. These cracks then widen as more water flows through, eventually forming caves. Additionally, some limestone caves are formed through the erosion of underground rivers.
What are caves main materials?
Caves are mainly composed of rock materials such as limestone, sandstone, granite, and basalt. These rocks often have natural cracks or fissures that water can seep into and erode over time, forming cave systems. Additionally, caves may contain mineral deposits such as stalactites and stalagmites.
