What is the opening formed when acid groundwater dissloves limestone?
The opening formed when acid groundwater dissolves limestone is called a karst landscape. This process creates features such as caves, sinkholes, and underground rivers due to the chemical weathering of limestone by acidic water.
What does groundwater naturally contain that allows it to dissolve limestone and from caverns?
Groundwater naturally contains carbon dioxide, which forms carbonic acid when mixed with water. This weak acid dissolves the limestone, creating cavities and caverns over time through a process called chemical weathering.
What rock type is typically needed to sculpt the landscape using groundwater?
Groundwater (ie water in the ground rather than precipitation as rain or snow) causes landscape features in carbonate rocks (Limestone) which it dissolves. The topography produced in Limestone areas is called 'Karst Topography'.
How does underground caves form?
Carbon dioxide mixes with groundwater making a weak acid that can only dissolve limestone. As it travels through limestones natural cracks and pores it enlarges them until an opening is formed called a cave
How does the floor of a limestone cave form?
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.
What happens when weak acids in ground water come into contact with limestone?
Limestone (CaCO3) in the presence of acid converts into carbon dioxide and ions of cacium. The chemical formulae are: CaCO3(s) + H3O+(aq) = Ca2+(aq) + HCO3-(aq) HCO3-+ H3O+(aq) = CO2(aq) + 2 H2O(l) H3O+(aq) + CO32-(aq) = HCO3-(aq) + H2O(l)
What are permeable and porous rock layers thet can hold and transmit groundwater?
Permeable rock layers such as sandstone, limestone, and fractured volcanic rock can hold and transmit groundwater. Porous rock layers like sandstones, conglomerates, and fractured limestone allow for the storage and movement of groundwater due to their interconnected pore spaces.
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 and where do most caverns form?
Most caverns form through a process called speleogenesis, which occurs when groundwater dissolves limestone or other soluble rocks over millions of years. These dissolved materials create openings and passages underground, eventually forming caverns. The most common locations for cavern formation are in areas with thick limestone deposits, such as karst regions.
How are caves formed in limestone?
Limestone caverns are formed when the acid in the rain drops or sea water erodes the stone through attrition and eliminates to rock. Limestone is a permeable rock - which means it can soak up liquid, like a sponge.
There are underground caverns in the Yucatán Peninsula because?
the peninsula is primarily made of limestone, a type of rock that easily dissolves in water. Over time, rainwater seeped through the limestone, creating underground channels and caverns through a process called karstification. This geological process is responsible for the formation of the caverns in the Yucatán Peninsula.
How do underground limestone caves form?
Dissolution of the limestone by rain & snow-melt water slightly acidified by absorbed atmospheric carbon dioxide. It oozes through the rock's joints, bedding-planes & other discontinuities from surface to rising (spring). Eventually these initial micro-conduits start to coalescence and develop discrete passages.
