Why is limestone least resistant to weathering and erosion?
It is susceptible to chemical weathering more than other rocks from exposure to naturally acidic rainfall and groundwater.
Is limestone broken down in quarries to make building materials and other products?
Limestone is a valuable mineral resource. In its native form it makes for simple sawn stones of comfortable dimension. (Building blocks and pyramids.) As a chemical resource it is the major source of material for making Portland Cement, our common construction material. When limestone is baked to remove the water and the excess CO2, it becomes quick lime of value in agriculture. In this form, it is also used to bind clays in the substrate of roads. Similarly it finds use in many other industrial processes.
What rock Can only form underground?
What type of rock is formed from magma that hardens underground?
What is an example of an onomatopoeia that starts with the letter n other than neigh?

Where are all the map pieces to horrible histories awful egyptians?
click on the egyptian women and talk to her then click on the beard on the ground beside the other women and then click the 1 St women again then she will ask for crushed limestone because she ate sweets.go to the medicine stall and click on the limestone then go back to the and she will give you the map.then click on the piramids then on the jars at the very back of the tomb click on them and get the map piece.then click on the jars at the front play the game and get the map piece thats all ive got try and work out the other ones on your own. joanna x
Does carbonic acid cause the dissolution of limestone?
Yes, carbonic acid dissolves limestone as does any other acid. As carbonic acid is not a very strong acid this process is very sluggish, though.
List two kinds of rock that are easily weathered by carbonic acid?
Limestone and marble are two types of rock that are easily weathered by carbonic acid, which is a common acid found in rainwater. Over time, carbonic acid dissolves these rocks, leading to the formation of caves, sinkholes, and other karst topography features.
What is formed when carbonic acid dissolves underground limestone?
Caves, their stalactite and stalagmite formations (calcite by precipitation & crystallising of the calcium carbonate) - and scale in kettles etc using water that has passed through the limestone uplands.
The formation of Karst topography requires carbonic acid to react with what?
Limestone
What are two kinds of rocks that are easily weathered by carbonic acid?
Limestone and marble are two types of rocks that are easily weathered by carbonic acid due to their high calcium carbonate content. Over time, carbonic acid dissolves these rocks, leading to the formation of caves, sinkholes, and other karst landscapes.
Does carbonic acid dissolve every mineral?
No, carbonic acid does not dissolve every mineral. It most commonly dissolves minerals like calcite, dolomite, and limestone, which are composed of calcium carbonate. Other minerals may or may not be soluble in carbonic acid depending on their chemical composition and stability.
What does the formation of Karst topography require carbonic acid to react with?
The formation of Karst topography requires carbonic acid to react with limestone or other soluble rock materials, such as dolomite or gypsum. This chemical reaction dissolves the rock, creating features like sinkholes, caves, and underground drainage systems.
How does chemical weathering cause caves to form in limestone?
Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass.
What is carbonic acid and how does it effect rock?
Carbonic acid is a weak acid formed when carbon dioxide dissolves in water. It reacts with minerals in rocks, particularly calcium carbonate, causing chemical weathering. This process can lead to the breakdown of rock, contributing to erosion and the formation of caves, sinkholes, and other geological features.
How are limestone caves different to other caves?
Primarily in their mode of formation: dissolution of limestone by water acidified by atmospheric CO2 (forming carbonic acid).
Is carbonic acid an acid that forms caves?
Yes, carbonic acid (H2CO3) can dissolve limestone and other minerals in rocks to create caves over long periods of time through a process called carbonation. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is more soluble and leads to cave formation.
What ground water dissolves the limestone rock in a cave formation?
That indeed is how caves develop in limestone. The solvent is rain-water weakly acidified by having absorbed atmospheric carbon-dioxide. This may be augmented by organic acids from the soil, but the Carbonic Acid is the primary reagent.
