Is Water from an area which has a limestone and chalk strata most likely to be acidic?
No, water from an area with limestone and chalk strata is more likely to be alkaline, not acidic. Limestone and chalk are composed mainly of calcium carbonate which can increase the alkalinity of water through a process called calcification.
What type of rock is dissolved by slightly acidic groundwater?
Slightly acidic groundwater can dissolve limestone, which is a type of sedimentary rock made up of calcium carbonate. Over time, the acidic water can create underground caves and formations such as stalactites and stalagmites.
Why rainwater is able to attack limestone?
Rainwater contains carbon dioxide, which dissolves in the water to form a weak carbonic acid. When this acidic rainwater comes into contact with limestone, a chemical reaction occurs where the acid dissolves the calcium carbonate in limestone, leading to the erosion and dissolution of the rock over time.
Why most caves form by limestone?
Limestone is susceptible to dissolution by acidic water, which is common in most natural environments. Over time, this dissolution process carves out cavities underground, leading to the formation of caves. Additionally, limestone is a common and widespread rock type, which contributes to the prevalence of limestone caves.
What affect does pH have on the erosion of limestone?
Lower pH levels, such as acidic conditions, can enhance the rate of erosion of limestone due to the chemical reaction between the acidic water and the calcium carbonate in the limestone causing it to dissolve more readily. Higher pH levels, such as alkaline conditions, can help protect limestone from erosion by reducing the solubility of calcium carbonate.
Why is water acidic when it reaches a limestone?
it the limestone is acidic
How can a limestone cave be formed?
From dissolution and erosion of limestone by acidic water over time.
What will happen to limestone if acidic water flows across it?
Limestone is mainly composed of calcium carbonate, which can react with acidic water to form soluble calcium ions and carbonate ions. This process dissolves the limestone, leading to the erosion and weakening of the rock over time.
Is Water from an area which has a limestone and chalk strata most likely to be acidic?
No, water from an area with limestone and chalk strata is more likely to be alkaline, not acidic. Limestone and chalk are composed mainly of calcium carbonate which can increase the alkalinity of water through a process called calcification.
Is limestone acidic basic or neutral?
Limestone is a basic (alkaline) substance. It has a pH greater than 7, meaning it helps to neutralize and balance acidic conditions in soil or water.
Does limestone turn water blue?
No, limestone is a sedimentary rock that is the basis for marble if it is compressed by millions of years of pressure. Limestone consists of calcium carbonate, CaCO3. Limestone dissolved in slightly acidic water forms the basis of stalactites and stalagmites in limestone caves.
A depression in the ground due to cave collapse or acidic water dissolution of limestone is called a?
A sinkhole is the term used to describe a depression in the ground caused by a cave collapse. It can also be the result of acidic water dissolving limestone.
How can the water cycle make acidic water go everywhere?
The pollutants in air make rain water acidic. Rain water, containing acid reaches everywhere .
What could take a layer of limestone away from a fossil?
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.
What happens when water reaches an impermeable layer?
When water reaches an impermeable layer, such as a layer of rock or clay, it cannot pass through or be absorbed by the layer. This can lead to the water pooling on top of the impermeable layer, causing waterlogging or the formation of a water table. It can also lead to the creation of wetlands or lakes in certain circumstances.
What type of rock is dissolved by slightly acidic groundwater?
Slightly acidic groundwater can dissolve limestone, which is a type of sedimentary rock made up of calcium carbonate. Over time, the acidic water can create underground caves and formations such as stalactites and stalagmites.
What do you call caves made by water?
Karst caves, and it is the majority of caves; formed by acidic ground-water dissolving the limestone.
