Limestone is a type of rock that is chemically weathered by acidic groundwater. The acidity, often due to dissolved carbon dioxide forming carbonic acid, reacts with the calcium carbonate in limestone, leading to its dissolution. This process can create features such as caves and sinkholes in karst landscapes. Other carbonate rocks, like marble, can also be affected similarly.

Which type of rock was chemically weathered by acidic groundwater to produce ths features?
Limestone is the type of rock that is chemically weathered by acidic groundwater, leading to distinctive features such as karst landscapes, sinkholes, and caves. The acidic groundwater, often containing carbonic acid formed from carbon dioxide in the soil, dissolves the calcium carbonate in limestone, resulting in the erosion and creation of these geological formations. Over time, this process can lead to significant alterations in the landscape.
Is water in caves acidic?
Water in caves can vary in acidity depending on factors such as the rock composition and interactions with organic matter. In some caves, groundwater can become acidic due to the presence of minerals like sulfuric acid from rock weathering processes. However, not all water in caves is necessarily acidic, and some may be neutral or even slightly alkaline.
Rock that formed from other weathered rock is?
sedimentary
Is magma a weathered rock?
No. Magma is molten rock underground.
What happens to a metamorphic rock when its weathered?
When a metamorphic rock is weathered, it undergoes physical and chemical breakdown due to exposure to the elements. This can lead to the rock breaking apart into smaller pieces or being chemically altered, potentially forming new minerals. Over time, the weathering process can transform the metamorphic rock into sediment that may eventually become part of a sedimentary rock.
Which type of rock was chemically weathered by acidic groundwater to produce ths features?
Limestone is the type of rock that is chemically weathered by acidic groundwater, leading to distinctive features such as karst landscapes, sinkholes, and caves.

What type of rock is most easily dissolved by slightly acidic groundwater?
Limestone is the type of rock that is most easily dissolved by slightly acidic groundwater. This is due to its high calcium carbonate content, which can be easily weathered and eroded by the acidic water, causing the rock to dissolve over time.
Which is best at weathering rocks?
Most surface rock is weathered by water. Naturally acidic rain and groundwater can react chemically with rock, causing dissolution and oxidation. Freezing water can also act on the rock mechanically, forcing open gaps and faults for further weathering attack by liquid water.
How is limestone weathered?
Limestone is weathered by mechanical and chemical means:Mechanical: plant root growth in cracks and crevices, frost wedging, rock falls, abrasion.Chemical: exposure to fluids containing acids--particularly rainwater and flowing runoff that is naturally acidic--that chemically react with the calcium carbonate in the limestone, dissolving it.
How does the type of rock affect how it is chemically weathered?
It affects it by when you do it well, it happensedews
What are 3 things that cause mechanical weathering?
air oxidation, groundwater, and acid precipitation
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 dissolves limestone formations in some caves?
Acidic groundwater dissolves limestone formations in caves by chemically reacting with the calcium carbonate in the rock, forming calcium bicarbonate which is soluble in water. Over time, this process creates features such as stalactites and stalagmites.
If two identical rocks were weathered one mechnically and the other chemically how would the products of weathering for the two rocks differ?
Mechanical weathering would result in the physical break down of the rock into smaller pieces without changing its chemical composition. Chemical weathering would alter the mineral composition of the rock through processes such as hydration, oxidation, or dissolution, producing different minerals as products.
What are things that erode weathered rock?
things that erode weathered rock
Is feldspar mixing with acidic groundwater and producing clay minerals chemical or weathering?
This process is an example of chemical weathering. The feldspar reacts with the acidic groundwater to form clay minerals through a chemical reaction, altering the mineral composition of the rock.
Which rock type is most easily dissolved by groundwater?
Limestone is the rock type most easily dissolved by groundwater, due to its high solubility in acidic water. This process results in the formation of features such as caves, sinkholes, and underground streams.
