Can dissolve limestone when mixed with water?
Limestone can dissolve in water when it is mixed with carbon dioxide, forming carbonic acid. This weak acid reacts with the calcium carbonate in limestone, leading to its dissolution. This process is a key factor in the formation of caves and karst landscapes. Additionally, acidic rainwater can also enhance the dissolution of limestone.
True that A funnel-shape depression of limestone dissolve by rain is called a cave?
No, a funnel-shaped depression in limestone caused by dissolution from rainwater is typically called a "sinkhole," not a cave. Sinkholes form when the surface layer collapses into an underground void, while caves are larger, underground chambers formed through the continuous erosion of limestone by acidic water over time. Both are features of karst topography but refer to different geological formations.
What is three karst features?
Three common karst features are sinkholes, caves, and limestone pavements. Sinkholes are depressions or holes in the ground caused by the collapse of a surface layer, often due to the dissolution of limestone. Caves form through the erosion of limestone by acidic water, creating intricate underground passages and chambers. Limestone pavements are flat or gently undulating surfaces characterized by clints (blocks of limestone) and grikes (fissures), formed by the weathering process.
What type of bedrock most likey exists in an area that has numerous sinkholes?
Areas with numerous sinkholes typically have limestone bedrock, as it is prone to dissolution through a process called chemical weathering. This occurs when acidic water percolates through the limestone, creating underground cavities. Over time, these cavities can collapse, leading to the formation of sinkholes. Other soluble rocks, such as gypsum or salt, can also contribute to sinkhole formation, but limestone is the most common.
What forms when limestone found in the earth has been eatin away?
When limestone is eaten away, it forms various features such as sinkholes, caves, and underground tunnels. This process occurs due to the dissolution of the limestone by acidic groundwater. The result is the creation of unique and sometimes expansive underground landscapes.
How can a limestone cave be formed?
From dissolution and erosion of limestone by acidic water over time.
A funnel-shaped depression of limestone dissolved by rain is called a cave?
While a funnel-shaped depression of limestone eroded by rainwater is called a limestone pavement or a doline, a cave is a naturally occurring underground void typically formed through chemical weathering and erosion processes such as the dissolution of limestone by acidic groundwater.
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.
Why do caverns and sinkholes form?
Caverns form through the gradual dissolution of limestone by acidic groundwater, creating underground openings. Sinkholes occur when the roof of these caverns collapse, or when there is a sudden collapse of the surface layer due to erosion of underlying material like limestone or salt deposits. Both geological processes are commonly found in areas with soluble bedrock.
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.
How is limestone cave in Aruba formed?
Same way as any limestone cave: dissolution of the rock by weakly acidic water flwoing through fractures and other discontinuities.
Can dissolve limestone when mixed with water?

What forms when limestone found in the earth has been eaten away?
Dissolution features such as dolines and sink holes as well as caves are common when limestone wihin the earth is dissolved.
What type of weathering causes the formation of an underground cave?
This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
Do sinkhole form by physical or chemical weathering?
Sinkholes are primarily formed by chemical weathering processes, specifically the dissolution of soluble rock such as limestone or gypsum by acidic water. However, physical weathering processes like erosion and the collapse of surface material can also contribute to sinkhole formation.
