Rainwater, which is slightly acidic due to dissolved carbon dioxide, can weather carbonate rocks like limestone and marble through a process called chemical weathering. This reaction leads to the dissolution of calcium carbonate, resulting in the formation of features such as caves and sinkholes. Over time, this process can significantly alter the landscape and contribute to soil formation. Additionally, the dissolved minerals from the rocks can impact groundwater quality and ecosystem health.

What is the effects of carbonate racks to global climate?

There are two effects of carbonate rocks to the global climate. The two effects of carbonate rocks to the global climate are dissolution and deposition.


What type of carbonate rocks are susceptible to karst weathering?

Limestone and dolostone are the primary types of carbonate rocks susceptible to karst weathering. These rocks are composed mainly of calcium carbonate (in limestone) or magnesium carbonate (in dolostone), which can easily dissolve in acidic conditions, often created by carbonic acid from rainwater. This dissolution process leads to the formation of characteristic karst features such as sinkholes, caves, and underground drainage systems. The extent of karst development depends on factors like rock composition, topography, and climate.


When rainwater seeps through cracks in rocks what is called?

When rainwater seeps through cracks in rocks, it is called infiltration.


Why carbonate rocks are most affected by acid rain?

Limestone is calcium carbonate. The reaction that occurs when acid rain damages carbonate rocks is an acid-base reaction. Hydronium ions in the rain reaction with carbonate ions in the rock to form hydrogen carbonate, which is water soluble. The overall reaction is represented by H3O+ + CO32- => H2O + HCO3-


Calcium carbonate is a major component of which sedimentary rocks?

Calcium carbonate is a major component of sedimentary rocks such as limestone, chalk, and marble. These rocks form from the accumulation of marine organisms' shells, coral reefs, and precipitated calcite minerals.

What rocks are dissolved by rain?

Rainwater can dissolve rocks that contain minerals such as limestone, chalk, and marble, which are mostly made of calcium carbonate. These rocks are easily weathered by the acidic properties of rainwater, leading to the process of dissolution. Over time, this can result in the formation of features like caves, sinkholes, and karst topography.


What is an example of chemical weathering affecting the rocks?

Rainwater is slightly acidic and will react with the calcium carbonate found in limestone and other rocks. The resultant erosion is an example of chemical weathering.


Explain how carbonic acid weather rocks?

Carbonic acid, formed when carbon dioxide dissolves in water, can increase the acidity of rainwater. This acidic rainwater can react with rocks containing calcium carbonate, such as limestone, leading to their dissolution over time. The carbonic acid breaks down the calcium carbonate in the rock, causing it to weather or erode.


Do all rocks react with rainwater at the same rate?

No. Rainwater is usually slightly acidic because of the carbon dioxide dissolved in it. Sometimes, it can be strongly acidic, if pollutants like sulphur dioxide and nitrogen dioxide are dissolved in it. Both weakly and strongly acidic rainwater react with some rocks, but only ones that are alkaline. Chalk is almost pure calcium carbonate and reacts fairly quickly with rainwater. Other rocks that contain calcium carbonate include limestone and marble and these react a little more slowly. But some rocks, like sandstone, are actually acidic and don't react with rainwater (though they are still physically weathered by rain). Granite also doesn't react with rainwater and it physically weathers much more slowly.

What makes rainwater able to dissolve carbonate rocks?

A compound called calcium hydrogencarbonate is the main cause of hard water. It forms when rain falls on limestone and chalk rocks. These rocks are made of calcium carbonate, which is insoluble in water. Because rain water contains carbon dioxide, dissolved from the air, this makes it acidic. The rain water reacts with the rocks to form calcium hydrogencarbonate which is soluble. This is the white solid that ends up in our kettles. An equation for the reaction is: water + carbon dioxide + calcium carbonate = calcium hydrogencarbonate H2O (l) + CO2 (g) + CaCO3 (s) = Ca(HCO3)2 (aq)


How did CO2 get locked in carbonate rocks?

Carbon dioxide can get locked in carbonate rocks through processes such as weathering of rocks containing carbonates, which leads to the formation of bicarbonate ions that eventually get precipitated as carbonate minerals (e.g., calcite) in rocks. Over time, this process sequesters CO2 in the form of carbonate minerals in the rocks.


What rocks dissolve fastest?

Limestone and marble tend to dissolve the fastest among common rocks due to their high solubility in acidic solutions. Their main constituent, calcium carbonate, is easily weathered by rainwater or acidic substances, leading to faster dissolution compared to other rock types like granite or basalt.
