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 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 types of bedrock are dissolved most easily by running water?
Bedrocks such as limestone, dolomite, and gypsum are easily dissolved by running water due to their solubility in water. These rocks contain minerals that are easily weathered and dissolved, resulting in the formation of features like caves, sinkholes, and underground rivers.
Which weathers faster feldspar or marble?
Marble weathers faster than feldspar because marble is more susceptible to chemical weathering due to its composition of calcium carbonate, which reacts easily with acidic rainwater. In comparison, feldspar is more resistant to weathering due to its hardness and chemical stability.
What minerals would be least immune to chemical weathering limestone quartz marble and granite?
The answer is marble because it is like glass and if there were a piece on the ground it could be easily broken but if there were a tornado the tornado couldnt break it. Marble is very fragile.
What becomes dissolved in rainwater and sinks into the soil the result is an acid that can weather marble?
acid rain
What becomes dissolved in rainwater and sinks into the soil that results in an acid that can weather marble?
acid rain
What becomes dissolved in rainwater and sinks into the soil the results is an acid that can weather marble?
acid rain
When becomes dissolved in rainwater and sinks into soil the result is an acid that can weather marble?
Carbon Dioxide
What has a result of acid rain that can weather marble when it dissolves in rainwater and sinks into the soil?
Carbon dioxide
What dissolves in rainwater and sinks into the soil the result is carbonic acids that can weather marble?
Carbon dioxide.
What are the effects of rainwater on carbonate rocks?
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 solubility of marble in normal rainwater for which pH5.60?
Marble is primarily composed of calcium carbonate, which is not very soluble in neutral water. It is generally not expected to dissolve significantly in rainwater with a pH of 5.6.

What happens when calcium carbonate reacts with rainwater?
When calcium carbonate reacts with rainwater, it forms a weak acid called carbonic acid. This reaction can lead to the erosion of limestone or marble surfaces over time. Additionally, it contributes to the process of chemical weathering in nature.
Why is marble useful for buildings and statues?
Marble is a very soft 'somewhat brittle' stone. This means that slabs of marble are relatively easy to carve and polish. However, when cut into hearth size slabs e.g. 3" thick x 5' long moving it becomes quite a task. Marble is also strong and durable and can withstand rough weather.
