its all to do with gravitational pull, basically rainwater holds carbon dioxide as it is fresh from the atmosphere then when it reaches earth there is more added to it because us humans and animals take in oxygen and breathe out carbon dioxide.
Carbon from limestone returns to the atmosphere through the process of weathering. Rainwater and carbonic acid break down the limestone, releasing carbon dioxide into the air. This process is a natural part of the carbon cycle.
The most common natural acid on Earth's surface is carbonic acid, which forms when carbon dioxide dissolves in water. It is found in rainwater, rivers, lakes, and oceans.
Carbon dioxide becomes dissolved in rainwater and sinks into the soil, resulting in the creation of carbonic acid. This acid can weather marble due to its corrosive nature.
No, alkali rain is not a natural phenomenon. Rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, but it does not contain alkalis like sodium hydroxide or potassium hydroxide.
No, the natural cycle of carbon dioxide (CO2) moves through the land, oceans and atmosphere, and has done for millions of years. It is able to remove all the natural carbon in the air (and part of the global warming carbon as well). It is the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity that releases carbon that has been hidden underground for millennia that is increasing the carbon concentrations in the atmosphere.
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!
Carbon dioxide dissolves in normal rainwater, forming a weak carbonic acid solution. This process is a natural part of the carbon cycle and helps regulate the acidity of bodies of water.
Carbon dioxide dissolving in water to form carbonic acid, which lowers the pH. Rainwater picking up carbon dioxide in the atmosphere to form carbonic acid as it falls, resulting in slightly acidic rainwater.
Natural rainwater is typically more acidic than neutral water because it absorbs carbon dioxide from the atmosphere, forming carbonic acid. This makes rainwater slightly acidic with a pH around 5.6.
Carbonic acid is formed when rainwater reacts with carbon dioxide in the soil. This weak acid plays a role in the chemical weathering of rocks and minerals. Over time, carbonic acid can contribute to the formation of caves, sinkholes, and other geological features.
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6. The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). Carbon dioxide (CO2) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater. Hope this helps! :)
Unpolluted rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, which reacts with water to form carbonic acid. This natural acidity of rainwater is typically very mild and not harmful to the environment.

When rainwater reacts with carbon dioxide in the soil, it forms carbonic acid. This weak acid can further contribute to the weathering of rocks and minerals in the soil.
