Which process has occurred when limestone in the earth has been eaten away by carbonic acid?
The process that occurs when limestone is eaten away by carbonic acid is called chemical weathering, specifically carbonation. When carbon dioxide (CO2) dissolves in water, it forms carbonic acid (H2CO3), which can react with calcium carbonate (the primary component of limestone) to create calcium bicarbonate. This reaction leads to the dissolution of limestone, often resulting in features like caves and sinkholes.

Does carbonic acid melt limestone?
No, it can't. Limestone melts only at high temperatures. But carbonic acid can, over the course of time, attack and dissolve a lot of limestone. Here's the deal, and it's on the mark. The atmosphere contains mostly nitrogen and oxygen as you know, but there's a bit of darbon dioxide in there, too. And water in the air picks up CO2 and becomes carbonic acid. This is carried to earth in rain. This doesn't "affect" rain all that much, but it does lower the pH of rain a bit. And the carbonic acid, though it is weak, will seep into the ground where limestone layers form an under layer and slowly, over the course of geologic time, dissolve the limestone to create some fantastic caves!
How is carbonic acid produced?
Carbonic acid is produced when carbon dioxide gas dissolves in water to form carbonic acid, following the reaction CO2 + H2O ⇌ H2CO3. This process occurs naturally in the Earth's atmosphere, especially in oceans where the acid contributes to the regulation of the Earth's climate.
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 is it possible that a limestone rock change into marble?
Limestone can change into marble through a process called metamorphism, which involves high pressure and temperature deep within the Earth's crust. This process recrystallizes the minerals in the limestone, resulting in a more compact and harder rock with a different texture and appearance, known as marble.
A metamorphic rock made from limestone?
Marble is a metamorphic rock formed from limestone that has undergone intense heat and pressure deep within the Earth's crust. The process of metamorphism recrystallizes the original minerals in limestone to create the distinct crystalline structure and smooth texture of marble. Marble is valued for its beauty and is commonly used in architecture and sculpture.
What process has occurred when limestone in the earth has been eaten away by carbonic acid?
The process is called chemical weathering. Carbonic acid, formed from the reaction of carbon dioxide in the atmosphere with water, reacts with the calcium carbonate in limestone, dissolving it and breaking it down over time. This process creates features such as caves, sinkholes, and karst topography.
Does carbonic acid melt limestone?

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.
How does limestone change into marble?
Limestone changes into marble through a process called metamorphism. This process involves the recrystallization of the calcite mineral in limestone due to high pressure and temperature deep within the Earth's crust. This transforms the limestone into a more compact, harder, and denser rock known as marble.
How does carbonic acid eventually get to the earth?
Carbonic acid forms when water reacts with carbon dioxide.
When rain and CO2 combines what happens?
When rain combines with CO2, it forms a weak acid called carbonic acid. This process is known as carbonation. Over time, carbonic acid can react with and dissolve certain minerals in rocks, contributing to weathering and erosion of the Earth's surface.
How does Limestone turn to Marble Is it extreme heat or pressure?
Limestone turns into marble through a process called metamorphism, which involves both heat and pressure. The minerals in the limestone recrystallize under the combination of high temperature and pressure, transforming it into marble. This process can occur over millions of years deep within the Earth's crust.
How limestone turns to marble?
Extreme heat and pressure.
How is marble formed and what are the key processes involved in its creation?
Marble is formed from limestone that undergoes a process called metamorphism. This process involves high pressure and temperature deep within the Earth's crust, causing the limestone to recrystallize and form marble. The key processes involved in its creation are heat, pressure, and the presence of fluids that help facilitate the transformation of limestone into marble.
How can marble turn back into limestone?
Marble can turn back into limestone through a process called metamorphism. When subjected to high pressure and temperature underground over long periods of time, the minerals in marble can recrystallize and rearrange to form limestone. This transformation occurs in the Earth's crust, where the conditions favor the alteration of marble back into limestone.
How is carbonic acid produced?
Carbonic acid is produced when carbon dioxide gas dissolves in water to form carbonic acid, following the reaction CO2 + H2O ⇌ H2CO3. This process occurs naturally in the Earth's atmosphere, especially in oceans where the acid contributes to the regulation of the Earth's climate.
