Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Can limestone be worn away?
Yes, limestone can be worn away over time through processes like erosion and weathering. Physical forces such as wind, water, and ice can gradually break down limestone rocks, leading to their erosion and the formation of features like caves, sinkholes, and limestone pavements.
Which most promotes chemical weathering in limestone?
Carbonic acid, formed when carbon dioxide dissolves in rainwater, is the main driver of chemical weathering in limestone. As the carbonic acid comes into contact with the limestone, it reacts to dissolve and break down the rock, leading to the formation of features such as caves, sinkholes, and karst landscapes.
When acid rain falls on limestone what type of weathering occurs?
When acid rain falls on limestone, chemical weathering called dissolution occurs. The acidic rainwater reacts with the calcium carbonate in the limestone, causing it to dissolve and gradually wear away the rock over time. This process can result in the formation of features such as caves and sinkholes.
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
.Is it possible for any of the earth material scenes to be affected by both mechanical and chemical weathering If so describe the scene and situations.?
Yes, it is possible for a scene to be affected by both mechanical and chemical weathering simultaneously. For example, a limestone cliff can be subject to both physical breakdown due to mechanical weathering like freeze-thaw cycles, and chemical weathering from acid rain slowly dissolving the limestone. This combination can lead to the formation of caves and other unique rock formations.
Is limestone with holes mechanical or chemical weathering?
Limestone with holes is typically a result of chemical weathering. The holes are often created through the process of carbonation, where carbonic acid in rainwater reacts with the calcium carbonate in limestone to dissolve it and create cavities over time.
Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Is clay formation a result of mechanical or chemical weathering?
Clay formation is primarily a result of chemical weathering, where minerals in rocks are broken down by chemical processes to form clay minerals.
Can limestone be worn away?
Yes, limestone can be worn away over time through processes like erosion and weathering. Physical forces such as wind, water, and ice can gradually break down limestone rocks, leading to their erosion and the formation of features like caves, sinkholes, and limestone pavements.
What event is an example of chemical weathering?
The formation of caves due to the dissolution of limestone by acidic rainwater is an example of chemical weathering. This process results in the gradual breakdown of the rock through chemical reactions.
What is weathering and it's type with real life application?
Weathering is the process by which rocks and minerals are broken down into smaller pieces by various chemical, biological, and physical processes. The two main types of weathering are mechanical (physical breakdown of rocks) and chemical (chemical alteration of rocks). A real life application of weathering is the formation of caves through the dissolution of limestone by acidic groundwater.
Is acid chemical weathering or mechanical weathering?
chemical
Are speleothems mechanical or chemical weathering?
Speleothems are formed as a result of chemical weathering processes. Groundwater percolating through limestone or other soluble rocks dissolves minerals, and when the water reaches the cave, these minerals are deposited as speleothems such as stalactites and stalagmites through precipitation.

This process can result in the formation of features such as caves and sinkholes.
What is antonym for mechanical weathering?
The antonym for mechanical weathering is chemical weathering. Chemical weathering is the breakdown of rocks and minerals through chemical reactions, while mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.
